One of the first roller or pair, the second roller or pair, and the third roller or pair is mounted such that it can move in a transverse direction perpendicular to the longitudinal direction relative to the carrier, and wherein the movably mounted roller is resiliently pretensioned in transverse direction by a first spring element.

A preloading mechanism including: a first part having a protrusion; and a second part having a recess that matches the protrusion; wherein the recess includes a gib that is flexibly movable via a flexure; wherein a dimension of the recess varies based on a flexing of the gib; when the gib is in a neutral state, the dimension of the recess is smaller than a corresponding dimension of the protrusion; when the gib is in a flexed state, the dimension of the recess is larger than the corresponding dimension of the protrusion; and when the protrusion is inserted into the recess, the gib is in an interfering state, providing a preload force for eliminating a clearance between a surface of the protrusion and a corresponding surface of the recess, wherein the flexing of gib in the interfering state is between those of the neutral state and flexed state.

The present disclosure describes bearing assemblies for a mover of a linear motor system. The bearing assemblies may include a plurality of bearings, a housing that retains the bearings, a plurality of springs biasing at least one of the plurality of bearings towards a track of the linear motor system, and at least one dampening element dampening movement of one or more of the plurality of springs.

A retention apparatus, system and method of attaching items, panels or other devices to a rail formed in longitudinal lengths configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut including a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut, between an anchor latch of the rail and hook flange on the channel nut, and cooperating forces and movement of the biasing element secured to the channel nut.

A telescopic system comprising at least two profiled rails which are guided linearly on one another in the longitudinal direction, are movable relative to one another over a distance and each have a longitudinal profile with longitudinal grooves and/or longitudinal ribs wherein at least one sliding element is provided on each profiled rail, via which sliding element the at least two profiled rails bear against one another in a slidable manner, and which sliding element is arranged so as to be fastened in an axially non-displaceable manner, at least with respect to the longitudinal direction, on the longitudinal profile of the associated profiled rail. Such a telescopic system is intended to be simpler in design and able to be mounted more easily. This is achieved in that the sliding element, at least with respect to a sliding plane defined by the longitudinal direction and a first transverse direction perpendicular to the longitudinal direction, is then connected to a clamping element so as to be fixed against displacement on the profiled rail, wherein the clamping element is arranged with a clamping fit on the longitudinal profile of the profiled rail, to be precise in or on a longitudinal groove and/or on a longitudinal rib.

The invention relates to a slide for a linear guide which comprises the slide and a rail element with two running surfaces facing each other. 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 retention apparatus, system and method is useful for attaching items, panels or other devices to a rail formed in longitudinal lengths and configured with a cross-sectional profile having multiple cooperating structures between the rail and a channel nut including a recess formed between a tooth and shelf on an interior first channel portion of the rail and a flange of the channel nut, between an anchor latch of the rail and hook flange on the channel nut, and cooperating forces and movement of the biasing element secured to the channel nut.

A guide apparatus includes a track member, a movable member having a first rolling surface that forms a load rolling passage together with a rolling surface of the track member, and a damper provided on a first surface. The first surface is at least a portion of the surface of the movable member opposed to the track member excluding the first rolling surface. The damper includes a plate member disposed in such a way as to cover the first area and a reservoir space formed between one surface of the plate member and the first area. The reservoir space contains a damping medium and allows the plate member to displace relative to the first area. The damper is provided on the movable member in such a way that the other surface of the plate member slides on at least a portion of the surface of the track member opposed to the movable member.

A slider assembly (10) for a transportation system (100) for transporting an object (101) is provided. The slider assembly (10) comprises a first support (12a) and a second support (12b), a first guiding element (14a) arranged on the first support (12a) and a second guiding element (14b) arranged on the second support (12b), wherein the first guiding element (14a) is configured to receive a first rail (104a) and the second guiding element (14b) is configured to receive a second rail (104b), such that the slider assembly (10) is slidably arrangeable on the first rail (104a) and the second rail (104b). The slider assembly further comprises a tolerance compensation element (18), which connects the first support (12a) and the second support (12b), such that at least a part of the first support (12a) and at least a part of the second support (12b) are spaced apart from each other, thereby allowing a relative movement of the first support (12a) and the second support (12b) with respect to each other.

The disclosure relates to a steer-by-wire system for a motor vehicle including a steering rod, an electric servo unit configured to move the steering rod, and a sliding bearing which radially supports the steering rod in a housing. The housing, the sliding bearing, and the steering rod have complementary geometries whereby the steering rod is prevented from rotating. The sliding bearing includes multiple segments in the circumferential direction, at least one segment of the multiple segments is a sliding bearing location for the radial support. At least one segment of the multiple segments is a first supporting element configured to prevent rotation in one direction of rotation. At least one segment of the multiple segments is a second supporting element configured to prevent rotation in the opposite direction of rotation.
