The invention concerns a clutch release bearing comprising an engaging element capable of co-operating with a clutch diaphragm (29), and designed to be mounted on a manoeuvring element (2) mobile in translation under the action of a control member (6). The engaging element comprises a roller bearing (1) provided with a rotating ring (13) and a non-rotating ring (9), said engaging element being radially mobile relative to the manoeuvring element to be self-aligned by means of a radially elastic self-aligning sleeve (19), arranged in the bore of the non-rotating ring to co-operate with the manoeuvring element. The roller bearing is of the standard type comprising an outer peripheral surface and a cylindrical bore axially defined by two parallel radial surfaces, and at least a seal joint (18) mounted on one of the rings and in friction contact with the other ring, the sleeve comprising sealing means co-operating with a rotating part of the engaging element.
