Abstract: Release bearings for actuating a clutch are provided, and may include a bearing ring arranged non-rotatably on a sliding sleeve mounted on a transmission input shaft and a rotatable bearing ring, which interacts with a spring of the clutch. A row of rolling elements may be arranged radially between the two bearing rings and have pressure lines oriented obliquely with respect to a bearing longitudinal axis. The rolling elements may each be bodies of revolution with a circular-arc-shaped generatrix, wherein a center angle between radii bounding the circular-arc-shaped generatrix is smaller than 180°. The non-rotatable bearing ring may have a raceway shaped complementary to a shape of the rolling elements and may guide the rolling elements in an axial direction. The rotatable bearing ring may have a raceway shaped as a spherical surface with a sphere radius corresponding to the generatrix of the rolling elements.
