Performance in Motion Allowable load of housings The allowable loading capacities of the housings differ substantially, depending on the housing shape and the load direction. Since the ball bearing units is complicated in form, it is difficult to calculate their allowable loading capacities. In many cases such values are entirely different from the actual ones. For such reason, the P type housings is taken up here as most popular example. The strenght to the load from each direction is shown here as obtained from the actual test

Allowable load pressed of housing Pressed housing shows deformation when subjected to the lead. The deformation depends upon direction and amount of the load, form of the housing, and the thickness of steel plate. Therefore, the allowable load of the housings must be such an amount that deformation of the housing may not disturbed the function. The allowable load of the plate housing is approximately 1/3 of the basic load rating in the radial direction, and approximately 1/3 of allowable radial load in the axial (thrust) direction.

Performance in Motion Lubrication of Ball Bearings Permissible Speed Permissible speed of a ball bearing is expressed normally in terms of dn value (Bearing bore diameter mm x operating speed r.p.m.), althought it is influenced by the shape, size, lubricant type, and seal device. The permissible speed can be roughly determined by the sliding speed at the friction part of the holding device and rolling body, in the case of ball bearing unit, it is provided with grease sealed by the oil seals and slingers. Accordingly, the friction resistance at seal contact yields also a large influence on the permissible speed. When such factors are taken into consideration, the permissible speed is given as follows. Dn < 150,000 [dn=dxn] Whereas: d: Bearing bore diameter (mm) n: Operating speed (r.p.m.)

Lubricant Grease Ball Bearing units adopts the lubrication mechanism by grease. Since the ball bearing itself is required high precision, the grease must be in particularly fine quality. Various, type of grease are sold in the market; each having different combination o mineral oil and metal saponification radical. Among them, lithium saponification radical grease is usually called, “Multi-purpose grease” . It is most suitable for a ball bearing unit. At present, “ Gold pillow lube” grease is used for the standard product of DPI and is lithium saponification radical grease it is most suitable for the ball bearing.
Replenishment of Grease Since the high quality grease is used for the ball bearing unit, the grease can be used for a considerable time without the grease supply, if the bearing working oondition is favorable and the operation temperature is not too high.However,even if the best quality grease is used, the quality deterioration cannot be prevented as the time passes by. When the dust or moisture surrounds the bearing too much or the bearing is subjected to the high temperature, the grease must be supplied periodically according to the grease deterioration. DPI ball bearing unit has such a construction so as to allow the grease replenishment during the use. Grease is injected into the grease nipple by use ofthe grease gun. Through the oil groove provided in the bearing outer ring and the oil hole, it is supplied to the inside of bearing. The grease supply interval is dependent on the kind and quality ofthe grease to be used as well as the operations conditions ofthe bearing. Under the normal operation condition, however,the value as obtained by the following formula is recommended.

Sealing Devices Following kinds are used as the sealing device of DPI ball bearing unit. By selecting the sealing device which is most suitable to the application condition, the bearing working life can be doubled. B-type sealing device(Applicable bearing....UC type, HC type, RB type, SER type) This is the original sealing device. Oil seal is fixed in the outer ring inner diameter groove, while the slinger is set at the inner with inner outer ring outer diameter. Furthermore, the simultaneous revolution with inner ring generates the wind pressure for dust-proof property. This constitute the ideal labyrinth. Effective dust-proof property is thus guaranteed.
L-III type sealing device(Applicable bearing....UC type, UK type, HC type, RB type, SER type) This is an epochmaking new seal. Which can be said to be a revolution in the bearing sealing. The metal cap and synthetic rubber seal are baked together to form a single seal. Seal lip has sufficient tightening allowance. Furtheremore, the lip layers are double or triple construction and the foreign matters such as dust, water, etc. are completely shut out. This sealing system shows its outstanding performance under severe ambient conditions as dust, dirty water, gas and chemicals, where is has been so difficult to be controlled.
06
Performance in Motion J-type sealing device(Applicable bearing....SA type, SB type, SC type) Synthetic rubber is adhered by baking the core piece. It is inserted into groove of the outer ring and fitted the inner ring outer diameter It has low friction, high property in oil resistance and good mechanical stability.
K-type sealing device(Applicable bearing....SA type) Special Synthetic rubber is baked at the inside of thick steel shield plate and is fixed with the outer ring of bearing. The inner ring outer diameter special synthetic rubber contacts reasonably tight so that the friction resistance will be lessened. The thick steel plate protects the rubber seal. This combined effect ensures the long service life even under considerably unfavorable conditions. Dust Proof Unit with end-covers: opened
Dust Proof Unit with en-covers: one opened, another close
Handlings One of the predominate features of DPI bearing units is their simplicity of handling and installation. It is of the utmost important that these units are handled and installed correctly to ensure reliable performance. Installation of setscrew units When Installing setscrew units, it is important to tighten the setscrews to the shaft with the specified torque. If the unit is mounted in an environment where it is exposed to impact or vibration, or if the shaft is rotated in normal and reverse directions, or if rotation is started and stopped frequently and repeatedly, then grind or drill the surface of the shaft where it is contacted by the setscrew with file or drill in order to create a flat seat (a) or drilled seat (b). This will significantly improve the tightening effect of the setsrews.

