A plastic snap cage for radial ball bearings includes thin-walled cup-like pocket elements spaced about the circumference and connected with each other in one piece through ribs, thereby forming pockets that are open in the axial direction to receive the balls. The radially inwardly and/or the radially outwardly extending boundary edge of the pockets is rounded in accordance with a selected rounding radius R.

Snap cage for ball bearings

The invention concerns a rolling bearing cage (,) made of a resilient plastic and comprising at at least one peripheral point, an axially extending gap (,) formed by a first cage end (,) and a second cage end (,) which is spaced from the first cage end (,), each of the first and the second cage ends (,) comprising at least one projection and at least one recess, said recess and projection having complementary shapes, and as viewed in axial direction, the recess and the projection partially engage each other, and as viewed in peripheral direction, the recess and the projection partially overlap each other. The novel cage of the invention is characterized in that, as seen in a radial top view of the gap (,), limiting surfaces (,) of the projection (,) and the recess (,) situated opposite each other in axial direction on two sides of the gap are inclined relative to end faces (,) of the cage (,) so that a dovetail profile is formed which enables the two cage ends (,) to be displaceable relative to each other in peripheral direction, so that an expansion of the cage (,) is stopped when the limiting surfaces (,) situated opposite each other in axial direction bear against each other and a compression of the cage is stopped when limiting surfaces (,) of the projection (,) and the recess (,) situated opposite each other in peripheral direction bear against each other. In this way, a cage (,) is created that allows almost no axial and no radial offset between the two ends (,) of the cage but permits an exactly defined displacement of the cage ends (,) in both peripheral directions.

Rolling bearing cage

A cage (1) for cylindrical rolling elements (5) comprising two side rings (2, 3) connected to each other by circumferentially uniformly spaced crossbars (4) so that receiving pockets (6) are formed for the rolling elements (5) is characterized in that opposing end surfaces (8) of the pockets (6) comprise projections (11) which extend inwards in axial direction and bear against end faces of the rolling elements (5) which prevents an axial offset between the rolling elements (5) and the cage (1) so that after insertion and suspension of the first rolling element (5), the cage (1) can be filled with the rest of the rolling elements (5) without their being damaged.

Cage for cylindrical rolling elements

An axial rolling bearing with a cage (2) comprising radially directed elastic projections (7, 8) on its inner and/or outer peripheral surface, which elastic projections (7, 8) bear against the collar (6, 5) of the race discs (4, 3) under all operating conditions of the bearing so that the cage (2) is radially centered, even if the shaft lifts off in axial direction.

Axial rolling bearing

A bearing assembly for supporting a shaft without play, in particular for use with a steering shaft in a steering column, includes a plurality of needle-like rollers that are circumscribed by a thin-walled, split bush for elastically loading the rollers in radial direction. Fitted about the bush is an elastic ring that applies a preload on the bush and has at least one peripheral surface formed with neighboring ridges of relatively greater radial dimension and relatively smaller radial dimension in alternating relationship.

Bearing assembly for supporting a shaft without play

An overrunning clutch comprising two concentric machine components (1,2) rotatable relative to each other and having locking surfaces (13,14) formed on their mutually facing peripheral surfaces, and, arranged therebetween, a plastic cage (4) comprising end rings (15) connected to each other by crossbars (16), pockets (17) for locking elements (3) spring-urged against the locking surfaces (13,14) being formed between circumferentially adjacent crossbars (16), the plastic cage (4) further comprising at least one radial projection (19) which engages into a recess (20) of one of the machine components (2) to prevent rotation of the plastic cage (4) relative to this machine component (2), characterized in that the radial projection (19) is arranged on a crossbar (16).
