The cap has a seal, and the cap is connected to the guide ring at an inner diameter of the cap by a snap-in connection. The cap has a first element of the snap-in connection, and the guide ring has a second element of the snap-in connection, said elements engaging into each other in a formfitting manner. The first element is designed as a two-component part, the soft component of which engages into the second element in a formfitting manner and the hard component of which forms a reinforcement of the soft component.

Spring strut bearing

The upper carrier part has two upper rims, and the lower carrier part has two lower rims. The upper rims and the lower rims engage into one another with the result that a combined labyrinth and slip-ring seal is formed.

A clamping device includes a first clamping plate and a second clamping plate, the first clamping plate being rotatable between a released position and a clamped position in relation to the second clamping plate. The clamping device further includes a rolling body which establishes contact between the first and second clamping plates. The second clamping plate includes a clamping ramp with a contour for the rolling body so that when the clamping plates are rotated in relation to each other, the space between the clamping plates changes. The first clamping plate has a surface which forms a plane on which the rolling body rolls from the released position to the clamped position.

The linear rolling bearing for transmitting torques about its longitudinal axis has an inner profile element and an outer profile element a first circulatory channel having roller bodies and a second circulatory channel having roller bodies. Each circulatory channel having a loadbearing channel, a return channel, and two deflection channels which connect the loadbearing channel and the return channel to one another in an endless manner. The inner profile has longitudinal teeth and each circulatory channel is positioned between separate teeth. The loadbearing channel of both the first and second circulatory channel bear against the same tooth. The first and second circulatory channel can transmit torque in the same direction by changing the return channel to a load bearing channel such that there are two loadbearing channels both on different teeth.

Linear rolling bearing for the transmission of torques

A linear guide for transmitting a torque between a tubular housing, which is defined by a longitudinal axis and rotatable about the longitudinal axis, and a shaft, which is received in the housing and movable in the direction of the axis in relation to the housing, includes a bearing assembly received in the housing for support of the shaft and attached to the housing by swaging a housing portion. The bearing assembly has two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing which is retained in the housing and defines a center axis which is oriented out-of-alignment with a normal upon a longitudinal shaft axis, and the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

An electrically assisted, power steering system for motor vehicles having an input shaft () connected to a pinion shaft () by a torsionally elastic member () is supported in a steering housing () by a rolling bearing. The rolling bearing is formed as an elastic, flexible roller bearing (), whose cylinder rollers () have at least at one peripheral position an elastically deformable cylinder roller (), having a diameter that is slightly greater than a diameter of the other cylinder rollers (). In this way, an exact guidance of the input shaft () is achieved, so that the applied steering torque can be used accurately by an evaluation unit () for controlling the servo motor ().

In a linear guide for transmitting a torque between a tubular housing, rotatable about a longitudinal axis, and a shaft, received in the housing and movable in the direction of the axis in relation to the housing, a plurality of axial rolling bearings are received in the housing in surrounding relationship to the shaft. The axial rolling bearings are disposed in two radial planes in axial spaced-apart relationship, wherein the axial rolling bearings in each of the two radial planes have each two bearing members and a set of rolling bodies disposed between the bearing members. One bearing member is constructed as bushing retained in the housing and defining a center axis which is shifted parallel at an offset to a normal upon a longitudinal shaft axis, while the other bearing member has a cup-shaped configuration to define a convex surface for support by a surface area of the shaft.

A suspension strut used in a wheel suspension of an automotive vehicle, includes a shock absorber, a suspension strut bearing, and a coil spring at least partially coaxially surrounding the shock absorber and having one spring end supported by the shock absorber. The suspension strut bearing includes two plastic carrier elements, and a roller bearing positioned between the carrier elements.

A play-free radial ball bearing, includes an inner bearing ring and two outer bearing rings which are disposed in spaced-apart relationship and define a common raceway. A spring element applies an axial force on one of the outer bearing rings to thereby press the outer bearing rings resiliently against one another. The outer bearing rings and the spring element are surrounded by a tolerance ring which is made of plastic material to provide a structural unit, whereby the tolerance ring has a shoulder on one end for radially surrounding the spring element and at least one retaining lug on another end for radially surrounding the other one of the outer bearing rings.
