introd uction self- l ubricating bearings

The Dryslide trademark identifies a whole range of self-lubricated dry sliding bearings. A composite structure, TH consists of a carbon steel backing, an intermediate layer of sintered bronze, PTFE based sliding lining. The main items in the TH range are the wrapped cylindrical bushings (DIN 1494) and the flanged cylindrical bushings. Moreover, the range also includes thrust washers, strips and special parts made to customer specifications. From a technical point of view, the product is already widely known and new applications are constantly being identified to take advantage of the high load capacity, the self-lubricated feature and the excellent ratio between cost and performance of the whole range.

Product Structure Steel bronze powder with PTFE/Fibres mixture (Lead Free) 1. PTFE based mixture 0.01-0.03mm: provides an excellent initial transfer film, which effectively coats the mating surface of the bearing assembly, forming an 1 oxide type solid lubricant film. 2. Sintered bronze powder 0.20-0.35mm: provides maximum thermal conductivity away from the bearing surface, also serves as a reservoir for the PTFE based mixture.

3. Low-Carbon Steel: provides exceptionally high load carrying capacity. 4. Copper/Tin plating 0.002mm: provides good corrosion resistance. A dry running bearing with a low coefficient of friction, good wear properties and sliding characteristics. It can be used in both rotary and oscillating applications.

Typical Applications Can meet the demanding criteria for long life and trouble-free performance with or without lubrication. Automotive: tractors, combines, crop sprayers, earthmovers, and road graders. Specific uses in power steering cylinders, steering gear thrust washers, disc brakes, callipers, pistons, shock absorbers, governor linkage, windshield wiper motor, and tilt gear assemblies... Office Equipment: photocopy machines, mail sorters, postage meter systems, computer printers, peripheral equipment, automatic printing devices, and mail processing machinery... Hydraulics and valves: pumps including gear, rotary, water, axial piston, and other types, ball, butterfly, poppet steam, and other valves and valve trunnions... Home Appliances: refrigerators, air conditioners, vacuum cleaners, polishers, sewing machines, ovens, dishwashers, and washing machines... Materials handling: pallet trucks, scissor lifts, packaging machinery and textile equipment...

DMR THX

Introd uction Pre- Lubricating Be arings

Product Structure Steel bronze powder with Acetal Marginal bearings 1. POM (Acetal) 0.30-0.50mm: has high wear resistance and low friction. The bearing surface has a pattern of circular indents, which should be filled with grease on assembly.

The THX trademark denotes a range of sliding bearings produced from a material with a composite structure. The backing consists of carbon steel onto which a porous layer of bronze is sintered and then impregnated with a co-acetal plastic. The polymeric surface has indentations in which the lubricating grease lies and protects the mating surface. The main products in the THX range are the cylindrical bushings (DIN 1494), but thrust washers and strips are also available as well as special parts made to customer specifications.

Low-Carbon Steel: provides exceptionally high load carrying capacity. 4. Copper/Tin plating 0.002mm: provides good corrosion resistance. The THX bushing can be used in rotary and oscillating applications. Less maintenance requirements due to the long re-lubrication intervals. Less wear, less susceptibility to edge loading, and no absorption of water. The THX has good damping qualities and is resistant to shock loads.

Typical Applications Recommended for applications involving intermittent operation or boundary lubrication. Automotive: suspension joints, kingpin assemblies, automobile driving joint hinges, steering and other linkages, articulation joints, and rear chassis hinges. Machine Tools: spindles in drill, grinding, and milling machines, and ram guide plates in multi ram presses. Agricultural Equipment: gearboxes, clutch assemblies, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters... The THX bushing is especially well suited for applications where lubricant cannot be supplied continuously or repeatedly.

CHEMICAL PROPERTIES The PTFE sliding layer is resistant to most chemical products, while the corrosion resistance of TH bushing depends on the steel backing which does not oxidize when: • • • •

Immersed in water, alcohols or glycols In the presence of mineral and synthetic oils In acid substances with a pH level of > 5 In alkali substances with a pH level of < 9

Corrosion is triggered off in the case of repeated wet/dry cycles, the presence of oxygen and when the temperature exceeds 90ºC. The chemical resistance of TH bushing is improved by tinplating, but the problems of corrosion must be overcome by further protection such as special tin-plating, by sealing the bearings or by using the bronze-backed bearings (TH-B) or stainless steel-backed bearings (TH30).

