Abstract
A release bearing (1) for actuating a gearshift clutch of an automotive vehicle comprises an angular contact ball bearing (3) in which forces are transmitted from one bearing raceway to another bearing raceway at an angle of pressure .alpha. to the transverse plane of the angular contact ball bearing (3). To improve the bearing capacity of such a release bearing (1), the angle of pressure .alpha. is configured to be .gtoreq.36.degree. and <45.degree.. Friction between the balls and the raceways of the angular contact ball bearing is reduced by the fact that an osculation K.sub.AU on the outer ring (6) is .gtoreq.1.15 and an osculation K.sub.IR on the inner ring (10) is .gtoreq.1.07.
