The NB linear system is a linear motion mechanism which utilizes the recirculating movement of ball or roller elements to provide smooth and accurate linear travel. NB offers a wide range of linear motion products that may contribute to the size and weight reduction of machinery and other equipment, while providing dependable performance in highprecision equipment.

ADVANTAGES Low Friction and Excellent Response:

High Load Capacity and Long Travel Life:

The dynamic friction of rolling ball or roller elements is substantially lower than that of full-face surface sliding friction. Since the difference between rolling dynamic and static friction is small, motion response is excellent and results in superior dependable movement. This also allows for easy fabrication of mechanisms requiring precise positioning or highspeed acceleration.

Although the NB linear system is designed to be compact, the use of large rolling elements and machined raceway surface results in high load capacity and long travel life.

High Precision and Smooth Movement:

Variety of Models:

The NB linear system is designed for smooth rolling movements. The rolling element's raceway contact surface is finished through high-precision grinding. The recirculating movement of the rolling elements allow for continuous high-precision linear movement without clearance.

A wide variety of models and types of NB systems are available for just about any shape or material option. This permits the selection of the best appropriate linear component for any application.

Ease of Installation: The NB linear system shortens machining and assembly time when compared with that of a full face surface sliding bearing system.

ALLOWABLE LOAD Load and Moment:

Figure 1-1 Load and Moment

A load may be exerted to a linear system as depicted in Figure 1-1. In addition, a moment may be applied to a slide guide. Each type of load addressed by NB is described as follows.

rated loads C and Co

load

Basic Static Load Rating and Allowable Static Moment: Under excess or impact load conditions applied to a linear system while it is stationary or moving slowly, a permanent deformation occurs on either the rolling surface or the rolling elements. When this deformation exceeds a predictable level, it becomes a source of vibration and acoustic noise during operation and will also result in rough motion and shortens life. To prevent this permanent deformation and deterioration in movement accuracy, a basic static load rating (Co) is given as an allowable load. This basic static load rating is defined as the static load that results in the maximum allowable stress at the center of the contact surface between the rolling elements and the rolling surface. The sum of the permanent deformation of the rolling elements and that of the rolling surface is 1/10,000 the diameter of the rolling elements. In linear systems, a moment may also be present when applied in addition to the static load. The allowable static moment is defined by MP, MY, and MR, which are illustrated in Figure 1-1.

direction of moment pitch

yaw

roll

Allowable Load and Static Safety Factor: The basic static load rating and allowable static moment define the maximum static load in each direction. These maximum static loads are not necessarily applicable depending on the operating conditions, the mounting accuracy, and the required motion accuracy. Therefore, an allowable load with a safety factor that covers these factors must be obtained. In general, the minimum static safety factor is based on the values as listed in Table 1-1.

BALL SPLINE ROTARY BALL SPLINE

LIFE If a linear system reciprocates when it is under a load, a continuous stress acts on it, ultimately causing flaking of its rolling elements and/or rolling surfaces due to material fatigue, making it inoperable. The distance a linear system travels before this flaking condition first occurs is called the life of the system. A linear system can also become inoperable due to sintering, cracking, pitting, or rusting. These factors are differentiated from those affecting the life because they are related to installation accuracy, operating environment, or the selected lubrication method of the installer.

The rated lifetime estimation depends on the type of rolling element used. Both Equations (3) and (4) are used for ball and roller elements respectively. In cases when torque loading is applied, Equation (5) is to be used. When a ball is used as the rolling element,

Numerous variables, such as guide rail accuracy, mounting conditions, operating conditions, vibration and shock while under linear motion affect an actual application. Therefore, calculating the actual applied load accurately is extremely difficult. In general, the calculation is simplified by using coefficients representing these effects. These coefficients include hardness (fH), temperature (fT), contact (fC), and applied load (fW). By using these coefficients, Equations (3)  (5) can be expressed by Equations (6)  (8).

The life of a linear system is expressed in terms of the distance traveled. Therefore, the life of a linear system is calculated using the allowable load that corresponds to a certain distance traveled. This allowable load is a measure of the system's performance relative to the applied load and is called the rated basic dynamic load. It is defined as a constant-direction load with a magnitude corresponding to a life of 50x103 m. In some cases or linear systems, the basic dynamic load rating may vary depending on the direction of the applied force. In the NB Linear System catalog, the value of the basic dynamic load rating is assumed when a force is applied from directly above and is indicated in the dimension tables. For ball splines, the linear motion may involve torque loading, so the basic dynamic torque rating is defined in a similar fashion.

STROKE BUSH SLIDE ROTARY BUSH

Even when two linear systems are manufactured at the same time, have the same part number, and are used under identical conditions, their lifetimes can differ due to differences in their fatigue failure characteristics. This prevents determining the life of any particular linear system. Therefore, the rated life is determined statistically and is defined as the distance 90% of linear systems travel before experiencing flaking.

Life of a Linear System:


If the distance traveled per unit time is known, the life can be expressed in terms of time, which may be easier to understand. The relationship between the stroke distance, the stroke frequency per minuit, and the life time is expressed by Equation (9)

Hardness Coefficient (fH):

n1 : stroke frequency per min.(cpm)

Figure 1-2 Hardness Coefficient Hardness Coefficient, fH

In a linear system, the guide rail serves the same purpose as an inner race of a ball bearing. Therefore, the hardness of the guide rail plays an important role in determining the rated load. If the surface hardness is less than HRC58, the rated load is reduced. NB uses an advanced heat treatment method to maintain an appropriate level of hardness. However, if guide rails with inadequate hardness must be used, the rated load must be re-calibrated based on the hardness coefficients given in Figure 1-2.

L103 Lh =   (9) 2sn160

Temperature Coefficient (fT):

Tracking Surface Hardness, HRC

Contact Coefficient (fC): When two or more linear systems are used in contact with each other, the variation in each system and the accuracy of the mounting surfaces must be taken into consideration. In general, the coefficient values given in Table 1-2 should be used to compute the life.

Figure 1-3 Temperature Coefficient Temperature Coefficient, fT

NB linear systems are heat treated to reduce the amount of wear. Therefore, if the operating temperature exceeds 100 , hardness is reduced and the life of the system is shortened. The variation in hardness with temperature is shown in Figure 1-3.

Applied Load Coefficient (fW): When computing the applied load, the weight of the mass, inertial force, moment resulting from the motion, and the variation with time should be accurately estimated. However, it is very difficult to accurately estimate the applied load due to the existence of numerous variables, including the start/stop conditions of the reciprocating motion and of the shock/vibration. Estimation is simplified by using the values given in Table 1-3.

The load applied to a linear system generally varies with the distance traveled depending on how the system is used. This includes the start/stop processes of the reciprocating motion. The average applied load is used to compute the life corresponding to the actual application conditions. 1. When the load varies in a step manner with the distance traveled (Figure 1-4) and 1 is the distance traveled under load P1, 2 is the distance traveled under load P2, and n is the distance traveled under load Pn, the average applied load, Pm is obtained by the following equation

RIGIDITY AND PRE-LOAD Effect of Pre-load and Rigidity:

Figure 1-7 Contact Structure of SGL Slide Guide

The rigidity of a linear system must be taken into consideration when it is to be used in high-precision positioning devices or high-precision machinery. Preloaded slide guides and ball splines, which use a ball as the rolling element, are available upon request to meet the need for greater rigidity. If a force is applied to the ball elements without a pre-load, an elastic deformation proportional to the applied force to the 2/3 power will result. 2/3 W(8)  : elastic deformationW : applied force

Contact NB for further information on rigidity.