07
Performance in Motion If the unit is exposed to great load excessive vibration, another option is to use a shouldered shaft and tighten the inner ring of the bearing with a shaft nut, For dimensions of the shouldered shaft, see “9 Design of shaft and base“
Fig. c. Example of installation with a shouldered shaft and shaft nut Standard DPI bearings are equipped with double point setscrews which offer secure tightness to the shaft. Additional styles of setscrews are also available to meet a range of purposes and operating conditions (see. table A) Table A. Setscrews of the ball bearing for units
Double point (no indication)

The cone point at the center of the screw combined with the round point at the outer sdge provide excellent shaft contact and greatly reduce fitting error. A nylon film is fused to the thread surface to prevent the screw from lossening during operation Prevent looseness with elastic force of nylon film fused to the thread surface
Shown below are installation procedures for bearing units with setscrews. (1) Inspect the unit to ensure that the rigidity of the base, flatness of the mounting surface, and tolerance of the shaft meet the required standards. Check the shaft for bends, burrs and other flaws. (2) Make sure that the tip of the setscrew does not exceed the bearing bore diameter surface. (3) Fit the bearing unit onto the shaft and slide it to the specified position. In order to secure a tight fit. press -fit the bearing unit to the shaft with a press, cold -fit by cooling the shaft, or shrink-fit the bearing unit by warming with an air bath (100 °C or lease). Avoid hitting the bearing with a hammer to press-fit the bearing to the shaft). (4) Align the bearing unit to the specified position on the base and affix it with washers, if necessary, and bolts (Fig. d) Use the torque wrench to tighten the bolts to the housing to the specified torque setting. For mounting bolt torque specifications. (5) Tighten both of the setscrews on the inner ring to the specified torque setting (Fig. e). (6) Turn the shaft by hand and tighten the setscrews of all other bearings in the same shaft to the specified torque setting. (7) Finally, turn the shaft by hand and make sure that it rotates without any problems.

Performance in Motion Installation of adapter style units Adapter units, comprised of an adapter sleeve. locknut, and washer, can be installed into environments where they are exposed to excessive vibration and impact. It is of great importance that these units are properly mounted. If the locknut is not properly tightened, the sleeve may be loose which could lead to slippage and wear on the shaft or bearing.Conversely, if the locknut is over-tightened, the inner ring of the bearing can expand and reduced internal ball clearance which could cause excessive heat and premature failure.
Fig. e. Tightening of setscrew
Installation procedures for adapter style bearing are shown bellow. (1) Inspect the unit to ensure that the rigidity of the base, flatness of the mounting surface, and tolerance of the shaft meet the required standards. check the shaft for bends, burrs and other flaws. (2) Slide the adapter sleeve onto the shaft where the bearing unit will be installed. If the sleeve is to tight, place a screw driver in the slotted portion of the sleeve and expand the slot to open sleeves, (3) Slide the bearing unit over the shaft and onto the adapter sleeve, then place a cylindrical reinforcing place againts the inner ring of the front side of the bearing. Seat the adapter sleeve by lightly tapping all around the backside of the sleeve (Fig. f)
Fig. f. Fitting adapter sleeve to bearing with tappered bore (4) Attach the lock washer so that the tab fits into the slot in the sleeve, and making sure the tapered side is facing the bearing, tighten the locknut on the sleeve by hand.
(5) Align the bearing unit to the specified position on the base and affix it with washers, if necessary, and bolts. Use a torque wrench to tighten the bolts to the specified torque setting. (6) Use a torque wrench to tighten the locknut to the correct specification (Fig. g) (7a) For pillow block housings, loosen the mounting bolts and adjust the unit axially while rotating the shaft by hand. Then re-tighten the mounting bolts to the correct specification. (7b) For flange block housings, the position of the unit must be in the correct axial position in relation to the shaft, so take extra care to properly align them before completing installation. (8) Bend one of the tabs on the washer so that it fits into one of the slots on the locknut (Fig. h).

