Abstract
A thrust washer has a radially directed annular portion providing a first raceway and an axially directed annular flange. A subassembly comprising a plurality of rollers, in rolling contact with the raceway, retained axially and radially in a roller cage, has a pilot surface facing the axially directed annular flange. A bushing or rolling element between the pilot surface and the axially directed annular flange reduces friction between the pilot surface and the flange while maintaining concentricity of the subassembly relative to the thrust washer.
