Abstract: A wheel bearing has inner and outer bearing rings each having a radially outwardly directed flange, and a plurality of rolling elements arranged between the rings. An annular seal has a support element affixed to the outer ring, the support element terminating in an annular elastic element of oil resistant material that is slidably engages the inner ring. A cover extends over the flange of the inner ring and has an end terminating radially spaced from a shoulder of the outer ring, to define a sealing gap. The intermediate portion of the cover defines a lubricant accumulation space.

A shoulder is provided on the hub or shaft radially facing the annular groove and the hub or shaft has an adjusting member displaceable in axial direction with a conical face axially facing the shoulder. This face together with the shoulder forms an annular recess widening towards the opening of the groove. The floor of the annular groove on the side of the adjusting member is at a radial distance from the shaft or hub at least as great as the thickness of the securing ring.

Abstract: A ball bearing adapted for axial movement on a shaft is comprised of a cage having guideways defining endless paths having axially extending portions for loaded and unloaded balls, and semicircular end portions. An outer sleeve surrounds the central portion of the bearing and defines races for balls in the endless paths. End rings on the axial ends of the bearing radially outwardly cover the semicircular quideway portions. The semicircular guideway portions have outwardly convex bottoms, and the end rings have concave recesses in their inner surfaces aligned with the semicircular guideways. The convex portions of the guideways and the concave portions of the recesses have common centers of curvature extending parallel to the bearing axis and displaced outwardly therefrom.

Abstract: The invention refers to a bearing unit for driven or non-driven wheels of vehicles. The unit incorporates an inner member (5), an outer member (1) with intermediary rolling bodies (2) and retainer (10) and seals (11). The inner member (5) is provided with a flange-like member (7) for attachment of the unit to a wheel or to a vehicle. The invention is characterized thereby that the flange-like member (7), which extends radially outside the rolling bodies (2), has recesses (14), which make it possible to mount and inspect the retainer (10) and/or the seal (11) from the exterior of the flange-like member (7).

Abstract: A rolling bearing having rolling means guided in a cage between inner and outer bearing rings, and including a groove on one side of one bearing ring accommodating a radial projection of the cage and another groove on the other side of the bearing ring having inserted therein a separately formed restraining element for axially fixing the cage with respect to that bearing ring.

Abstract: A rolling bearing assembly comprising at least a pair of race rings having confronting spaced raceways and a plurality of rolling elements in the annular space between the race rings and elastically flexible damping means comprising an elastic damping element mounted in at least one recess in the annular portion of at least one of the rings defining the raceway, said damping element projecting slightly into the area of the raceway to frictionally engage the rolling elements and provide a predetermined resistance to rolling.

Abstract: A cage for a rolling bearing is formed of a plurality of cage parts. One of the cage parts is comb shaped, having axially extending cross-pieces adapted to be engaged by another cage piece, which may be a ring. Axially extending projections with enlarged ends are provided on the cage ring, at the inner circumference thereof, engaging correspondingly shaped recesses in the other cage part, thereby to enable snapping of the cage parts together. Recesses or projections are provided on the end of each cross-piece of the comb-shaped part, for engaging corresponding projections or recesses in the side ring of the cage, thereby to stabilize the cage in the circumferential and radial directions.

Abstract: In a method and apparatus for casting or molding cages for rolling elements, two slides are provided for each pocket. The slides have an engaging, inclined surface, and are shaped to permit one of the slides to be removed by initially sliding it along the inclined surface. The other slide may thereby be moved laterally in the formed pocket, and withdrawn from the pocket. Facing slides of adjacent pockets may be joined together, with limited movement possible therein, to form a complete ring serving as a mold member.

Abstract: The invention concerns an inner ring for a rolling bearing provided with a raceway for co-operation with a number of rolling bodies.

Abstract: In a clutch release bearing assembly for a motor vehicle, the outer ring of a clutch thrust bearing has a flange engaging a radially extending flange of a housing part affixed to a sliding sleeve. This engagement permits play. An elastic ring is held fixed with respect to the outer bearing ring, and has projections extending axially from its internal circumference to engage circular surfaces of recesses of the housing. The circular surfaces of the recesses are joined by straight sections on the housing, whereby the tendency of the sliding sleeve to rotate with respect to the bearing ring effects the radial bending of the tongues, to damp such movement.
