The carrier base (20) has a first carrier side plate (122) and a second carrier side plate (124) at left and right sides thereof, the first carrier side plate (122) and the second carrier side plate (124) include the carrier roller (30) and the rolling member (40), respectively, and the carrier roller (30) and the rolling member (40) are configured to be rolled on the track base (10).

The invention relates to a vehicle seat with a roller guide, wherein the roller guide has at least one at least partially laterally open guide rail and at least one running roller rolling in the guide rail and connected to parts of the vehicle seat by means of at least one axle, wherein the guide rail comprises a roller bottom-side inner wall arranged parallel to a central axis of the running roller, extending parallel thereto a roller top-side inner wall and a roller outer-side inner wall arranged perpendicularly to the central axis, wherein at least one lower transition inner wall is arranged between the roller bottom-side inner wall and the roller outer-side inner wall and at least one upper transition inner wall is arranged between the roller top-side inner wall and the roller outer-side inner wall, wherein the transition inner walls are configured free from a right-angled portion and in directions from the roller top-side inner wall and the roller bottom-side inner wall towards the roller outer-side inner wall are configured with a continuously reducing spacing from the central axis of the running roller, wherein on an axial loading of the roller guide in the direction of the central axis of the running roller, a lower portion of an outer end portion at a first end of the running roller configured to face the roller outer-side inner wall lies with contact against the lower transition inner wall.

A transport system has a mobile carriage for transport of products along a guide path that has a first guide profile and a second guide profile. A first pair of rollers is mounted rotatably on a first rotation shaft borne by the carriage, so as to engage the first guide profile. A second pair of rollers rotatably mounted on the second rotation shaft engages the second guide profile. For each roller of the first pair of rollers and for each roller of the second pair of rollers, a reinforcing element is provided which is friction-coupled to at least a part of the main portions of external lateral walls of the rollers.

A contact member for a slidable carriage comprises a pair of roller bearings mounted at a contact side of the contact member and oriented to roll along a sliding direction of the contact member, and a pivot support surface to engage a counter surface structure of the slidable carriage.

A module bearing and a power transmission device including the module bearing. A module bearing includes a module outer wheel supported by and in contact with a side wall of a gear to guide rotational or linear motion of the gear, a bearing rotor rotatably disposed radially inward of the module outer wheel, and a part-assembly type module inner wheel disposed radially inward of the module outer wheel with the bearing rotor interposed therebetween and connected to the bearing rotor, in which a plurality of separate parts are manufactured and assembled into the part-assembly type module inner wheel to apply a preload to the bearing rotor.

A drawer slide including a base member, a roller support, ball bearings and roll pins. The base member a track base and first and second walls. The first and second walls and the track base define a first channel. The first wall has a first race and the second wall has a second race. The roller support is within the first channel. The roller support has first and second side walls and a center section disposed between the first and second side walls. The first and second side walls are disposed adjacent the first and second walls. The center section is disposed adjacent the track base. The first and second side walls have bearing apertures. The center section has roller openings. The ball bearings are disposed the first and second races. The roll pins are in the roller openings in rolling contact with the track base.

Provided is a guide roller for a vehicle sliding door. The guide roller rolls along a rail located on a vehicle body. The guide roller is pivotally supported in a rotatable manner by a support member coupled to the vehicle sliding door. The guide roller includes a ring-shaped inner race made of metal, a ring-shaped outer race, and a covering member mounted on an outer peripheral surface of the outer race.

A running carriage for a drawer pull-out guide, the running carriage includes a base body and a plurality of load-transmitting rolling bodies arranged in or on the base body. The load-transmitting rolling bodies are rotationally supported on the base body about a rotational axis orientated in a first direction. The running carriage further includes a first roller and a second roller rotationally supported on the base body about a rotational axis orientated in a second direction. The rotational axis oriented in the second direction extends transversely to the rotational axis orientated in the first direction, and the first roller has a larger diameter than the second roller.

A pair of elongated housings are positioned generally parallel to each other for connection of a wheel to a vehicle. An elongated member comprising a plurality of rollers is positioned within each of the housings. Spring biasing urges the elongated members downwardly, with the spring biasing absorbing shocks received at the wheel and conveyed to the elongated members, causing movement of the elongated members within the housing. The series of rollers on each of the elongated members traverse the housing to reduce friction between the housing and the elongated member as the elongated members traverse the housing. At least one vehicle wheel is mounted to the elongated members.

A drawer pull-out guide includes a first guide rail, a second guide rail displaceably supported relative to the first guide rail, and a running carriage which is displaceably supported between the first guide rail and the second guide rail. The running carriage includes at least three rolling bodies, each having a cylindrical form and being rotatable about a horizontally extending axis in a mounted position of the drawer pull-out guide. The at least three rolling bodies, in the mounted position of the drawer pull-out guide, are arranged in at least three running planes lying above one another.
