The slide has a main part and a plurality of rolling bodies, and the plurality of rolling bodies are received on the main part such that the plurality of rolling bodies can roll at least on the two running surfaces or carry out a sliding movement relative to the two running surfaces. The main part defines the position of each one of the plurality of rolling bodies in a pull-out direction relative to the main part, wherein the slide additionally has two slide elements and a spring element, and each of the two slide elements is mounted on the main part such that it can move in a vertical direction perpendicular to the pull-out direction so that each of the two slide elements can be brought into frictional engagement with a respective running surface, said spring element being supported on the main part such that the spring element biases the two slide elements away from each other in the vertical direction.

A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

In a dust cover for a ball joint, one end of a ball stud is retained within a socket, the other end is fixed by fastening a knuckle having a notch portion, one end large-diameter and other end small-diameter opening portions are respectively retained to the socket and the shaft, and a plate member is retained between an inner peripheral surface of the knuckle and an outer peripheral surface of the shaft. The plate member is constructed by an annular plate member, an elastic annular seal portion integrally formed in an inner peripheral side of the annular plate member, and an elastic engagement projection in the annular plate member in the knuckle side, and engaging with the notch portion. The annular seal portion is retained in a compression manner between an annular step portion in an inner peripheral surface of the knuckle and an outer peripheral surface of the shaft.

A rail system (1) has a rail (20), a support device (10) for the rail (20), and a clamping device (40) for fixedly clamping the rail (20) in the support device (10). The clamping device (40) fixedly clamps the rail (20) in the support device (10) only in an operating situation. In the operating situation, a holding device (30) is arranged between the clamping device (40) and the rail (20) and releasably clamps the rail (20) in an installation situation in a predetermined position in the support device (10).

A bearing assembly has an inner ring with an inner diameter configured to receive a shaft. The inner ring has axial slots and at least two radial holes. A collar configured to surround the inner ring is provided. The collar has two radial holes. Each of the collar radial holes is alignable with the at least two inner ring radial holes. Each of the collar radial holes is configured to threadably receive set screws extendable from the collar through the at least two radial holes of the inner ring to engage the shaft. The collar has a radial slot and is adjustable to compress the radial slot to tighten the collar around the inner ring and the inner ring around the shaft. In the alternative, the bearing assembly may be provided with two collars—one for a set screw only configuration and another for a concentric clamping only configuration.

A retaining element for retaining a component within a receiving part, the retaining element including: a neck portion to be received within a notch formed in the receiving part; a first head portion coupled to the neck portion end and defining a first shoulder; a second head portion coupled to another neck portion end and defining a second shoulder, wherein the first and second shoulders oppose one another and are to abut first and second surfaces of the receiving part so as to engage the retaining element with the receiving part; wherein the first and/or second head portions include a retaining tab having a retaining surface, wherein the retaining tab has a receiving position for receiving the component and retaining position for retaining the component; wherein, in the retaining position, the retaining tab extends beyond the neck portion so the retaining surface abuts the component surface to retain the component.

In a rolling bearing in which one of inner and outer rings is a rotary ring and the other is a stationary ring, a fitting surface of the stationary ring fitted to a mating member is formed in first and second partial peripheral surfaces of a radially outer surface of the stationary ring which faces the mating member. The first partial peripheral surface is formed on one side in the axial direction, and the second partial peripheral surface is formed on the other side in the axial direction with respect to the first partial peripheral surface. An annular groove that restrains creep is formed between the first partial peripheral surface and the second partial peripheral surface. The annular groove has a depth that is large enough not to allow the bottom of the annular groove to contact the mating member when a radial static rated load is applied.

A bearing assembly is disclosed, comprising: an outer race and a plurality of rolling elements associated with the outer race. An inner race adapted to receive a shaft therein is rotatably disposed within the outer race such that the plurality of rolling elements are disposed between the inner and outer races. A cylindrical extension forming a plurality of tabs symmetrically arranged around the entire periphery of the extension is adapted to engage the shaft. A clamp collar that is installable around the cylindrical extension is defined by a circular wall with at least one threaded opening extending through the circular wall. The threaded member extends through one of the threaded openings to make contact with and apply a biasing force on one of the plurality of tabs towards the shaft when the shaft is disposed in the inner race to secure the inner race on the shaft.