THERMAL CONDUCTIVITY During operation heat is generated by the friction between the bearing and the shaft. The heat is partly dissipated by the fluids present (gas or liquids) and partly absorbed by the mating parts. Under normal operating conditions, the bearing must be able to dissipate the heat generated and not give rise to thermal dilations that may compromise the working of the two parts. Under both aspects, TH bushing performs very well as it features: Perpendicular thermal conductivity which is linked to the steel backing and the close contact of the bronze and the polymer layer. Both factors lead to a high level of thermal conductivity between the layers that enables the heat to be eliminated without causing a sharp rise in the temperature (on average + 20º to 25ºC compared to the temperature of the environment). Volumetric expansion: the increase in temperature gives rise to an expansion in the volume of the materials. Given the composition of the product, TH bushing expands in a way very similar to that of metals normally used for the housing and the counterpart. This similar behaviour prevents seizure during

20

heating and movement of the bearing in the housing during cooling which sometimes arises when plastic bearings are used.

ELECTRICAL CONDUCTIVITY TH bushing not only offers a high level of thermal conductivity, but also a high level of electrical conductivity that is perpendicular to the layers. However, this electrical conductivity only appears after the first running-in period, when the bronze starts to be exposed and comes into contact with the mating surface. The perpendicular electrical conductivity increases with the specific load applied on the bearing and with the degree of wear. Typical values of specific electrical resistance for units-surface are the following: Perpendicular electrical resistance: R = 1 - 10W x cm2

FRICTION The TH bushing sliding layer has a PTFE base that gives an excellent slide quality due to the low coefficient of friction. The amount of friction cannot be defined exactly as it is influenced by the following parameters: • • • •

Load factor p x v on the surface Operating temperature Presence of liquids and lubricants Material and finish of the mating surface

The load factor p x v is the result of the specific load p (N/mm2) and the speed v (m/s) and represents the reference parameter for checking the performance of this type of bearing. p x v being equal, the coefficient of friction decreases as the specific load increases, while the coefficient of friction increases as the speed increases.

design notes

TEMPERATURE The temperature has a very slight effect on the coefficient of friction if it remains within a range of 0º to 100ºC. Once these limits are exceeded, the coefficient of friction increases rapidly by 50% or more. It should be noted that very high temperatures reduce the useful life of TH bearings. Under equal load factors, the useful life is reduced by 80% at a temperature of over 200ºC compared to that noted at 25ºC.

LIQUIDS AND LUBRICANTS TH bearings have been designed for dry operations, but despite this, the presence of clean fluids in the working area can facilitate the dissipation of heat and prolong the useful life of the bearing. The presence of liquids, whether lubricants or other, may lead to hydrodynamic operating conditions which enable a considerable increase in the sliding speed at the same specific load. Hydrodynamic operating conditions are influenced by the following parameters: • • • • •

Sliding speed Specific load Tolerance of the mating surfaces Viscosity of the liquid Operating temperature

OPERATION IN THE PRESENCE OF LIQUIDS AND LUBRICANTS In practise, even the self-lubricated bearings (TH Series) can be used in the presence of liquids and/or lubricating fluids. In these situations, the behaviour of the bearings are modified and the following considerations apply: • The presence of a clean fluid on the bearing (whether lubricating or not) usually has a positive effect as it improves the dissipation of the heat caused by the friction and also improves the contact between the sliding surfaces. • It is necessary to the check the compatibility of the bearing with the fluid. Most problems arise with THX bearings as the acetal co-polymer is not recommended for use in water, glycols or synthetic oils with phosphoric esters. The other TH Series does not have any particular contraindications in the presence of widely used liquids and lubricants.

