Abstract: A clutch release bearing having an outer cap provided with at least one extending lug is connected to a clutch release actuating element by a flat spring having a planar shank at one end adapted to be connected to the lug and a planar shank at the other end adapted to be articulatingly connected to the actuating element. The spring is bent between the end shanks in an unstressed condition wherein the shanks lie at an acute angle to each other. During assembly the spring is further bent so that its shanks lie substantially over one another and the spring is in stressed condition.

Abstract: A machine element is guided for linear movement along an I-beam by means of two endless rows of rolling elements on each side of the beam. The raceways for the roll bodies under load extend along the inner edges of the flanges of the beam, the raceways being positioned so that the force action lines on the roll bodies in the two raceways on each side of the beam converge in a direction away from the respective side of the beam.

Abstract: A clutch release bearing including cooperative inner and outer race rings with included rolling elements, and a holding ring having a first flange closely adjacent and facing a second flange of one of said rings, one of said two flanges having spiral grooves or other means for providing with a fluid hydraulic pressure between said flanges, thereby urging said inner and outer race rings together for maintaining a generally fixed axial relationship between them.

Abstract: A bearing assembly having a rolling contact bearing with an outer race extending to and affixed to a housing, and an inner race having axially extending teeth on its end faces. A driving member engages one end face, a driven member engages the other end face, and a through-bolt extends through the inner bore of the inner race for clamping the driven member, inner race and driving member together. An auxiliary assembly sleeve is connected to one of the driving or driven members and fitted over the through-bolt, the sleeve being in friction-tight engagement with the inner bore of the inner race.

Abstract: A self-centering clutch thrust bearing with a resilient ring between the bore of the bearing and a sliding sleeve for damping radial play therebetween.

Abstract: A clutch disengagement device having an antifriction bearing connected for radial movement on a sliding sleeve by a centering ring. The centering ring, which is fastened to the nonrotating bearing race, is fastened to the sliding sleeve by at least one clamp which surrounds a radial flange of the sliding sleeve, or of the centering ring, with radial play.

Abstract: A water pump for motor vehicles having a pump wheel arranged at the end of a shaft. A belt driven pulley is connected to the shaft for rotating the shaft and a bearing journals the shaft. The bearing has a fixed race, a rotatable race and two rows of roll bodies located therebetween. The shaft and the pulley are integrally connected to the rotatable race and the pulley has a rim for receiving a drive belt extending about the bearing so that the line of application of the force acting on the bearing lies between the two rows of roll bodies.

Abstract: A friction clutch assembly with a clutch release bearing for use with automotive vehicles. The friction clutch is provided with a disc-shaped spring release member having a central bore. The clutch release bearing is formed as a conventional anti-friction bearing having an outer race ring extending through the central bore of the release spring. One end of the outer race ring is formed with an annular flange extending substantially radially outward to contact the exterior frontal face of the spring release member. An angularly-shaped retaining ring is fixed to the portion of the outer race ring extending through the bore and is formed with an axially extending shank wall terminating in a peripheral edge which presses against the opposite interior frontal face of the spring release member.