Types of Pre-Load and its Specification: Pre-load is categorized into three primary ranges: normal, light, and medium. At NB, pre-load is applied by installing rolling elements that are slightly larger than normal. Therefore, the specification of the preload is expressed by a negative gap value.

Figure 1-8 Applied Load vs. Elastic Deformation of Steel Balls

elastic deformation

Therefore, the elastic deformation is relatively large during the initial loading stage, however then becomes smaller as the load increases. The contact angles for all of the ball elements in SGL slide guides are the same as shown in Figure 1-7. Therefore, if the pre-load (P1) applied results in an elastic deformation of 1, the deformation will vary linearly with the applied load until the elastic deformation of the ball element on the other side cross the race becomes zero, as depicted in Figure 18. This permits the determination of the deformation of linear systems. The ratio between the applied load and the elastic deformation is defined as the rigidity of the system. Equation (9) can be used to determine the elastic deformation with an applied load of up to 2.8 times the pre-load. 2/3 2/3 21 2P 1 P 2 (9) P 2 22  P 1

However, the values given in Table 1-6 are used for the normal loading condition (20% of basic dynamic load rating) without any pre-load. The seal resistance depends on the seal-lip condition as well as on the condition of the lubricant and does not change proportionally with the applied load, which commonly is expressed by a constant value of 2 to 5 N.

OPERATING ENVIRONMENT Temperature Range: NB linear systems are heat-treated in order to harden the surface. Because of this, if the temperature of the system exceeds 100, the hardness and rated load will be reduced (refer to page Eng. 5, hardness coefficient). If resin is used in any one of the components, the system cannot be used in a high-temperature environment.

Dust and perticle debris will adversely affect the motion characteristics of a linear system. They can also cause abnormally fast wear. In a normal operating environment, the use of seals may prevent adverse effects to the linear system. However, the linear system should be well protected by using bellows or a protective cover when it is used in an extremely hostile environment. (Figure 1-10)

K GREASE

SLIDE BUSH

K grease is a low dust generation lubricant for linear systems that provides long-term and stable dust control. This particular type has very few impurities, yet its lubricating effect, contamination control, and rust prevention characteristics are equivalent to that of lithium soap grease.

TOPBALL PRODUCTS SLIDE UNIT STROKE BUSH SLIDE ROTARY BUSH

The objective of lubrication includes the reduction of friction between the rolling elements and the rolling surfaces, prevention of pitting, reduction of wear, and the prevention of rusting by forming a film over the surfaces. To maximize the performance of a linear system, a lubrication method and a lubricant appropriate for the operating environment should be selected. Methods of lubrication include oil lubrication and grease lubrication. For oil lubrication, turbine oil conforming to ISO standard VG32-68 is also recommended. For grease lubrication, lithium soap based grease is recommended. A rust preventative oil that does not adversely affect the lubricant is applied in a slide bush. The slide bush should be lubricated before it is placed into service. Products with raceway grooves, such as slide guides, are delivered pre-lublicated with grease and may be installed and used without further lubrication. Through operation lublicant is dispersed, so it is advisable to re-lubricate periodically based upon apprication usage.

ACCURACY MEASUREMENT METHOD The accuracy of slide guides is measured by fixing the rail to the datum base. The accuracy is expressed in terms of the average value at the center portion.

Dimensional Tolerance and Paired Guide Difference:

Figure A-1 Accuracy Measurement reference surface

The accuracy of the slide guide is obtained by measuring the height, H, and width, W, as shown in Figure A-1. The dimensional tolerance is measured for each of the blocks attached to the rail and is expressed in terms of the deviation from the reference value. The paired-guide difference is obtained by measuring the blocks attached to the rail and is expressed in terms of the difference between the maximum and minimum values.

Motion Accuracy:

NB mark

Figure A-2 Measurement Method for Motion Accuracy

The rail is first fixed to the reference base. The motion accuracy is obtained by measuring the difference in the indicator readings when the block is moved along the entire span of the rail. reference base

Notation for Number of Rails and Paired Guide Difference:

type of vibration symbol pre-load absorption ability

SLIDE UNIT

A pre-load causes internal stress within the slide guide, resulting in some reduction in lifetime. However, when the part is used under shock or vibration loading conditions, a pre-load will absorb the load and will actually help lengthen the life of the part. Because the pre-load causes elastic deformation of the rolling elements, it becomes less tolerable to the installation dimensional difference. Extreme care should be exercised in machining the installation surface.

P1:pre-load P2:zero pre-load

TOPBALL PRODUCTS

The rolling elements of the slide guide deform elastically due to the applied load. The amount of deformation depends on the type of rolling element. It is proportional to the 2/3rd power for ball elements. For rollers, it is proportional to the 0.9th power. In either case, the amount of deformation decreases as the applied load increases. Greater rigidity is achieved by applying a pre-load.

Mounting Surface Shape and Accuracy:

Figure A-7 Shape of Mounting Surface

NB slide guides are designed and fabricated to be accurately mounted by attaching them to a machined mounting base. One approach is to provide a shoulder on the mounting surface and align the reference surface of the rail or block against this surface (Figure A-7). To avoid corner interference, an escape groove should be provided at the shoulder corner or the radius of the shoulder corner should be smaller than the radius of the slide guide corner. The accuracy of the rail surface affects the accuracy of the machinery or other equipment along with the slide guide motion accuracy. The accuracy of the mounting surface should be equivalent to that of the desired slide guide motion accuracy. The specified pre-load may not be achieved due to deformation of the block, for example, the mounted block surface is not flat. Refer to Figure A-8. Careful attention should therefore be given to achieve the specified flatness.

Figure A-8 Effect of Flatness

Reference Surface Indication: Reference surfaces are provided to enable accurate and simplified mounting. They are placed in the same direction on the block and the rail, as shown in Figure A-9. They are located on the side opposite to the NB mark. Depending on the mounting arrangement, the standard reference surface may not ensure mounting accuracy (for example, 1 rail sideway or 2 rails opposing, page A7, Figure A-6). In such cases, NB can provide a reference surface on the opposite side. This should be specified when ordering.

Mounting:

 Applications where shock/vibration loading and high load are involved and high accuracy is required. The effect of shock and vibration on accuracy is eliminated by mounting on the slide guide a side piece, which is typically a side plate (Figure A-10), tightening set screws (Figure A-11), or a tapered gib (Figure A-12).

Figure A-11 Mounting of Tightening Set Screw reference side

TOPBALL PRODUCTS

In general, a slide guide is used with 2 rails in parallel. In that case, one rail is on the so-called reference side and the other is the so-called adjustable side.

SLIDE BUSH

Because space is limited in the guide rail portion, small screws must be used. Use as many screws as necessary for the length of the rail.

Mounting Method:

Figure A-16 Mounting Using Reference Surfaces

When reference surfaces are provided for both the table and the base, use the following procedure to mount the slide guide. 1. Remove burrs, scratches, dust, etc. from the base and table. Apply a low viscosity oil to the base and the table. Place the slide guide on the base carefully. Temporarily fix the rail mounting bolts. 2. Tighten the screw for the side piece so that the installation reference surface and the rail reference surface are in contact. If a side piece is not provided, use a C clamp to position the mounting reference surface and the rail reference surface so that they contact each other. 3. Tighten the mounting bolts to the specified torque, and complete the mounting of the rail. The rail is designed so that its accuracy is optimum when the bolts are tightened to the specified value. Refer to the recommended torgue table for each product type for the specified torque.

When a side piece is not provided.

