Thrust Washer Bearings: Axial load management made simple.
Thrust washers can be found in almost every appliance, machine, transportation conveyance, power tool, and recreational device that has moving parts, axles, bolts, pins, bearings, and rotating components. In their simplest form, thrust washers are long-wearing flat bearings in the shape of a washer that transmit and resolve axial forces in rotating mechanisms to keep components aligned along a shaft. Thrust washers are an economical alternative to rolling thrust bearings whenever forces velocities are moderate.
Thrust washer bearings work by reducing friction between two surfaces that move against each other. When axial loads are applied, the rolling elements in the bearing move between the raceways on the shaft and housing washers, distributing the load evenly and reducing friction. This allows the two washers to move smoothly against each other without wearing out.
