The simplest solution is usually the best so why choose a complex component with various moving and wearing components when there is an option that does not involve any moving parts and does not require additional lubrication or other maintenance? Often, that’s just a simple thrust washer made of metal self-lubricating PTFE. In general, metallic parts thrust washer more resistant in many respects;
The mechanical-strength value of steel may be quite high, but it can still be exploited within ball and roller bearings. Additionally, the need for lubrication creates a massive disadvantage since any relative movement lacking lubrication would have to be avoided or else wear and noise would occur. High-strength metallic thrust washer, especially those optimized for friction coefficients and wear resistance, such as those from PTFE lined steel backed thrust washer , demonstrate a massive advantage in these particular areas. Also, due to the flexibility of the materials, there are solutions any special requirements, stainless steel backed PTFE thrust washer such as extreme temperatures or food safety.
The advantage is clear—a simple thrust washer as an axial bearing, consisting of a dry-running and highly wear-resistant material has tremendous benefits when compared to traditional ball thrust bearings. With simple installation and long service life, you not only save costs quickly and easily in regard to procurement, but also sustainably in the maintenance and care of the machine. At the same time, you also save weight, which can increase your energy efficiency (or, depending on the application, the ergonomics) of the entire assembly.
Metal thrust washers – maintenance-free, made of metal, self-lubricating, Resistant to wear and impact even at high loads and temperatures. Thrust washer bearings combine the advantages of many conventionally lubricated, metallic plain bearings-particularly high load capacity and dimensional rigidity-with the design freedoms of self-lubricating materials, including the ability to operate successfully well beyond the scope of conventional lubricants.
What is a Thrust Washer?
A thrust washer is a flat bearing that accommodates axial forces in rotating machines to keep the mechanism aligned along the main shaft. They can be found in a multitude of appliances, including power tools and any device that has to move, rotating parts. Their primary purpose is to provide a surface on which the thrust bearing is seated. By working with the thrust bearing to stabilize axial movements and save rotational force, thrust washers can improve the end play of an application. These thrust washers are made from a variety of materials, but the best ones are made of PFTE. While they can be made of many different metals, like porous brass, for example, PFTE provides the longest life with the lowest maintenance requirements.

Looking to build your own customizable bushing
Metal bushing material possesses a set of special features making it suitable for different applications and requirements.
Lower souring costs
Increased shaft tolerances possible
Metal composite self-lubricating material with high-quality low carbon steel as the substrate, the middle spherical sintered porous copper powder layer, the surface tie with PTFE wear-resistant lubricating material as bearing working layer, this material has excellent mechanical load capacity, The middle layer of copper powder not only in time to pass bearing the heat generated during operation, but also improves the plastic layer and substrate bonding strength. PTFE is designed for complete dry friction and has developed a wide range of materials based on lubrication, friction coefficient, and durability requirements. PTFE metal composite materials in the external lubrication or non-lubricating circumstances, can in the most extensive load, speed, and temperature range to provide the best performance.
Customized For Quick Learning
The bushing can also be selected according to different working conditions, such as bronze backed, stainless steel-backed, lead-free and other formulations.

- 1) "running-in" stage: the surface layer of PTFE mixture to the other side of the surface of the dual-filled surface to fill the pit, and the formation of transfer film, at this time, the friction coefficient of material wear faster. As shown in the curve Ⅰ.
2) "stable" wear stage: the friction after running into friction between the PTFE, the friction coefficient is low and stable, low wear rate of the material and stable. As shown in the figure Ⅱ area curve.
3) "abrupt" wear stage: PTFE lubricant in the pores of the porous layer is consumed, and a sufficient amount of lubricant can not be obtained between the friction surfaces. Friction between the poor lubrication, friction coefficient increased rapidly, the material wear rate has accelerated dramatically, until 70% of bronze exposed, life is close to termination.
The main factors affecting life
1) PV value
PV value is an effective index to determine bushing wear life. If the required life is extended, the PV value must be reduced.
2) Ambient temperature effects
The higher the ambient temperature, the shorter the bushing service life.
3) On the impact of dual components
With the use of alloy steel or hard chrome plated shaft, the surface roughness Ra = 0.4 ~ 0.63 range, the PTFE Bushing bearing life can be significantly improved.
