A thrust washer (42) has a radially directed annular portion providing a first raceway (58) and an axially directed annular flange (52). A subassembly (46) comprising a pluraiity of rollers (56), in rolling contact with the raceway, retained axially and radially in roller cage (50), has a pilot surface facing the axially directed annular flange. Friction reducing means (66, 82) 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 (46) relative to the thrust washer (42).
