Thrust washers are used in the machine, appliances, power tools, transportation conveyance, and other recreational devices that consist of different moving parts including rotating components, axles, pins, bolts, and bearings. The thrust washers are another form of flat bearings with the shape of a washer. The thrust washers resolve the axial forces and transmit the forces in the shafts. Thrust washers are economical alternatives of rolling thrust bearing. The rugged washer shaped flat bearings are used to prevent the motion of wheels and handle the radial load for thrust and axial loads. The propellor shaft and propeller-driven vessel are used to resolve the axial and linear propulsion forces for the backward and forward spinning.

What is a thrust washer?

The thrust washer is the flat type of washers that are connected between the stationary component and rotating surfaces. These types of washers are used for the support of side to side motion and axial load on the shafts. Furthermore, it prevents movement along the shaft. The thrust washers are used to provide a surface that is supported by the bearings. The thrust washers are used for the high wear applications.

Composition material

The material of the thrust washer is determined based on applications. The selection of material is determined based on temperature, load, and speed. The thrust washers are composed of different materials including brass, plastic, graphite, and stainless steel. Majority of thrust washers are composed of high and low carbon steel. The carbon steel can be of different types including thru hardened and case hardened. Thrust washers are composed of different materials with the selected composition of maintenance, price and performance. Mostly, the hardened steel shafting and thrust washer are composed of porous bronze material that contains 30% of oil by volume. The best example of a thrust washer is oilite as a self-lubricating. The thrust washer is used in the motor shaft to resolve the axial and radial forces. The variation in the standard thrust design is used to change the velocity in different levels of rpm that exceeds the normal specification of sliding such as single thrust washer. The thrust washers are capable of absorbs damping function from the rotational vibration and act as a dynamic brake.


Thrust washers are used in different applications such as transmission, pump, axle assemblies, winches, and power take-offs. The thrust washer is used in an electric motor to control the axial displacement. The propeller shaft is used to transmit the axial thrust in a forwarding and backward motion. There are tunable options are used as bearings in motion dampers. 


The thrust bearings are used to absorb the axial loads from rotating shafts. The axial loads are further transmitted towards the shaft and work in propeller rapid rotation. Another application of thrust bearing is power drills that work in the drilling process of the tough