If in doubt and in case of special applications, it is advisable to carry out a simple test by immersing half of a sample bearing in the liquid in question. If, after two weeks, the bearing shows non signs of alteration in any part it can be considered to be compatible with the fluid. • For the TH Series of bearings, the positive effects of the presence of fluids are confirmed only if alternating dry and wet cycles are avoided. In the presence of repeated cycles, the result is a premature decline in the product compared to dry operating conditions. • For the bearings subject to lubrication, just the initial greasing may be sufficient as long as the application is subject to limited specific load and speed values.

LUBRICATION SYSTEMS In the presence of fluids and under certain speed and specific load conditions, hydrodynamic lubrication occurs. This involves a thin film of fluid being generated permanently between the mating surfaces. During a hydrodynamic regime, the coefficient of friction and the wear of the parts falls to such a level that the life of the bearing depends more on the number of stop-start operations rather than the actual running time. If a hydrodynamic operating regime is provided for during the design phase, steps must be taken to increase the clearance of the mating parts to facilitate the formation and maintenance of the separating film.

MATERIAL AND FINISH OF THE MATING SURFACE The material of the mating surface, whether it is a shaft or a shoulder, has a considerable effect on the results of the application. The metals which may corrode in the presence of humidity or pollutants, accelerate the deterioration of the mating surface. For applications with no protection, it is advisable to use stainless steel, chromium-plated steel or anodized aluminum mating surfaces. Bronze, non-anodized aluminum, phosphated or nickel-plated steel mating surfaces are not suitable. The roughness of the mating surface must be quite low to permit a good operating life. The recommended value for the best performance is 0.4mm Ra.

PV CALCULATIONS

To determine P in an application: The specific bearing load (P) is determined by dividing the bearing load by the pressure supporting area of the bearing. The units for P are N/mm2. The pressure supporting area depends on the specific geometry of the bearing, the following are formula for the most common types of bearing geometry.

The load factor PV has a considerable influence on determining the bearings useful operating life. PV is determined by multiplying the specific bearing load or pressure (P) by the sliding speed (V). Bearing materials are rated by a PV limit, with the PV limit representing the highest combination of load and speed under which the bearing material will operate. The PV unit of measure is N/mm2 x m/s.

RUNNING-IN PERIOD In order to complete the information and the calculations concerning the operating life of the bearings, consideration must be given to the operating method and the degree of wear on the bearings. The bearings have an initial runningin period during which the outer layer of the sliding surface is transferred onto the mating surface, compensating for the non-flatness of the contact and making the coefficient of friction stable.

After the running-in phase, the porous bronze layer is gradually exposed. The surface of the exposed bronze increases with the number of operating hours until it reaches 90% of the contact surface. At this point, the bearing is considered to have reached the end of its useful life. If, after the running-in period, the bronze is exposed regularly over all the contact area, it confirms that the application was correct.

APPLICATION Having calculated the life of the bushing (Lh), the engineer has to decide whether to accept or reject the data obtained. If the estimated life is not acceptable, the sizes of the bushing are modified and a new check is made following the sequence previously adopted. For a more detailed estimation of the operating life of DMR bushings and other products in the series, please complete the Application Data Sheet at the back of the catalogue and fax it to your local Daemar Technical Sales Representative. For applications that come close to the design limits, it is always advisable to carry out prototype testing.

FITTING METHODS

Press fitting is usually carried out using hydraulic, pneumatic or mechanical equipment (fig 1).

The most commonly used method for fitting the bushings is to press them into the housing. Having created the correct housing (H7), the following steps should be taken:

To fit bushings with a diameter or more than 55mm, it is advisable to use a retaining ring with a diameter that is 0.3/0.4mm larger (fig. 2)

• Chamfer the lead-in to the housing by 20° ± 5° to a depth of 1-2mm • Deburr and clean the mating surfaces • Lubricate the outside surface of the bushing before fitting it (do not apply excessive lubricant as it may cause the bushing to move about when fitted in the housing) • Check the alignment of the axes between the bushing and the housing • Where several bushings are necessary, align the butt joints • It is always advisable to use a guiding mandrel to insert the bushings in their housing

For flange bushings (fig. 3), the chamfer on the lead-in must have an angle of 45º and a depth of at least 2mm (2.55 for a bushing with a wall thickness of 2.5mm).