4. Repeat steps 2 and 3 for the rail on the adjustable side. 5. Move the blocks at the mounting location of the table, and place the table softly. Then slightly tighten the screws. 6. Position the reference surface of the block against the table. Tighten the mounting screws in a diagonal sequence. 7. Repeat steps 5 and 6 for the block on the adjustable side.

The SEB and SER slide guides do not have ball element retainers, so if they must be removed from the mounting rail, use a temporary rail to prevent the ball elements from falling out will be necessary. Although the SGL and SGW slide guides do have ball element retainers, the ball elements may still fall out depending upon how the guide block is removed from the rail and also the pre-load condition. The use of a temporary rail is strongly recommended to prevent damage to the guide block (Figure A-20). Contact NB for information on temporary rails.

Note:

SLIDE SHAFT

When a reference surface is not provided on the reference side, mount the 2 rails by using a reference surface in the vicinity of the slide guide, as illustrated in Figure A-18. Temporarily fix the slide guide to the base, and mount an indicator on the block. Two or more blocks should be used; they should be fixed using a measurement plate (Figure A-18). Place the indicator against the reference surface of the base. Tighten the bolts from one end of the rail to ensure straightness. If there is no reference surface handy, use a straight edge to achieve straightness (Figure A-19).

RAIL LENGTH Guide Rail Length: Single rails are fabricated as standards to the lengths shown in the dimensional tables for each type and series. Unless otherwise specified, the distance to the first hole from one end of the rail (referred to as dimension "N") is within the range specified in the dimensional tables. The guide rail is therefore fabricated according to the equation given below. For other than standard dimensional requirements, contact NB.

Figure A-22 Guide Rail Grinding Method

L = M P + 2N

L : length (mm) N : distance to the first hole center from the end of the rail (mm) P : hole pitch (mm) M : number of pitches.

Note: Slide guide rails are machined with mounting holes as depicted in Figure A-21 during the initial fabrication process (before heat treatment). Specifying a different hole pitch or size will increase the cost and lead time, so please try to avoid changing these specifications.

JOINT RAILS Please keep the following points in mind when using joint rails.  To avoid dislocation at joints due to shock loading, provide a shoulder at the joint on the installation side.  Use the joint marks provided.  Tightly butt the rails to be joined so that there is no gap between them.

Rails can be joined together to obtain a length which exceeds the specified maximum standard length. There are two ways to do this.  Place the joints at the same location for the right and left rails so as to make the design and maintenance simple (Figure A-23 ).  Place the joints for the right and left rails at different locations so that the block does not move over the two joints at the same time so as to minimize the effect of the joint on accuracy (Figure A-23 ).

Notes: The standard accuracy and pre-load grade are only available on joined rail systems. The SER type guide series can not be made with joined rails. Contact NB for further information on joining .

Miniature (SEB Type)

The SEB type slide guide is a linear motion bearing in which the ball elements roll along two tracking grooves. This is the smallest and lightest slide guide series offered by Nippon Bearing. The compact design allows for the size and weight of machinery and other equipment to be reduced.

STRUCTURE AND ADVANTAGES The SEB type slide guide consists of a rail with precisely machined raceway grooves and a block assembly consisting of the main body, return caps and ball elements. Side-seals are available as an optional feature.

Moment Resistant:

Space Saving:

Tapped-Hole rail Types:

The 2-row 4-point contact design reduces the height, allowing the design of compact machinery and other equipment.

Slide guides with clearance holes are standard and tapped holes are available upon request.

A wide block "WA" type, a long block "AY" type, and a wide/long block "WAY" type are moment resistant slide guides available. One of these should be suitable for any demanding operating condition.

Anti-Corrosion: Super Compact:

The SEBS type slide guide uses Martensite stainless steel which is highly resistant to corrosion and may be used in hostile environments.

The SEBS5A slide guide has an overall height as small as 6 mm and the rail width as narrow as 5 mm.

Miniature (SER Type)

The NB SER type slide guide is a linear motion bearing utilizing the rotational motion of precision rollers placed in two rows. Despite its compact shape, it can be used in various applications requiring high load capacity.

STRUCTURE AND ADVANTAGES The NB SER type slide guide consists of a rail with two precision-machined raceway grooves and a block assembly. The block assembly consists of a main body, rollers, and bottom roller retainers. All of these components are made of metallic materials.

Moment Resistant Type:

High Load Capacity and Long Life:

Rail Bolt Hole Types:

Since roller elements are used, the contact surface is large which provides a high load capacity and long travel life.

SER type rails with counterbore bolt holes (standard) and optional tapped mounting holes (N-type) are available enabling various installation methods.

Compactness:

All Stainless:

Since a cross roller method is utilized, only two raceway grooves are necessary and presents a very compact package.

Since all the components for the SER type guide are made of metallic materials, stainless steel provides excellent corrosion and thermal characteristics. The SERS type slide guide is ideal for clean-room or vacuum applications.

The wide block design (WA Type) has an extremely high moment loading capacity. This will allow for single shaft designs in the most hostile environment applications.

PRE-LOAD The SER type slide guide has two levels of pre-load are available: zero pre-load and an extremely slight pre-load.

RAIL LENGTH Slide guides with most commonly used lengths are available as standard. For slide guides with a nonstandard length, unless otherwise specified, the distance from one end of the rail to the first installation hole (N) will be within the ranges listed in Tables A-16 and A-17, satisfying the following equation.

    SGL TYPE The SGL slide guide is a linear motion bearing utilizing the rotational motion of ball elements along four rows of raceway grooves. It can be used in various applications due to its compactness and high load capacity.

STRUCTURE AND ADVANTAGES Absorption of Mounting Dimensional Error:

SGL slide guides consist of a rail with four precisionmachined raceway grooves and a block assembly. The block assembly consists of the main body, ball elements, retainers, and return caps.

Because the ball elements are positioned to increase their self-aligning characteristics, the dimensional error caused during installation is absorbed.

High Load Capacity and Long Life: Anti-Corrosion Specification:

The use of larger ball elements and a raceway with grooves machined to a radius close to that of the ball elements increases the area of the contact surface. The results are load capacity and provides longer life.

The rail and block assembly may be Raydent treated to increase the corrosion resistance. This treatment is standardized with the symbol "RD", and suitable for use in clean room applications.

Low Wear: Because a 4-row/2-point contact design is used, low wear and stable motion characteristics are achieved even under a pre-loaded conditions.

Dust Prevention: Side seals are provided as a standard. To improve the dust prevention characteristics, underseals and special rail mounting caps are also available.

Omni-Directional Load Capacity: The ball elements are positioned at 45contact angle so that the load capacity is equal in four directions (above, underneath, right and left). Figure A-41 Structure of SGL type Slide Guide

TOPBALL PRODUCTS

Slide guides are generally mounted by pushing the reference surface of the rail and block against the shoulder of the mounting surface. An escape groove should be provided at the corner of the shoulder in order to avoid interference with the corner of the rail or block. The bolts used to secure the rail should be tightened using a torque wrench. The recommended torque values are listed in Table A-26.

    SGW TYPE The SGW slide guide is a linear motion bearing utilizing the rotational motion of ball elements along four rows of raceway grooves. Its low height and wide profile makes it suitable for single-rail applications.

STRUCTURE AND ADVANTAGES SGW slide guide consists of a rail with four precisionmachined raceway grooves and a block assembly. The block assembly consists of the main body, ball elements, retainers, and return caps.

Omni-Directional Load Capacity:

High Load Capacity and Long Life:

Smooth Motion:

The raceway grooves are machined to a radius close to that of the ball elements. The larger contact surface results are high load capacity and provides longer life.

