The invention relates to a disengagement bearing (2) for clutches, having a sliding sleeve (6, 6a) which is arranged in coaxially displaceable fashion on a guide tube (4), between which guide tube and sliding sleeve there is formed a small cylindrical gap (16), and having a sealing means (20) which seals off the gap (16) between the guide tube (4) and the sliding sleeve (6, 6a). The problem addressed by the invention is that of proposing a disengagement bearing (2) for clutches, which is well protected against an ingress of dirt or water between the sliding sleeve and guide tube and, at the same time, exhibits free movement and low wear. To solve said problem, it is provided that, on at least one axial end (18) of the sliding sleeve (6, 6a), there is arranged, as sealing means (20), an elastic gaiter (22, 24) which is formed in the manner of corrugated bellows and which sealingly surrounds, at one side, the outer circumference of one end (18) of the sliding sleeve (6, 6a) and, at the other side, the outer circumference of the guide tube (4), and that said gaiter (22, 24) has an expansion range which corresponds at least to the maximum displacement travel of the sliding sleeve (6, 6a) on the guide tube (4). |