CHECKING METHODS

External Diameter - Test A

The main method for checking the wrapped bushings supplied by Daemar is to check the measurements of the internal and external diameters. Neither of the diameters can be checked before the bushing is fitted as an imperfect contact of the two edges leads to incorrect measurements.

To carry out this test, it is necessary to have the testing equipment as provided for by the standard (DIN 1494). The device consists of two half-shell shaped blocks in which the bushing is inserted and then pressed. The test consists of loading the outside of the bushing and measuring how much the bushing yields. If the amount of yield falls within a certain range, the external diameter of the bushing can be said to be correct.

The standard (DIN 1494) specifies the valid methods for measuring the internal and external diameters. The two methods are summarized below:

Internal Diameter - Test C The bushing to be checked is fitted in the housing corresponding to the nominal external diameter with the H7 tolerance. Once the bushing has been fitted, the internal diameter is measured and must fall within the tolerance field shown on the relevant table of this catalogue.

Fiber-Lube™ Composite Bushings The standard DMR™ Fiber-Lube™ bushings are available in two types of liners. A Teflon Fiber Liner (FW Series, see page 28) and a Taped Liner (FT Series, see page 30) consisting of bronze filled teflon. The following series of Specialty Bushings are also available in different liners and constructions: Daemar’s Fiber-Lube bushings use a fiberglass filament wound structure which incorporates an epoxy resin matrix that results in a very high strength bushing that is naturally concentric with no seam or overlap. This high strength laminate construction allows for the use of a thin wall (1/16” to 1/8”) bushing which reduces the size and weight of the assembly. The resulting composite material exhibits a very low coefficient of friction coupled with high load-bearing capacity.

DMR FW

fiber- l ube™

Product Description The DMR Fiber Wound Series bearing is a high load, low RPM bearing designed for rigorous industrial equipment applications. The bearing is manufactured by a filament winding process that results in a continuous fibreglass filament backing. This composition yields excellent mechanical properties especially fatigue resistance. The filament wound fibreglass structure uses a high strength, corrosion resistant epoxy resin as the matrix material. The high strength backing permits the use of a thin wall (1/16" to 1/8") bearing which can often reduce the size and weight of the finished bearing assembly. Our FW Series will support a bearing load of 30,000 PSI, while handling high radial and axial stresses. They resist high shock loading and impact fatigue due to their unique high strength continuous fibreglass backing. These qualities make the FW bearings ideal for high load operation in rotational and linear motion as well as in oscillation. This family of materials exhibits exceptional dimensional stability and performance predictability over wide temperature ranges (±325°F).

Product Design The high strength composite Ptfe Wear Resistant fibreglass backing permits Material Weave optimal strength and rigidity, with a modulus of elasticity of approximately 6 x 106 Exposed Ptfe Reduces Friction PSI. This property allows the FW bearing to be rigid enough to support heavy High Strength loads and pliant enough Composite Fibreglass to tolerate moderate shaft Epoxy Backing Wear Resistant misalignments without overDebris Lays In Voids stressing the bearing edges. The bearing surface is composed of a uniquely designed woven structure of PTFE filaments, which exhibit tensile strengths twenty times greater than PTFE resins. As a result, the bearing is not subject to cold flow under high

30

loading conditions. These PTFE super-filaments are also the primary mechanism for allowing the FW product to operate in a true self-lubricating mode. No secondary lubrication is necessary, even during start-up conditions, due to the film transfer self-lubrication process.

Mechanical & Physical Properties The FW bearing can withstand static loads of approximately 60,000 PSI and 30,000 PSI under dynamic loading. At these loading levels, minimum distortion will occur. For dry running applications, the maximum speed is approximately 10 surface feet per minute. This bearing's operating temperature range is ±325°F. Maximum continuous operational surface temperature for the standard formulation is 325°F, depending upon load characteristics. The bearing has been heat stabilized at these temperatures, so that little dimensional change will occur in the bearing during operation. In a free state, the coefficient of expansion of the FW Series bearing is approximately 7 x 10-6 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals.