The large number of ball elements produce a smooth rolling motion.

The ball elements are positioned at 45o contact angle so that the load capacity is equal in four directions (above, underneath, right and left).

Anti-Corrosion Specification: The rail and block assembly may be Raydent treated to increase the corrosion resistance. This treatment is standardized with the symbol "RD", and suitable for use in clean room applications.

High Allowable Moment: Its wide profile enables it to sustain high moment loads, making it suitable for single-rail applications.

Dust Prevention: Side seals are provided as standard. To improve the dust prevention characteristics, under-seals and rail mounting caps are also available.

BALL SPLINE ROTARY BALL SPLINE

  


   The NB ball spline is a linear motion mechanism utilizing the rotational motion of ball elements. It can be used in a wide variety of applications including robotics and transport type equipment.

STRUCTURE AND ADVANTAGES The NB ball spline consists of a spline shaft with raceway grooves and a spline nut. The spline nut consists of an outer cylinder (main body), retainer, side rings, and ball elements. Designed and manufactured to achieve a reliably smooth motion.

Transmission of Torque:

High Load Capacity and Long Travel Life:

The contact angle of the ball elements is such that a pre-load can be applied that allows zero clearance in the rotational direction, resulting in increased rigidity.

NB ball splines can sustain loads in several directions simultaneously . They can be used as a single shaft system and can transmit (or resist) torque.

Zero Clearance in Rotational Direction:

The raceway grooves are machined to a radius close to that of the ball elements. The large ball contact surface results in high load capacity and long travel life.

Ease of Additional Custom Machining: Since a round shaft with raceway grooves is used, NB ball spline shafts can be machined easily to customized specifications.

Wide Variety of Configurations: A total of 16 shafts with diameters ranging from 4mm to 100mm are available. Seven different types of nuts are available: cylindrical types (SSP/SSPM), flange types (SSPF/SSPT), and block types (SPA/SPAW/SSPB). They can be specified to suit various applications.

High-Speed Motion and High-Speed Rotation: The outer cylinder is compact and well balanced, resulting in good performance at high speed.

OPERATING CONDITIONS Figure B-4 Examples of Dust Prevention Methods

The performance of a ball spline system is affected by the operating condition and environment of the application. The operating conditions should therefore be carefully taken into consideration.

Dust Prevention: The introduction of foreign particles and dust may affect the motion characteristics and shorten the life of a ball spline. In a typical operating environment, seals work well. However, they may not prevent the entry of foreign particles in a hostile environment. When used in such an environment, the ball spline should be protected using bellows and protective covers.

bellows

cover

Excessive Moment: The allowable load for ball splines is high, and they can also sustain high moment load. However, when the load becomes excessive, the load applied to the raceway grooves becomes unbalanced and stable motion may not be achieved. When accuracy is required, the application of excessive moment should be prevented by using two or more spline nuts.

Operating Temperature: The ball retainers used in ball spline nuts are made of resin, so the operating temperature should never exceed 80oC.

BALL SPLINE ROTARY BALL SPLINE

LUBRICATION

TOPBALL PRODUCTS

Both ends of the spline nut have a side-seal as a standard feature. For the fully ground spline shaft, the side-seals are positioned against the spline shaft so as to prevent the lubricant from leaking out of the spline nut. Lithium soap grease is applied to NB ball spline nuts before shipping, so there is no need to apply lubricant at the time of installation. However, a small amount of lubricant may be lost during operation, so the lubricant needs to be replenished periodically.

MOUNTING Fit:

Table B-10 Fit for the Spline Nut

A transition fit between an SSP/SSPM-type spline nut and its housing bore is used to minimize the clearance. If high accuracy is not required, then a clearance fit clearance is used. For the SSP/SSPM type spline nuts, if only a light load is to be applied, a hole slightly larger than the outer diameter of the nut will suffice.

Insertion of Spline Shaft: Insertion of Spline Shaft: When inserting the spline shaft into the spline nut, ensure that the ball elements do not drop out. This is accomplished by aligning the raceway grooves of the shaft with the rows of ball elements in the nut. Then simply insert the spline shaft through the spline nut.

The NB rotary ball spline can be used for both rotational motion and linear motion. It can be used in scalar robots, the vertical shaft of assembly equipment, and tool changers and loaders.

STRUCTURE AND ADVANTAGES Substantial Reduction in Installation Cost:

The NB rotary ball spline consists of a spline shaft and a nut. The nut has a spline portion and a rotating portion.

The use of cross roller elements keeps the housing thickness to a minimum, making the ball spline light and easy to install.

Reduced Number of Parts: High Rigidity:

Because of the single-body construction consisting of the rotating portion which is equipped with cross roller elements and the spline portion, the number of parts is reduced and the cumulative installation error is reduced.

The cross roller elements and 4-row ball spline structure provides high rigidity in spite of the compact design.

High Accuracy: Compact and Light:

The cross roller elements ensure accurate positioning in the rotational direction.

The cross roller is directly attached to the ball spline's external cylinder, resulting in a compact and light design. Figure B-20 Structure of NB Rotary Ball Spline seal installation flange

PRE-LOAD AND CLEARANCE IN ROTATIONAL DIRECTION The amount of clearance and pre-load for the spline portion and the cross-roller portion are expressed in terms of the clearance in the rotational direction and the clearance in the radial direction, respectively. Three levels of pre-load are available: standard, light (T1), and medium (T2).

BALL SPLINE ROTARY BALL SPLINE

MOUNTING OF ROTARY BALL SPLINE

TOPBALL PRODUCTS

The flange attachment bolts have been pre-adjusted for smooth rotary movement and should never be loosened. Shock loading to the flange assembly should be avoided as this can degrade the accuracy of movement and deteriorate the overall performance.

Figure B-23 Flange mounting Method

greater than D+(0.3  1.0)

SLIDE BUSH

Mounting: When the flange is to be used with a faucet joint (as shown in Figure B-23) the housing bore should be machined to a tolerance of H7 and to a minimum depth of 60% of the flange thickness. If only a light load is applied to the SPR in operation, the flange can be used without a pilot end. When the mounting bolts are applied, they should be tightened diagonally in steps with progressively more torque at each step. A torque wrench should be used to achieve uniform torque. The recommended torque values for medium-hardness steel bolts are listed in Table B-20.

This is accomplished by aligning the raceway grooves of the shaft with the rows of ball elements in the nut. Then simply insert the spline shaft through the spline nut.

Since NB rotary ball splines are equipped with seals at both the spline portion and the rotational portion, the lubricant is retained for an extended period of time. Lithium soap grease is applied prior to shipment, so they can be used immediately without having to apply lubricant. Lubricant should be added periodically and depending on the operating conditions.

SLIDE SCREW

A grease fitting is pre-installed as a standard feature, however, an oil lubricant should be used for highspeed applications. Contact NB for further details.


OPERATING ENVIRONMENT Dust Prevention:

Certain operating environments may prevent the full functionality of the rotary ball spline from being achieved. The operating environment should be taken into consideration when designing the system.

The invasion of foreign particles and dust may affect the motion characteristics of the rotary ball spline and shorten the travel life. Seals will perform well under normal operating conditions, but may not completely prevent the entry of dust in a hostile environment. When used in such environments, a dust prevention mechanism such as bellows or a cover should be used to protect the rotary ball spline.

Operating Temperature: Resin retainers are used in the rotary ball spline, so the operating temperature should never exceed 80.

