<p>1. Sliding sleeve made of polymeric material for clutch release bearings comprising a hollow cylindrical hub element (1) with a radially outwards directed annular shoulder (3) on its outer peripheral face (2) and an essentially circular ring-shaped metal flange (4) bearing against the front face of the annular shoulder facing the clutch, which metal flange (4) forms the contact surface (5) for a radially displaceable bearing race of a rolling bearing and has an axially directed collar (6, 9), characterized in that the collar (6, 9) extends over at least a part of the inner and/or outer peripheral surface of the metal flange (4) and bears with radial pre-tension against an outer peripheral face (2, 10) of the hub element (1) and/or of the annular shoulder (3).</p> |
