A three-section synchronous concealed slide rail includes a mobile rail, a middle rail, a fixed rail and a damping mechanism. An upper rack and an upper roller cage with an roller are installed between the mobile rail and the middle rail, a split-type lower roller cage with a roller is installed between the middle rail and the fixed rail, a surface of which is provided with a rack. A gear assembly is meshed between the upper rack and the lower roller cage and used for controlling synchronous or staggered operation of the mobile rail and middle rail according to the intensity of acting force, and the damping mechanism is installed on the fixed rail.

A Collision Bearing within a channel means, expressing the universal physical principle of collision. An assembly of two weight-bearing bearings, in two embodiments, for the purpose of moving objects. A slide plate must be attached to the support body of the bearings, whose width is in sliding contact with the inner channel walls, to align the motion of the bearings along the channel. This channel having a flange member, which retains the Collision Bearing within the channel. These two functions, rolling and sliding, simultaneously, demonstrates the universal physical principle of collision being claimed, and places the Collision Bearing in the category of a basic machine in the field of mechanics, as is for example, the nut and bolt. Impact pads are attached to the end walls of the bearing support body as a necessary component part in protecting this body.

A sliding device is capable of decreasing a moving distance of a middle rail while maintaining a maximum moving distance of a movable rail. The sliding device includes a fixed rail fixed to a body into which a storage body is inserted, the movable rail fixed to the storage body, the middle rail installed between the movable rail and the fixed rail and configured to move relatively with respect to the movable rail and the fixed rail, and a driving part configured to move the middle rail so as to move the movable rail by a distance twice a moving distance of the middle rail.

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.

The present invention relates to an apparatus for sliding friction free and lubricant free movement in vacuum, wherein the apparatus has a fixed position rail and a rail movable relative thereto by means of magnetic force. The invention further relates to a vacuum chamber, for example for a coating plant having an apparatus in accordance with the invention.

The present invention relates to the technical field of furniture and discloses a steel ball concealable three-section slide rail structure and a cabinet. The structure comprises a top rail, a middle rail, a bottom rail, and sliding members. The top rail and the middle rail are connected slidably, and the middle rail and the bottom rail are connected slidably. The top rail has a first insertion opening, and the bottom rail has a second insertion opening arranged opposite the first insertion opening. A first insertion portion of the middle rail is inserted into the first insertion opening to connect slidably with the top rail. A second insertion portion of the middle rail is inserted into the second insertion opening to connect slidably with the bottom rail. The steel ball concealable three-section slide structure of the present invention have stable sliding, less space occupation, and improved space utilization rate.

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 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.

An elongate rail (2) for use in a sliding support assembly (1), the sliding support assembly comprising a slide member (3) slidable in a longitudinal direction relative to the elongate rail and first (4a) and second locating assemblies, the elongate rail comprising a channel section defined by a first web, a first flange, and a second flange; a first wall (7a); and a second wall; wherein the first flange and the first wall (7a) define a first channel for retaining the first locating assembly (4a) and the second flange and the second wall define a second channel for retaining the second locating assembly.

A slide member having a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide member with low friction.