   NB now offers a new standard in linear motion with TOPBALL. The TOPBALL slide bush is a high performance bushing with three times the load capacity, capable of providing up to 27 times normal travel life of a conventional slide bushing. TOPBALL is available in a variety of configurations to fit various service conditions. NB's self-aligning TOPBALL can be designed into many different applications such as factory automated equipment, machine tools, industrial machines, electrical equipment, optical and measuring instruments. In the early stages of NB's development of TOPBALL, careful thought and consideration was given to such factors as quality, cost, performance and interchangeability. The results of these efforts are reflected in the TOPBALL features.

TOPBALL FEATURES 1. Increased Load Capacity:

4. Floating Integral Wiper Seal:

NB's uniquely designed ground load plate provides circular arch contact to the ball element resulting in a greater dispersion of the load, enabling TOPBALL to provide three times the load capacity of conventional slide bushings.

NB's unique floating seal design allows for selfalignment while maintaining equal and constant contact to the shaft. Seals do not add to the overall length of the bushing allowing for more compact designs.

2. Longer Travel Life:

5. Clearance Adjustable:

Dispersed stress on the load plate provides TOPBALL up to 27 times the travel life of conventional slide bushings.

TOPBALL load plates are designed to "float" in the outer sleeve which allows for clearance between the ball elements and shaft to best suit application requirements.

3. Self Aligning Capability: Load plates are thinner at the ends to provide a pivot point at the center of the plate. The center acts as a fulcrum to compensate for any slight misalignment between the shaft and the housing bore that might be caused by inaccurate machining, mounting errors or shaft deflection.

6. Cost Effectiveness:

Figure C-1 Illustrating circular arch design and ground surface raceway

Figure C-2 Illustrating floating seal and self-aligning feature

TOPBALL's higher load capability and longer travel life enables the use of smaller components such as bushings, housings and shafts, reducing material cost and the overall cost of the system. Longer travel life also extends replacement periods and reduce maintenance cost.

RATED LIFE The life of a slide bush can be easily calculated with the load rating of the bush, shaft hardness and applicable load. However, in many cases, slide bushing failure may be caused by improper design of peripherals, including the shaft and housing, inappropriate mounting or improper operation. Serious consideration of these peripheral factors, in addition to load rating, are highly recommended when designing a slide bush application. Basic Dynamic Load Rating and Life Expectancy: The basic dynamic load rating is the load which allows a rating life of 50km, without changing its magnitude and direction. The rating life can be obtained from the following equation.

 

C 3 L =  50 Equation (1)  P

Figure C-3 shows the relationship between rating life (L) and load ratio(C/P). In the practical use of a bushing, other factors that affect the life, such as shaft hardness and load condition should be considered. The equation for calculating bushing life considering these additional factors is:

TOPBALL PRODUCTS

Examples of Calculations:

When calculating the bush load, it is necessary to accurately obtain weight, inertial force based on speed, moment load and each transition as time passes. However, it is difficult to calculate those values accurately because reciprocating motion involves the repetition of starts and stops as well as vibration and inpact. A more practical approach is to obtain the load coefficient by taking the actual operating conditions into account.

BALL SPLINE ROTARY BALL SPLINE

Load coefficient (fw):

SLIDE GUIDE

  


Basic Static Load Rating: If a slide bush is loaded when it is in a stationary condition or working at a low speed, a permanent elastic deformation is formed on the rolling element. The deformation prevents smooth movement of the bushing. To eliminate this possibility, the basic static load rating must not be exceeded. Table C-2: Optional Load Positions

Relation Between Ball Circuits and Load Rating:

NUMBER OF ROWS

The load rating of a slide bush varies according to the loaded position on the circumference. The value in the dimensional table indicates the lowest load rating with the load placed on top of one ball circuit. If the slide bush is used with two ball circuits loaded uniformly, the value will be greater. Table C-2 shows the load ratio for the number of ball circuits in each case.

An appropriate clearance between the slide bush and shaft is required in TOPBALL operation. Inadequate clearance may cause early failure and/or poor, rough movement. Proper clearance is determined by shaft diameter and housing bore. Table C-3 and C-4 shows NB's recommended tolerances of the shaft and housing bore in order to maintain the appropriate clearance.

SLIDE BUSH

  


   The NB slide bush is a linear motion mechanism utilizing the rotational motion of ball elements. Since linear motion is obtained using a simple mechanism, the slide bush can be used in a wide variety of applications, including transportation equipment, food processing equipment, and semiconductor equipment.

STRUCTURE AND ADVANTAGES Selection According to Environment:

The NB slide bush consists of the outer cylinder and a ball retainer that guide the circulation of the ball elements, resulting in smooth linear motion.

Standard and anticorrosion NB slide bushes are available. Additionally, options available are both metallic retainers suitable for use in harsh environments and low acoustic, low-cost resin retainers. These options can be specified according to application need.

Compact Mechanism: The NB slide bush uses a round shaft for the guide, resulting in effective space utilization, which allows for compact designs.

Compatibility: A Wide Variety of Shapes and Installation Methods:

The NB slide bush is fully compatible with a variety of shaft types.

The NB slide bush is available in various shapes, which make it suitable for various types of installations : lightweight, standard, clearance adjustable, open, flange, and double-wide types.

Low Friction: The raceway surface is precision ground. Since the contact surface between the ball elements and the raceway surface is minimized, the NB slide bush provides low friction when compared to other linear motion mechanisms.

STROKE BUSH SLIDE ROTARY BUSH

Table D-7 Direction of Load and Basic Static Load Rating

SLIDE UNIT

In the open type slide bush, an opening is provided to allow the shaft to be supported from underneath. When a load is constantly applied in the direction of the opening (for example, when used with a vertical shaft or when an overhang loading is applied), the rated load decreases due to the reduction in the number of rows of ball elements that are loaded. Therefore, the load rating must be calibrated at the time of design based on the direction of the loading.

SLIDE WAY SLIDE TABLE GONIO WAY

Ensure that all burrs are removed from the shaft and carefully insert the bush by aligning it with the center of the bore. The ball elements may drop out if excessive force is used during insertion. When two or more shafts are used, the parallelism of the shafts will greatly affect the motion characteristics and life of the slide bush. The parallelism should be adjusted by moving the slide bush back and forth the length of stroke to check for freedom of movement before final fixing of shaft.

STROKE BUSH SLIDE ROTARY BUSH

When inserting a slide bush into a housing, carefully insert it by using a jig to apply a uniform pushing force at the end of the outer cylinder, as illustrated in Figure D-7. Motion performance may be diminished if an excessive force is applied to the resin portion of the outer cylinder, the side-ring, or the seal.

The normal clearances listed in Table D-8 are generally used for the NB slide bush. The transition fit is used to reduce clearance and increase accuracy. Matching the clearance as specified between bush and shaft is also possible. The pre-load for the clearance adjustable and open type slide bush must be adjusted carefully so that excessive pre-load does not exceed limits, based on the radial clearances listed in the table.

LUBRICATION Figure D-8 Example of Mechanism for Applying Lubrication

For a slide bush to continue operating accurately and have a long life, it must be lubricated on a regular basis. Anti-rust oil is applied to NB slide bush prior to shipment. When slide bushes are delivered, they should be cleaned with kerosene and dried, then a lubricant should be applied before usage.

housing

lubrication fitting

Grease Lubricant: Grease should be applied to the internal components of the slide bush. Grease should be periodically reapplied depending on the operating conditions. Reapplication may be done by adding the grease directly to the internal components or by using a mechanism similar to that as shown in Figure D-8. Lithium soap grease is recommended. A special low dust generating grease for use in clean rooms is also available. Contact NB for further details.

