Abstract: In a clutch throwout, particularly for automotive clutches, a self-centering clutch bearing is arranged on or in a sliding sleeve. The stationary bearing ring of the clutch bearing is connected with the sliding sleeve via an intermediate element, which features guides for the radial sliding, in two mutually crossing radial directions, of the clutch bearing in relation to the sliding sleeve.To enable the clutch bearing to slide in any radial direction and to position itself precisely centered in relation to the tongue ends of the clutch diaphragm spring, without great constraining forces, while, regardless of position, damping the relative movements of clutch bearing in relation to sliding sleeve, intermediate element is radially interlocked with the stationary bearing ring and with the sliding sleeve, in two mutually crossing directions.

Abstract: A self aligning bearing structure, especially adapted for electric motors, has an outer ring with a plastic jacket thereon. A housing for supporting a bearing has a cylindrical seat for receiving the outer ring. The plastic jacket has one annular central ridge of greater diameter, in the unassembled condition, than the seat, so that the annular ridge is compressed to substantially the compression limit when the outer ring is assembled in the seat. The plastic jacket may have a conical end to simplify assembly.

Abstract: In a throw-out bearing for a clutch, a movable element, which may be comprised of a sliding sleeve, is slidably supported on a guide element by flexible conical projections extending inwardly from the movable part to the guide element. The projections may be on the end of and the unitary part of the sliding sleeve, or they may be a part of a sleeve inserted within the sliding sleeve, or they may form a part of the fixed ring of the bearing.

Abstract: In a non-machining method for manufacturing a solid-bottomed or internally flanged bearing race, especially for rolling contact bearings, the starting material is in the form of a band. For the economical manufacture of this bearing race with an annular groove of extremely precise cross-sectional shape which reduces the wall thickness of the bearing race, and which is situated at the transition from the bottom or flange portion to the race portion, a flat roundel is first stamped from the band. Then a concentric annular groove is worked into one of the planar surfaces of the roundel, while the opposite planar surface thereof is supported on a planar supporting surface. Lastly, the roundel is deep-drawn in a die to form a bearing race having a solid bottom. The end face of the drawing punch concentrically engages the roundel's planar surface that is encompassed by the annular groove.
