  • Patent number: 4951796
    Abstract: A self-aligning clutch release bearing and carrier sleeve assembly includes a carrier sleeve which defines a first axis and a bearing adapted to be brought into engagement with rotating clutch fingers or the like of a clutch mechanism, which clutch fingers rotate about a second axis which may not be exactly coincidental with the first axis. The bearing and carrier sleeve assembly is adapted to adjust the rotation orientation of the bearing to coincide with the second axis of rotation of the clutch fingers. This bearing and carrier sleeve assembly comprises: a bearing including a generally annular thrust face for engagement with the clutch fingers and first and second annular raceways having a plurality of bearing elements disposed therebetween, one of the raceways rotating in unison with the thrust face and the other of the raceways being coupled with the carrier sleeve. A mounting arrangement is provided for grippingly engaging the second raceway for mounting the same to the carrier sleeve.
