ABSTRACT:
A composite release sleeve includes a first cylindrical sleeve of a non-metallic material, and a second cylindrical sleeve of a metallic material. The composite release sleeve enables translation movement of a bearing such as a clutch release bearing, upon a guide element such as an input shaft. Preferably, the first cylindrical sleeve material is a polymer composite having a molded-in second cylindrical sleeve such as a bronze bushing. An integral flange extending outwardly from one end of the first cylindrical sleeve transfers the axial motion of the release sleeve to the clutch assembly. The first cylindrical sleeve further includes an integrally molded cavity which serves as a lubrication reservoir to reduce friction and facilitate slidable movement of the composite release sleeve along the input shaft.