Figure D-9 Oil Hole (Custom Specification) oil hole

Oil Lubricant: Oil can be applied directly to the shaft or by using a mechanism similar to that shown in Figure D-8. Turbine oil (ISO standard VG32-68) is recommended for highspeed applications. Lubrication oil holes can be fabricated (see Figure D9) in the center portion of the outer cylinder to simplify oil application. Contact NB for further details.

Dust Prevention Figure D-10 Example of Dust Prevention

If foreign particles such as dust or grinding chips are introduced into the slide bush, they will disrupt the smooth circulation of the ball elements. The NB slide bush is available with seals as an option. Bellows or protective covers should be used under harsh environmental operating conditions.

A felt seal may be used when lubrication is used with the NB slide bush. This felt seal improves the effect of the lubrication and increases the period between reapplications.

The NB slide bush is a precision device and therefore should always be handled with care. The slide bush is not designed for rotational motion. When applications require both rotating and linear motions, a stroke bush (page F-2), slide rotary bush (page F8), or rotary ball spline (page B-32) should be considered.

   A wide variety of linear motion slide units are available. Their high precision blocks increase the accuracy of machinery and other equipment. The blocks can be constructed of resin to reduce cost and weight. The use of standard shaft end supports and shaft support rails simplifies the components. The use of commercial units help to reduce design time and installation and component costs.

The NB stroke bush is a linear and rotational motion mechanism utilizing the rotational motion of ball elements between an outer cylinder and a shaft. It is compact and can with stand high loading. The retainer is made of a light metal alloy with high wear resistance. Smooth motion is achieved under high-speed and high-acceleration conditions. Although the linear motion is limited to a predetermined stroke distance, the smooth combination of linear and rotational motions is achieved with very little frictional resistance. The NB stroke bush may be conveniently used in a variety of applications.

STRUCTURE AND ADVANTAGES  High Precision High-carbon, chromium-bearing steel is used for the outer cylinder. It is heat treated and ground to achieve high rigidity and accuracy.

The retainer in the NB stroke bush positions the ball elements in a zigzag arrangement. The inner surface of the outer cylinder is finished by grinding, resulting in the smooth motion of the ball elements. Each of the ball elements is held in a separate hole and smooth motion is achieved for both rotational motion and linear motion. The retainer moves half the distance of the linear motion, therefore, the stroke distance is limited to approximately twice the distance the retainer can travel within the outer cylinder. The actual travel distance should be limited to 80% of the travel distances as listed in the dimensional tables.

 Ease of Mounting/Replacement The highly accurate fabrication of the NB stroke bush results in uniform dimensions, facilitating parts replacement and housing fabrication.  Light Weight/ Saving of Space The use of an aluminum alloy for the retainer and the thin-wall outer cylinder make the NB stroke bush light weight and compact.  Lubrication Lubrication holes are provided on the oil grooves of the outer cylinder, making it easy to lubricate the NB stroke bush.

TOPBALL PRODUCTS

The accuracies of the NB stroke bush are stated in the dimensional tables. Since the outer cylinder deforms due to tension from the retaining ring, the dimension of the outer cylinder is an average value at points P, where calculated using the following equation:

  NB's RK type slide rotary bush is a highly accurate rigid component providing smooth continuous linear and rotational motion. Its structure imposes no constraints on either motion. It is much more compact than a standard slide bush with separate rotational bearing.

STRUCTURE AND ADVANTAGES 1.A smooth unlimited linear and rotational motion is obtained.

The RK type slide rotary bush uses a retainer similar to that used in the SR type stroke bush. This retainer provides the results of smooth rotational motion. The SM type slide bush is also used providing the smooth linear motion. Large ball elements are used enabling the bushing to withstand high loads.

2.There is no need to machine separate housing. 3.High accuracy is ensured for extended period of usage. 4.Its high compatibility eliminates replacement problems. 5.High rigidity enables it to withstand an unbalanced load and high load capacity.  For best performance, please select tolerance of h5 for the shaft.

SLIDE BUSH

  


  

The NB slide shaft is used with bearings such as a slide bush in order to obtain highly accurate linear motion. When used in combination with a slide bush, the shaft performs as the inner race of the bearing system. The quality and accuracy of the shaft directly affect the performance of the slide bush. NB slide shaft is manufactured with an emphasis on quality and accuracy to ensure stable functionality under many operating conditions. Superior performance is guaranteed for both rotational motion and combined rotation and linear motion.

ADVANTAGES Advanced Machining Technology:

Surface Roughness:

NB will perform a wide variety of highly accurate machining processes to provide custom shafting from relatively simple machining, such as tapping and shaft stepping to the more demanding high-speed rotating shafts and spindles. NB can also perform special grinding and bore machining requirements.

Precision grinding results in a surface roughness of less than 0.4 Ra.

Wide Selection of Shaft Types: SN type SNS type SNT type Tapped shaft type (SNB/SNSB type) Fine shaft type (SF/SNSF/SNTF type) SNW/SNWS(Inch type) SNW-PD/SNWS-PD(Inch type pre-drilled shaft)

Excellent Wear Resistance: High wear resistant carbon-chromium bearing steel (SUJ2) and Martensite stainless steel (equiverent to SUS440C) materials are most commonly used. These materials are annealed and tempered to achieve a reliably uniform hardened layer in both the circumferential and axial directions. A cross-sectional photograph illustrating the hardened layer depth of the NB slide shaft is shown below.

Special requirements: NB will provide slide shafts meeting special requirements (including special shapes and materials) not already covered by the standard product line.

1. Calculate the maximum deformation of a shaft with an outer diameter of 30 mm and a span of 500 mm when a concentrated load of 980 N is applied at the mid-point of the shaft (neglecting the weight of the shaft).  support-support : From the given conditions, P is 980 N and  is 500 mm From Table G-5, C for an outer diameter of 30 mm is 2.54 x 10-12 (1/N mm2). Substituting these values into the corresponding formula in Table G-4, max = P3C = 0.31 mm.  fixed-fixed : Substituting the values into the corresponding formula given in Table G-4, 1 max = P3C = 0.08 (mm) 4 2. Calculate the maximum deformation of a shaft with an outer diameter of 60 mm, an inner diameter of 32 mm, and a span of 2000 mm due to its own weight. From Table G-6, C for an outer diameter of 60 mm is C = 1.73x10-13 (1/N mm2) The mass per unit length of a shaft with an outer diameter of 60 mm and an inner diameter of 32 mm is 15.9 kg/m. Therefore, a uniformly distributed load of 0.156 N/mm is applied. Substituting these values into the most appropriate formula for your application given in Table G-4. 5 max =  p4C = 0.27 (mm). 8

A larger diameter shaft can overcome problems in maintaining precision functionality when a high or unbalanced load is applied. The application of the center-lined tapped shaft together with the SA type support base is ideal in such cases (see SA dimensional table on pages E-32 and E-33). The center-lined tapped shaft is standardized to simplify selection.

THERMAL-SPRAYING CERAMIC-COATING SPECIFICATION

ADVANTAGES: Parts that require wear and corrosion resistance may be thermal-sprayed with a ceramic material per NB's ceramic-coating specifications. Material so treated may be used in a wide variety of applications. The pores in the coated layer result in good lubrication characteristics and can be sealed to achieve high corrosion resistance.

APPLICATION EXAMPLES:

Application of a ceramic coating to oil-sealing parts, rollers, and shafts results in good lubrication and high wear/corrosion resistance characteristics. Note: Ceramic coated surface cannot be used as the inner race for a slide bush.

