ABSTRACT:
The invention concerns a rolling bearing for a release device of a friction clutch. The rolling bearing (1a) includes a rotating outer bearing ring (12) and a rotationally fixed inner bearing ring (2). Rolling elements (15) are guided in an inner space (14) between the bearing rings which is sealed by a sealing element. The inner space (14) of the rolling bearing (1a) is sealed on one side of the rolling elements (15) by a sealing element (20) and on the other side of the rolling elements (15) by a retention element (7). The sealing element and the retention element are each rotationally fixed on one of the bearing rings, and free ends of the sealing element and the retention element extend up to the respective other bearing ring of the rolling bearing (1a) to create a large axial or radial overlap which forms an annular gap (25, 26).
