Clutch release bearing with a cage with axial retention

摘要

The clutch thrust bearing has inner (1) and outer (5) rings pressed from sheet metal, each ring having a race (2, 5b) in the shape of a section of a torus, and a row of balls (3) in a cage (8) between the two rings. The cage is shaped to limit the axial movement of the balls in one direction and has an axial stop which engages with an edge (18) of an annular groove (17) in the inner ring to limit its axial movement in the other direction. The races on the two rings are situated on opposite sides of a plane passing through the axes of the balls. The bearing also has a seal (9) which tends to hold the balls and the cage in an axial direction.