Applications include material handling equipment, heavy-duty cranes, earth-moving equipment, construction equipment, agriculture equipment, 4 post automotive lifts, and food processing systems.

Development

Mechanical & Physical Properties

Many OEM design engineers specify a bearing design that may well have life cycle capabilities ten times over what their most strenuous applications require. With that in mind, Daemar's Fiber-LubeTM MRP bearing will perform more in line with the actual needs of today's innovative machine design. Our traditional composite bearing materials, such as the Fiber Wound Series, have less than 0.005" wear at over 1.6 million cycles. That type of wear curve can be unnecessary for 70% of most applications. These issues come together to allow Daemar to supply a bearing better matched to customers' needs, at a better price.

The Fiber-LubeTM MRP bearing can withstand static loads of approximately 60,000 PSI and 30,000 PSI under dynamic loading. At these loading levels, minimum distortion will occur. For dry running applications, the maximum speed is approximately 10 surface feet per minute.

Product Description Using the next generation of Teflon® only recently available to the bearing industry, Daemar is able to supply a composite bearing with the high tenacity PTFE mono-filaments as the primary anti-friction component in the ID of the bearing. The wear liner still incorporates small woven pockets to ensure a high degree of embeddability into the bearing surface, as well as ensuring that a high content of PTFE is pushed to the surface in the most efficient fashion possible. This allows for a quick transfer of PTFE from the bearing ID to the mating surface. Fiber-LubeTM MRP bearings are designed to minimize wear; however, the bearing wear is effected by the general operating conditions, such as speed, sliding distance and load. With intermittent rotation or oscillation, radial wear should be negligible over thousands of hours. Hard chrome plating gives excellent wear performance and protects the shaft from corrosion. Softer coatings such as cadmium or zinc are not recommended.

This bearing's operating temperature range is ±325°F. Maximum continuous operational surface temperature for the standard formulation is 325°F, depending upon load characteristics. The bearing has been heat stabilized at these temperatures, so that little dimensional change will occur in the bearing during operation. In a free state, the coefficient of expansion of the MRP bearing is approximately 7 x 10-6 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals.

Product Description The Fiber-LubeTM FT bearing is used for applications where a slightly higher surface velocity, when compared to the Fiber-LubeTM FW Series, is required. Similar to the FW Series bearing, the FT bearing is manufactured by a filament winding process that results in a continuous fibreglass filament backing composition-ensuring excellent mechanical properties (especially fatigue resistance) are attained. The filament wound fibreglass structure uses a high strength, corrosion resistant epoxy resin as the matrix material. The high strength backing permits the use of a thin wall (1/16" to 1/8") bearing which can often reduce the size and weight of the finished bearing assembly. These differences are driven from the fact that the FT bearing uses a filled PTFE resin structure as opposed to the continuous PTFE filaments used in the FW product. Two liner thicknesses are available with the 0.015" thick liner being standard and a 0.030" thick liner being available for unique applications. The 0.030" thick liner is designed for applications where boring the inner diameter might be required in order to achieve tighter tolerances in an effort to address sizing and minor misalignment conditions.

Mechanical & Physical Properties The Fiber-LubeTM FT bearing can withstand static loads of approximately 60,000 PSI and 3,000 PSI under dynamic loading. At these loading levels,

minimum distortion will occur. For dry running applications, the maximum speed is approximately 80 surface feet per minute. This bearing's operating temperature range is ±325°F. Maximum continuous operational surface temperature for the standard formulation is 325°F, depending upon load characteristics. The bearing has been heat stabilized at these temperatures, so that little dimensional change will occur in the bearing during operation. In a free state, the coefficient of expansion of the Fiber-LubeTM FT bearing is approximately 7 x 10-6 in/in/°F, similar to the coefficient of expansion for steel, and actually less than some metals.

Fiber-Lube™ Bronze Tape Applications Ideal applications include those that experience linear motion. Good examples of this type of application are rod-end bearings for both pneumatic and hydraulic cylinder assemblies. Unlike the FW bearing, the FT bearing can easily handle fabrication on the inner diameter of the bearing itself (there is no difference between products with respect to external outer diameter related fabrication). This ease of ID fabrication means seal grooves can be economically inserted. The result is a bearing that handles edge loading and exhibits excellent wear characteristics.

