KRP3206 IEP Thrust Washers



Thrust washers are used as a bearing surface for rotary applications. They are made of a number of different materials according to the application. They can be made of steel, bronze, plastic or other materials with low friction coefficients. Thrust washers are sometimes called rotary thrust washers and are designed to prevent movement along the axis of a shaft. Precision engineered thrust washers are use in high wear applications such as engines, pumps and axle assemblies. Graphite thrust washers may be used in high temperature applications. Thrust washers are used to control end play in the crankshaft. End play is important because it limits the fore and after movement of the crankshaft in the block. If an engine is assembled with too much end play in the crank the forward movement of the crankshaft can destroy the main bearing caps and block.

Characteristics of Thrust Washers

Thrust washers differ from standard washers or spacers because they must carry a bearing load and not wear out over time. To perform, thrust washers must be heat treated and then polished to achieve a hardness and surface finish that is equal to the bearing that is being supported. These flat, disk shaped bearings share many of the same properties as cylindrical plain bearings such as excellent wear resistance and low friction coefficients. They are designed to support heavy axial loads and are used where axial load are expected. They allow parts to rotate while absorbing an axial thrust.

Benefits of using KRP3206 IEP Thrust Washers

These units are specially designed by the manufacturer to work on a particular make and model of engine. They run on a thin film of oil just like the engine bearings but they cannot support nearly as much load. They have been designed rather to stop lateral movement and not necessarily to support the rotating components in the engine which is the purpose of the main engine bearings. The materials and construction of the thrust washer has been selected and designed for use in a specific engine.   Contact IEP Power Products today to order KRP3206 IEP Thrust Washers.
