Abstract: A roller bearing includes radially inner and outer bearing rings and rollers disposed radially therebetween. The rollers are retained by at least one plastic guide rim that is snapped into place in one of the bearing rings. An end of the guide rim which faces the rollers is provided with a metallic butting face to resist frictional wear.

Abstract: Axial roller bearing assembly for absorbing the axial forces of a steering knuckle pivotally supported on a steering knuckle bolt at the end of an axle of a vehicle comprising first and second bearing disks having spaced confronting raceways for a plurality of rolling elements. One of the disks has a sleeve-like edge, which encloses the rolling elements and the lateral surface of the second disk with play and prevents the rolling elements from escaping radially outwardly. A sealing ring made of elastic-type material is disposed between the sleeve-like edge and the lateral surface. A stop ring (27), separate from the disks (13, 16), is provided on the inner radial envelope circle of the rolling elements (15) to prevent the rolling elements (15) from escaping radially inwardly.

Abstract: A bearing unit consists of a radial bearing 1 and an axial bearing 2, the outer ring 3 of the radial bearing 1 being extended at one end in the axial direction to hold the axial bearing 2.So that the bearing unit is able to absorb large radial and axial forces and is reliably sealed off against contamination from the outside, the outer ring 3 of the radial bearing 1 consists of a solid piece of material, and the extension 3.sup.a of the outer ring 3 is provided, starting from the end surface 4, with a bore 4.sup.a to hold the axial bearing 2, this bore being sealed by a bearing housing cover 6, which rests against the end surface 2.sup.a of the axial bearing 2 and is connected to the outer ring 3.

Abstract: Roller bearing cage, especially for cylindrical roller bearings or needle bearings, which presses the rolling elements elastically in the radial direction against a raceway to prevent rippling, characterized in that, at least at one point (6), the cage (1) has notches (8) proceeding from the end surfaces (10) and a connecting part (11), which is rigid in the peripheral direction and which is located between the notches; and in that, in the peripheral direction, a recess (9), extending approximately across the width of the cage, is provided on one or both sides next to notches (8), this recess forming the boundaries of elastic sections (12).

Abstract: Means for securing a hardened roller bearing ring by means of a press fit on the softer bearing seating surface of a machine part in a predetermined axial position, comprising means defining at least one peripheral groove (6, 7, 8, 9), which has a sharp-edged transition to the surface of the roller bearing ring (2, 4) in the surface of the rolling bearing ring (2, 4) co-existing with the seating surface of the machine part.

Abstract: In a roller bearing cage which holds the set of rollers in the raceway of aninner ring to form a structural unit, the lateral rings are interrupted by slots. Webs extend between the lateral rings. In this way, the cage gives way radially, which makes it possible to push the rollers over one of the flanges of the inner ring to assemble the bearing. To stabilize the cage during operation, projections are provided on the webs, which, as needed, contact the raceway of the outer ring and secure the radial position of the webs.

Abstract: The invention concerns a roller bearing for performing swivel motions including a mechanism for synchronously guiding the roller bearing cage, including a roller bearing cage having a journal with a rotatable pinion gear flexibly and elastically mounted thereon in the direction of the circumference of the cage by a crosspiece, the pinion gear having teeth which mesh with at least one set of teeth on the bearing parts of the roller bearing. Stops are provided to limit the motion of the pinion gear.

Abstract: The invention concerns a device for synchronous guiding a roller bearing cage for a roller bearing performing swivel motions, the device comprising a roller cage and bearing parts which swivel relative to one another, the roller cage provided with a pinion gear formed on two diametrically opposed sites with curved toothed segments having different pitch circle diameters, the toothed segments meshing with the teeth of the bearing parts.

Abstract: A two-piece rolling bearing cage with cage bridges provided on at least one cage section. The bridges engage in corresponding recesses of the other cage section and connect the two cage sections together. The invention comprises a snap pin at the free end of each cage bridge, each snap pin having a broadened head section and an undercut surface. Each of the recesses accommodates a snap pin which has a corresponding contact surface for mating with the undercut surface. The head section has a front recess means and each recess has a preferably conical projection which, after assembly of the cage sections engages the front recess means of the head section.

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 multi-part plastic cage having a comb part with a plurality of axially extending webs adapted to engage a cover part, the cover part has recesses for receiving the ends of the webs, to absorb radial forces. The parts are joined by pins extending from one of the elements into recesses in the other, adapted to be joined by ultrasonic welding at positions spaced from the web ends, so that the pins are subject only to axial loading.

Abstract: An antifriction bearing cage comprising a plurality of parts centered and secured radially with respect to one another and axially secured together, wherein one of the parts includes a plurality of webs, one side of each web being terminated in a common ring. The free ends of each web include one centering spigot, each spigot having a defined outer surface converging toward a pin arranged thereon, and the centering spigot having a greater cross-section than the pin, the other of the parts being a cover part on the side thereof pointing towards the first part, having an opening for receiving the pin, a portion of the opening having lateral walls dimensioned to be engaged by the centering spigot having a correspondingly defined outer surface.

Abstract: A rolling bearing construction wherein a guide rim is secured to a ring incorporating the race for the guide rim by the interposition of a bonding film of a hardening, cross-linking resin.

Abstract: A plastic cage for a rolling bearing is formed of a comb part having rivet pins formed unitarily therewith. Recesses are provided in the cage side rings, aligned with the bridges, in order to inhibit deformation of the comb structure. The rivets are formed in the ends of the bridges, and are ultrasonically riveted in corresponding holes in the cage cover.
