Abstract: A clutch thrust bearing has thin-walled bearing members formed to define a race therebetween for receiving rolling bearing elements. One of the bearing members has a generally radially extending central wall portion, and an axially extending annular wall portion, the center portion defining one wall of the race and the axially extending portion extending away from the other bearing member. The one bearing member further includes a second thin-walled portion on the side of the bearing away from the other member, and axially spaced from the center wall portion of the same member. This thin-walled portion has a central depression for receiving thrust loads on the bearing, and the outer walls of this portion extend axially and are telescoped with the first mentioned axially extending wall. An elastic member is provided between the two center portions of the one member, and may be in the form of a split ring or an elastic material.

Abstract: A clutch release bearing assembled with a holding ring axially fixed on a sliding sleeve, and with the outer race of the bearing encircling the sleeve; recesses in the outer race engage projections in the holding ring, thereby allowing the outer ring to have relative radial movement without relative rotational movement with respect to the sleeve, and thus permitting self-centering of the bearing on the sleeve.