REFERENCE: Standard Coated Materials High-carbon chromium bearing steel (SUJ2) Chrome molybdenum steel (SCM415, 435) Carbon steel for machinery (S45C)

Martensite stainless steel (equivalent to SUS440C) Austenite stainless steel (SUS303, 304) Steel alloy for tools (SKS3, SK4)

   The NB slide way is a non-recirculating linear motion bearing utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required.

STRUCTURE AND ADVANTAGES High Rigidity and High Load Capacity:

The NB slide way consists of precision ground track bases and caged rollers. Precision rollers are used as the rotating element. Since they do not recirculate, there is less frictional resistance fluctuation. Additionally, there is little or no difference between the static and dynamic frictional resistances.

Since the rollers provide a larger contact area compared with ball elements, there is less elastic deformation. Additionally, since the rollers do not recirculate, the effective number of rotating elements is large, resulting in high rigidity and high load capacity.

Suitable for Minute Motion: Low Noise:

Because the frictional resistance is extremely small and there is little or no difference between the static and dynamic frictional resistances, the NB slide way is well suited for minute motion. It can follow minute motion accurately, resulting in highly accurate linear movement.

The use of a roller cage prevents noise from being generated by contact between the rotating elements, resulting in quiet operation.

All Stainless Type Available: The anti-corrosion SVS/SVWS slide ways have all stainless-steel components, making them ideal for use in clean room applications.

Low-Speed Stability: Since the frictional resistance fluctuation is small even under low-load conditions, stable motion is obtained from low to high speeds. Figure H-1 Slide Way Structure

SLIDE UNIT

The SVW type slide way consists of two R type roller cages, two SV-type rails, and one W type rail with Vshaped grooves on both sides. The use of a W-type rail results in a compact design. The SVWS type is also available with all stainless steel components.

The SV type slide way consists of two R type roller cages, which have precision rollers in a cross arrangement and four rails having V-shaped raceway surfaces. The all stainless-steel optional feature makes it suitable for use in corrosive environments.

LUBRICATION AND DUST PREVENTION Lubrication:

Figure H-10 Use of Cover to Prevent Dust

NB slide ways are lubricated using lithium soap grease prior to shipment, so they can be used immediately. Periodic application of a similar type grease is recommended depending on the operating conditions. cover

Dust Prevention: Dust and dirt can affect the accuracy and life of a slide way. A slide way used in a hostile environment should be protected with a cover (Figure H-10).

NOTES ON OPERATION Inaccurate pre-load adjustment may reduce the motion accuracy, resulting in skewing and shortening of slide way life. The pre-load should be adjusted carefully.

Dropping a slide way may result in scratches or dents on the raceway surface, preventing smooth motion and affecting accuracy. Care should be exercised in handling.

Cage Slippage:

Use as a Set:

When used under high-speed, unbalanced-load, or vibrational conditions, cage slippage may occur. The stroke distance should be determined with sufficient margin, and an excessive pre-load should not be applied.

The accuracy tolerance of a slide way is designed to be adjusted within a particular set of components. If components from different sets are used, accuracy may be affected.

Knock Pin Hole:

SLIDE SHAFT

When using SVW type knock pin holes to attach a slide way, the holes on the mounting surface should be machined after attaching the W type rail. After machining, remove the chips completely and wash as required.

STROKE AND RATED LOAD When the stroke is changed, the new stroke distance must be determined and the rated load must be reestimated as follows.

Stroke:

Figure H-11 Travel Distance

When the slide way moves along the tracking base, the cage moves half the distance traveled by the slide way in the same direction. Therefore, although the applied load may be fixed on the table, the distance between the load center and cage center will change. To achieve stable accuracy, determine the stroke distance and length of the tracking base as follows: Rail length (L) When the stroke is 400mm or over

    The NB slide table is a precision table equipped with a slide way. Its high-precision and lowfriction characteristics make it well suited for use in electronics automatic-assembly machines and optical measurement devices.

STRUCTURE AND ADVANTAGES Compact and High Rigidity:

The NB slide table consists of a slide way sandwiched between an accurately machined table and a bed. Stopper is provided within the table.

Being designed compactly, the NB slide table holds the high load capacity and high-rigidity characteristics.

High Accuracy: No Need for Adjustment:

The mounting surfaces of the table and bed are precision finished to ensure high-precision linear motion, resulting in a high-performance slide way.

The table is carefully assembled so that the accuracy and pre-load are optimized, so it can be used immediately without any further adjustment.

Low Friction: Ease of Mounting:

Its non-recirculating mechanism provides stable motion from low to high speeds.

Standardized mounting holes are provided in the table and bed. High-precision linear motion can be achieved simply by mounting.

ACCURACY SLIDE SHAFT

Figure H-13 Accuracy Measurement Method

SLIDE WAY SLIDE TABLE GONIO WAY

The motion accuracy of a slide table is measured by placing indicators at the centers of the top and side surfaces of the table, as illustrated in Figure H-13. It is expressed in terms of the indicator diflections when the table is moved to the right and left under no-load conditions.

LH : life time (hr) S : stroke length (m) n1 : number of strokes per minute (cpm)

L : travel life (km) fT : temperature coefficient fW : load coefficient  Refer to page Eng. 5 for the coefficients.

NOTES ON OPERATION Careful Handling:

Cage Slippage:

Dropping a table may result in scratches or dents on the raceway surface, preventing smooth motion and reducing the life. Care should be exercised when handling a table.

The cage can slip under high-speed motion, unbalanced-loading, and vibrating conditions. The motion speed of a slide table should be kept under 30 m/min.

Dust Prevention:

Adjustment/Installation Screws:

Dust and foreign particles can affect the accuracy and lifetime of a slide table. A slide table used in a hostile environment should be protected with a cover.

The NB slide table is adjusted to achieve optimum accuracy and pre-load. The adjustment screw and tracking-bed installation screws should not be changed.

Lubrication: Lithium soap lubrication is applied prior to shipment, so a table can be used immediately upon delivery. Periodic application of a similar lubricant should be necessary depending on the operating conditions.

   The NB Gonio way is a curved SV type slide way. It is a curved motion bearing utilizing lowfriction, non-recirculating, precision cross-rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment.

STRUCTURE AND ADVANTAGES High Rigidity and High Load Capacity:

The NB Gonio way consists of hardened curved tracking bases with precisely machined V-grooves and a curved roller cage with cross-rollers. Highprecision rollers are used as the rotating elements. Since the rotational elements do not recirculate, there is less friction fluctuation, resulting in a low-frictional curved motion.

The rollers provide a larger contact area than ball elements and there is less elastic deformation. Additionally, since the rollers do not recirculate, the effective number of rotating elements is larger, resulting in high rigidity and high load capacity.

Ease of Assembly and Installation: Suitable for Minute Motion:

The rollers are retained inside a curved roller cage, allowing assembly, installation, and the handling of components simplified. A set of components consists of 4 curved tracking bases, 2 curved roller cages, and 8 end pieces. It can be assembled immediately.

The frictional resistance is extremely small and there is little or no difference between the static and dynamic frictional resistance. The NB Gonio slide way is well suited for minute motion. It can follow minute motion accurately, resulting in highly accurate curved motion.

Low Noise: The use of a roller cage prevents noise from being generated by contact between the rotating elements, resulting in quiet operation.

Accuracy of Mounting Surfaces:

Figure H-17 Accuracy of Installation Surfaces

The accuracy of the mounting should be maintained as needed for the operation. The accuracy of surfaces 1, 2, 3, and 4 (Figure H-17) directly affect the motion accuracy. They should be sufficient for the intended operation.

