Abstract

A release bearing includes a rolling-contact bearing having a non-rotatable outer ring, a rotating inner ring, and plural rolling members located between the outer and inner rings. The inner ring is intended to interact with an adjustment ring which has a ring flange for abutment against a disk spring of a clutch mechanism. Disposed in a support zone between the inner ring and the adjustment ring is a sliding element whereby the support zone is configured in the form of complementary calotte-shaped portions so that the adjustment ring and the inner ring are movable relative to one another for effecting a self-adjustment of the release bearing.
