Thrust washers are flat washers that are located between a rotating surface and a stationary component. They support the axial load or side to side motion on a shaft and prevent movement along that shaft. The thrust washer provides a surface on to which a bearing is supported. They are made to be used in high-wear applications.
Thrust washer material is determined by the application. Choice of material is determined by several factors such as speed, load, and temperature. Thrust washers may be produced from plastic, brass, bronze, stainless steel, graphite, or various other materials.
