Abstract:
A rolling bearing for a release device of a friction clutch arranged between an internal combustion engine and a mechanical automobile transmission, the rolling bearing comprising a rotating outer bearing ring (12) and a rotationally fixed inner bearing ring (2) which are located coaxially around an actuating element (5), a radial spacing of the inner and the outer bearing rings forming an annular inner space (14) which is laterally closed by sealing means and contains rolling elements (15) provided with a friction-reducing lubricant, the inner bearing ring (2) and the outer bearing ring (12) comprising parallel support flanges (3, 13) extending perpendicular to a longitudinal axis (11) of the rolling bearing (1a to 1e), the inner bearing ring (2) being adapted to be force-locked against the actuating element (5) by a disc spring (6) arranged between the support flange (3) and a retention element (7, 77) and the outer bearing ring (12) being adapted to be force-locked on disengaging levers of the friction clutch, the inner space (14) of the rolling bearing (1a to 1e) being sealed on one side of the rolling elements (15) by a sealing element (20, 35, 40, 45, 50, 55, 60, 61) and on the other side of the rolling elements (15) by said retention element (7, 77), said sealing element being rotationally fixed on one of the bearing rings and said retention element being rotationally fixed on one of the bearing rings, the sealing element and the retention element each having free ends which are configured to correspond to a contour of a respective other bearing ring of the rolling bearing (1a to 1e) to create an enlarged axial or radial overlap which forms an annular gap (25, 26, 38, 42, 47, 51) of the rolling elements.