Fig. h. Bending claw of washer (Locking locknut)
(9) Finally, turn the shaft by hand and make that it rotates without any problems.
09
Performance in Motion Installation of units with eccentric locking collars Eccentric locking collar bearings provide another option for shaft locking. Since the rotating force of the shaft increases the tightening force of the eccentric ring to the shaft, this style of bearing allows a secure grip to the shaft. Since the rotating force of the shaft increases the tigthening force of the eccentric to the shaft, the unit with eccentric locking collar allows secure fixing of the bearing (Fig. i)
Fig. i. Ball bearing units with eccentric locking collar
Installation procedures for eccentric locking collar style bearings are shown below. (1) Inspect the unit to ensure that rigidity of the base flatness of the mounting surface and tolerance of the shaft meet the required standards. Check the shaft for bends, burrs and other flaws. (2) Slide the bearing onto the shaft, and place it at the specified mounting position. (3) Align the bearing unit to the specified position on the base and affix it with washers, if necessary and bolts (Fig. a). Use a torque wrench to tighten the bolts to the housing to the specified torque setting. (4) Fit the eccentric section of the inner ring of the bearing to the eccentric recessed section of the eccentric locking collar, and rotate the collar in the direction of shaft rotation. Then tighten the setscrew eccentric locking. Then tighten the setscrew eccentric locking collar to the specified torque setting (Fig. j) (5) Rotate the shaft by hand and then install the next eccentric locking collar unit to the shaft, (6) Finally, turn the shaft by hand and make sure that it rotates without any problems.
Fig. j. Installing eccentric locking collar
Installation units with covers Covers for ball bearings are available in two types, steel plate and cast iron. Install both the covers at last after installation of the bearing and housing is complete. Procedures for installation of the ball bearing units with covers are shown below, (1) Apply grease all around the seal lip of the cover, and pack the internal space of the cover with grease (approximately 1/3 to 1/2 of the space capacity). (Fig. k)

Performance in Motion (1) Put a cover through the shaft, and then, fit the bearing unit the shaft. (2) Fit the cover through the shaft to the cover groove on the housing and fix it. (4a) For the steel plate cover, tap all around the cover evenly with a synthetic resin hammer to prevent deformation and install it to the housing. (Fig.l) To remove the steel plate cover, put screwdriver into the groove on the periphery of the cover, and slightly pry it. (4b) When installing the case iron cover, fit the cover to the housing, and fix it with the bolt. (5) Install another cover to the housing in a similar manner. (6) Check for abnormality of installed cover. (7) At last, turn the shaft with your hands, and check for abnormality in the rotating status of the bearing.
Periodic Inspection
Fig. l.Installing steel plate cover
DPI ball bearing units do not not to be inspected as frequently as lower bearings. However it is good practice to set up an inspection schedule for even these high quality bearings. Since a ball bearing unit cannot be disassembled for inspection if the internal status of the components the external appearance of the bearing must be inspected to give tell-tale signs of the status and expected life of the bearing. The following characteristics must be checked per the inspection schedule that is established for a particular specification. 1. Overall appearance 2. Looseness of setscrew of bearing inner ring or ot the mounting bolts 3. Noise form vibration 4. Temperature of the bearing housing or inner ring 5. Grease supply interval and quantity of grease injected into the bearing either too much to little grease can be detrimental to the life of the bearing. Table B shows the main faults that are usually found during periodic inspections and their causes. If any fault is found in a ball bearing unit during an inspection, then immediate action must be taken into correct the situation and prevent deterioration of the bearing components. If serious damage has already occured to the bearing unit, then the bearing must be replaced immediately to prevent damage to other machine components.