Procedure (refer to Figure H-18):

Figure H-18 Mounting Method (1)

(1) Remove burrs, dirt, dust, etc. from the table and the installation surfaces of the bed. (2) Apply a low viscosity oil to contact surfaces. Fix the rail   and  by tightening bolts to specified torque values (Figure G-18a). (3) Temporarily attach the rail  on curved tracking base to the adjustment side (Figure H-18b). (4) Remove the end pieces on one side of the rails and insert roller cages to the center (Figure H18c).

(5) Re-attach end-pieces. (6) Move table to the right and left (in the direction of the stroke) to position roller cages at the center of the curved rails. (7) Set an indicator at the side of the table on the reference surface (Figure H-19d). (8) Move table to one of the stroke ends and tighten the adjustment screws slightly. Figure H-19e). (9) Move table fully to the other stroke end and tighten the adjustment screws slightly. (Figure H-19f). (10) Move the table to the center and lightly tighten adjustment screws (Figure H-19g). (11) Repeat steps (8)  (10) until there is no clearance around the table. If there is no clearance, the indicator will show a minimum fluctuation value when the table is moved to the right and left. Exercise care so as not to apply an excessive amount of pre-load. (12) Repeat steps (8) (10) and tighten the adjustment screws uniformly. (13) Fix the rail . Tighten the roller cage bolts sequentially by moving the table in the same manner as for tightening the adjustment screws.

NOTES ON INSTALLATION Lubrication:

Cage Slippage:

NB Gonio slide ways are pre-lubricated using lithium soap grease prior to shipment, so they can be used immediately. Periodic application of a similar type grease is recommended depending on the operating conditions.

When used under high speeds, or unbalanced loads, or when vibration condition are present, the roller cage slippage may occur. The rotation range should be determined with a sufficient margin, and an excessive pre-load should not be applied.

Dust Prevention:

End Pieces:

Dust and foreign particles can affect the accuracy and life of a Gonio slide way. A table used in a hostile environment should be protected with a cover.

End pieces are attached to each end of the rail to prevent removal of the cage. Do not use them as a mechanical stopper.

Operating Temperature:

Careful Handling:

The operating temperature should be kept between 20oC and 110oC.

Dropping a Gonio slide way may result in scratches or dents on the raceway surfaces, preventing smooth motion and affecting accuracy. Care should be exercised in handling.

Pre-load Adjustment: Inaccurate pre-load adjustment will reduce the motion accuracy, resulting in skewing and shortening life. Careful adjustment is a requirement.

Use as a Set: The accuracy tolerance of a Gonio slide way is designed to be adjusted within a particular set of components. If components from different sets are used, the accuracy may be affected.

SPECIAL REQUIREMENTS NB can fabricate Gonio slide ways to meet special requirements, including slide ways with non-standard roller sizes, curved tracking base lengths, rotation center diameters, rotation ranges, and number of rollers. Contact NB for further information.

      NB's BG type is a compact single axis actuator which integrates a slide guide and precision ball screw. BG type offers compact dimensions and outperforms conventional positioning tables. This is made possible by a unique "U" shaped guide rail and slide block which provides multiple functions of a guide block and a ball screw nut combined into a single unit. The "U" shaped guide rail design offers a high rigid structure resistant to bending. This structural feature allows for integrated framework of machinery or equipment and may be one-end supported. Additionally, the slide block contains 4 ball circuits which delivers high load capacity, high accuracy and high rigidity. Figure I-1Structure of BG type damper

ADVANTAGES

TOPBALL PRODUCTS

Adjustment Free: The integration of the slide guide and precision ball screw eliminates complex precision adjustment and reduces installation time dramatically.

High Rigidity: SLIDE BUSH

"U" shaped guide rail provides very high rigidity despite its compact configuration and can be used for one-end supported application.

High Accuracy: Figure I-2 Ball Contact View SLIDE UNIT

BG type contains four ball circuits and four-point contact ball grooves which contributes to its high rigidity. The combination of precision ground guide rail, slide block and precision ball screw provides high positioning accuracy.

STROKE BUSH SLIDE ROTARY BUSH

Space Saving: In comparison to conventional positioning tables, the BG type allows for compact designs and dramatic space saving. The "U" shaped guide rail and integrated slide block / precision ball screw nut make this possible.

Establish an arbitrary point. From one end, position the inner block at this point and measure the stop position. Repeat the positioning and measurement process 7 times. Repeat the same process with respect to the established set point at the midpoint and near both ends of travel. Take the maximum measurement and divide the maximum difference by 2 and indicate it with either a positive or negative sign as the test results. Positioning Repeatability= 1/2{(Maximum value of n)-(Minimum value of n)}

Positioning is performed in only one direction and the resulting position is set as the reference measurement point. Calculate the difference between the length of actual travel and the commanded travel length. Continuing in the same direction (without returning to the start point) repeat this process randomly several times until reaching limit of full stroke. Express the accuracy by the absolute maximum difference. Positioning accuracy = (n)max

   The NB slide screw converts rotational motion into linear motion by utilizing the friction between radial ball bearings and a shaft. This simple mechanism eases maintenance and installation cost. The slide screw is most commonly used as transport devices in many types of machines, and is not intended for accurate positioning requirements.

STRUCTURE AND ADVANTAGES High Machine Efficiency:

The NB slide screw consists of two aluminum blocks, each with three radial bearings with a fixed angle between them. A round shaft is inserted between the two blocks, and its rotation produces linear motion determined by the contact angle between the shaft and bearings. For variable loads, the thrust is adjusted by turning the spring loaded hexagonal bolts.

The slide screw utilizes the rotational motion of the bearings and shaft to achieve machine efficiency as high as 90%.

No Lubrication Required: The bearings are pre-lubricated with grease prior to shipment, so there is no need to apply lubrication other than to the drive shaft to prevent corrosion.

Linear Motion on a Round-shaft: Excessive Load Prevention Mechanism:

The NB Slide Screw is suitable for long-stroke applications using a standard linear shaft.

When an excessive load is applied, the screw will stop due to slippage, thereby preventing accidents.

SELECTION METHOD Life:

Tightening of the bolts creates a thrust force that pushes the bearings against the shaft. This results in a constant force being applied to the bearings regardless of the load. The thrust should not be greater than required force in the application.

The rated life is expressed in terms of the number of revolutions of the drive shaft: Equation (5). The corresponding total distance traveled and life time are given in Equations (6) and (7) respectively.

Allowable Rotational Speed: Figure J-3 Mounting of Slide Screw

When the rotational speed is increased and approaches the shaft resonant frequency, the shaft is disabled from further operation. This speed is called the critical speed and can be obtained by the following equation. In order to leave a sufficient safety margin, the maximum operating speed should be set at about 80% of the calculated value. 2

INSTALLATION 5. Tighten the bolts evenly while appling a thrust force untill slippage disappears. Care should be required to avoid excessive tightning which results in shortening the rated life.

1. Clean dust from drive shaft. 2. Place shaft between upper and lower blocks. Lightly tighten hexagonal bolts until the clearance between the shaft and the bearings diminishes. 3. Temporarily attach the slide screw to the table. 4. Adjust the parallelism between the slide screw and the linear motion guides by manually moving the table forward and backward. Fix the shaft accurately after the required parallelism is achieved.

NOTES ON OPERATION  Use of a heat-treated ground shaft such as NB's

 If the slide screw and shaft are not parallel, an

unbalanced load will be applied to the slide screw. Exercise care in controlling the parallelism.

SPECIAL REQUIREMENTS NB can fabricate slide screws to meet special requirements, including screws with a special lead or a even reverse lead. Contact NB for further information.
