Abstract
Abstract A self centering radial clutch release bearing and a supporting sleeve assembly. The release bearing comprises an inner race ring mounted about the sleeve, an outer race ring and a plurality of anti-friction bodies located therebetween. One of the race rings is mounted so as to be non-rotating with respect to the sleeve and to have a shank extending therefrom radially of the axis of the sleeve beyond the circle of rotation of the anti-friction bodies. The end of the shank lies opposite to a portion of the sleeve in a direction parallel to the axis of the sleeve. An elastic ring is mounted between the end of the shank and the sleeve.