Product Description

Product Schematic

The Fiber-LubeTM IFR bearing offers the same inherent antifriction components that allow it to achieve the low wear characteristics of the FW and MRP series bearings. However, in comparison to these two products, the IFR bearing (for Improved Fatigue Resistance) offers a proprietary laminate structure of the bearing backing that increases the bearing's resistance to repeated stress/strain conditions.

Traditional filament wound composite bearings will tend to show fatigue failure in the form of resin shear failure in the traverse direction to the reinforcing fibres. The logical solution to this problem was to try to cross tie the reinforcing fibres together with other reinforcing fibres so as to minimize the shear stresses in the resin.

Several years ago, Our manufacturer was approached with a seemingly straightforward application for traditional filament wound composite bushings. At issue was an application that was resulting in bearing failure after just 10,000 oscillatory cycles. The pressure on the bearing was well under the design threshold (actual applied pressure to the bearing was 10,000 PSI). In response to this customer's demand, they developed an improved impact fatigue bearing that in the case of the above application increased the life of the bearing by over 50% and now Daemar can offer this product to you.

A low friction, self-lubricating composite bearing with significantly improved fatigue resistance against repeated stress/strain conditions.

PRODUCT ADVANTAGES The Fiber-LubeTM IFR bearing is the first bearing with such an optimized resin system and fibre/laminate architecture.

Because composite filament wound bearings are not isotropic materials as are metals, the Company 's FEA laminate analysis focused on what was believed to be the limiting factor: optimization of system's inter laminar shear. The Fiber-LubeTM IFR bearing offers a more than twofold increase in the impact fatigue over traditional composite bearing materials.

Product Description

Product Schematic

The Fiber-Lube™ HT bearing is a high load, low RPM bearing designed for applications where self-lubrication is desired, but conventional composite bearings will not perform at high temperatures. This product has been designed to provide excellent performance at elevated temperatures. With a glass transition temperature of over 450°F this epoxy filament wound structure exhibits superb performance over extended exposure to elevated temperatures. The bearing material is focused on applications where the bearing will be exposed to temperatures up to 450°F.

This bearing is based on the same filament wound structure as the Fiber-Lube™ FW Series bearing and has the same wear liner. The result is that the HT bearing has a high static and dynamic load capacity. The HT bearing is also inherently selflubricating through the same film transfer process as the Fiber Series bearing. The result of a higher temperature resin matrix, the same high strength filament wound backing, and the same self-lubrication process combine to make the HT bearing an ideal solution for high temperature applications.

In addition to its high compressive properties (in both static and dynamic modes), this bearing material is inherently selflubricating. The self-lubrication capability of our new material means that the use of expensive high temperature external lubricants such as polyurea grease, lithium grease, some bentone greases, as well as advanced ester based oils and complex thickening systems may no longer be necessary. The Fiber-Lube™ HT bearing creates a high strength, selflubricating journal bearing material that can offer performance enhancements over greased systems, as well as graphite impregnated bronze bushings, some iron-copper graphites, polysulfone, PEEK, and polymide bearing materials.

The Fiber-Lube™ High Temperature bearing was originated from development work the company was doing on high temperature, high RPM, high radially stressed composite materials for ring reinforced commutators. The end was replacing steel-mica rings with a high strength composite material.

Fiber-Lube™ HT Applications Fiber-Lube™ High Temperature applications are not just for elevated temperature environments but also for applications where the bearing may need to resist thermal expansion during operation. One example of this is in snowmobile clutch market. In these applications, the clutch speed goes from 0 to very high RPM's in micro-seconds (and vice versa). During this cycling, friction is rising because speed is being dramatically increased. As the friction goes up so does the temperature of the associated components. A high temperature composite bearing material can resist these expansion phenomena and as a result offer better long term wear, improved bearing durability, and less seizure opportunity than conventional metal bearing materials.
