Abstract: A rolling bearing assembly for lengthwise movement with respect to a shaft has an outer sleeve with internal races, and a cage guiding endless rows of rolling bodies in the bore of the outer sleeve. The cage has a slit extending axially and radially therethrough, and the cage portion aligned with the slit is radially moveable, so that an entire row of rolling bodies adjacent said slit may be radially moved into a race formed in a shaft in the bearing. The sleeve may have a second slit spaced from the first slit. The second slit may be only partial, to define a region of bending, or may extend completely through the outer sleeve to define a segment, with the first slit, that is radially moveable.

Abstract: A rolling bearing for lengthwise movement between a sliding element and a rail element has a cage arranged between the sliding element and the rail element, and at least one endless row of rolling bodies in the cage. The loaded rolling bodies of each row roll between longitudinal races of the slide element and the rail element, and the cage has longitudinal guides for loaded rolling bodies and unloaded rolling bodies, as well as turnaround guides for interconnecting the loaded and unloaded guides at each end. An elastic guide element is mounted on at least one side of one of the guide tracks to resiliently urge the rolling against the guide tracks.

Abstract: The present invention is a method for the manufacture of bearing rings ruptured along an arrow-shaped partition line for antifriction bearings or similar devices. According to the invention a radial bore is introduced through the middle of the ring transversely of the bearing axis, and in the opposite end faces are introduced V-shaped notches which are displaced in relation to the radial bore in a circumferential direction. The bearing ring is supported on one end and ruptured first on that end by a force directed against the opposite end. The ring is turned over and again ruptured similarly until an arrow-shaped partition line extends from the radial bore to the notches.

Abstract: A rolling bearing for lengthwise movement along a shaft comprised of an outer sleeve having a plurality of races therein for rolling bearings, a cage being provided to guide the rolling bearings. A sealing ring is provided at each end of the assembly, the sealing ring having lips extending radially inwardly to contact the shaft. The sealing lips are thin and elastically bendable, and are mounted to enable bowing thereof into free spaces on opposite sides thereof, depending upon direction of lengthwise movement of the shaft. As a consequence, for small movements of the shaft, the sealing lips cling to the shaft and become bulged, rather than sliding along the shaft.

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.

Abstract: The present invention is a device for securing a shaft or the like in a hub, wherein an annular groove is provided on the shaft or in the hub to accommodate an elastic securing ring of round cross-section. 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.

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: 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.
