Abstract: A wheel bearing assembly, preferably for trucks, includes a wheel adapter and a bearing unit, which has at least one first bearing ring and one second bearing ring, and a drive element. The wheel adapter is configured to connect the first bearing ring to a wheel, the first bearing ring preferably having at least one threaded bore to interact with at least one corresponding attachment means, preferably a screw, in order to connect the wheel adapter and the drive element to the first bearing ring. At least one rotation-securing element is provided that is configured to secure the connection between the wheel adapter and/or the drive element and/or the first bearing ring and/or the attachment means against rotation.

Abstract: A rolling-element bearing cage includes a plurality of pockets each configured to receive a rolling element, and retaining elements associated with each of the plurality of pockets, each of the retaining elements being configured to secure the rolling elements against falling out of the pockets in a radially inward direction while permitting the rolling elements to be inserted into the pockets in a radially outward direction.

Abstract: A transport-securing unit for retaining a plurality of rollers in a rolling-element bearing cage during transportation may include an annular region and a plurality of axially extending, circumferentially spaced projections extending from the annular region. Also, an assembly of the transport-securing unit, a rolling-element cage and a plurality of rollers in pockets of the rolling-element bearing cage, where the transport-securing unit is formed separately from the rolling-element bearing cage, and where the projections extend inside the cage and limit radially inward movement of the rollers relative to the cage.

Abstract: A wheel bearing assembly includes at least one hub having an axial outboard end, a first bearing installed in the hub and having an outer ring and an inner ring, and at least one seal element that seals against a radially inner surface of the first bearing inner ring in a liquid-tight manner. The first bearing is the outboard-most bearing of the wheel bearing assembly.

Abstract: A rolling-element bearing unit includes at least one outer ring, at least one inner ring, at least one cage, and a plurality of rolling elements between the outer ring and the inner ring and disposed in pockets of the cage. At least one auxiliary ring is disposed axially adjacent to the outer ring, and the cage includes connecting elements, such as radially outwardly extending lugs, for captively connecting the auxiliary ring to the cage.

Abstract: A rolling-element bearing unit includes at least one outer ring, at least one inner ring, a plurality of rolling elements disposed between the at least one outer ring and the at least one inner ring that are in contact with the at least one outer ring and the at least one inner ring and at least one auxiliary ring attached to an axial end region of the outer ring. The auxiliary ring may include a seal assembly and may be connected to the at least one outer ring with a snap fit.

Abstract: A wheel bearing unit includes an outer ring and first and second inner rings and a plurality of rolling elements disposed between the inner and outer rings. At least one of the inner rings has an annular groove formed between an axially outer end of its radially outer surface a radially outer end of its outwardly facing axial end. A seal element such as an O-ring is mounted in the annular groove, and the O-ring is configured and mounted such that a first portion thereof extends axially outwardly of the first outwardly facing axial end and a second portion of the O-ring extends radially outwardly of the radially outer surface.

Abstract: A pin for guiding a gear has a substantially cylindrical outer surface section, wherein the outer surface section comprises a substantially cylindrical rolling surface section, which is aligned and formed so as to make possible the guiding of the gear. The outer surface section further has a groove, which is formed so as to accommodate a retaining ring, wherein the groove is disposed with respect to the rolling surface section so as to make possible a guiding, directly or indirectly via the retaining ring, of a rolling-element assembly along the axial direction of the pin. In this way it is possible to provide a guiding of a gear wherein a small tolerance chain is implemented with respect to the axial position.
