A linear moving bearing, comprising: a retaining portion having at least one receiving chambers at lateral sides thereof; each receiving chamber being installed with at least one set of sliding track which is formed by two round rods; each of receiving chamber formed with two stop walls at an upper and lower ends of an opening of the receiving chamber; the stop walls serving to retain the round rods in the receiving chamber; each of the set of the sliding track resisting against a sliding rod so that the round rod being slidable along the sliding track. The stop walls are screwed or buckled to an upper and a lower end of a lateral wall aside the opening of the receiving chamber. The sliding rod has a sharp angle resists against a middle area between the two round rods of a set of the sliding track.

The present application concerns a telescopic rail comprising a first rail element, at least one further rail element and at least one rolling body cage for positioning a plurality of rolling bodies between two rail elements, wherein the rolling body cage has at least two receiving limbs having a respective plurality of through openings, wherein the receiving limbs together have a cross-section partially enclosing an internal space, and a plurality of rolling bodies received in the through openings in the receiving limbs, wherein the rolling body cage is arranged with the rolling bodies between the first rail element and the further rail element. According to the invention it is proposed that such a telescopic rail be modified to such an effect that the telescopic rail has a first group of rolling bodies and the rolling bodies of the first group are made of graphite, wherein the telescopic rail has a second group of rolling bodies and the rolling bodies of the second group are made of a material which is of greater hardness than the graphite of the rolling bodies of the first group, and wherein at least two rolling bodies of the second group are respectively received in the through openings of at least two receiving limbs.

A sliding linear bearing includes a guide shaft on which a slider is movably guided in a guide direction. Bushes are inserted between the guide shaft and the slider including a main bush that is fixedly attached to the slider and a preloading bush that is held so as to be rotatable relative to the slider about the guide direction while being preloaded with a torque. The main bush and the preloading bush are preloaded by the torque in opposite directions of rotation without play relative to the guide shaft. A contact region between each of the bushes and the guide shaft blocks rotation about the guide direction between the slider and the guide shaft in both directions of rotation.

A three-section synchronous slide rail, which has simple structure, longer service life, is easy to install and replace is provided, which includes: two sets of slide rail assemblies which comprise a fixed rail, a middle rail and a sliding rail, synchronization components comprising a flexible deflector unit and a roller, the flexible deflector unit is connected with the fixed rail and the sliding rail, the middle rail is connected with a rope base, a first end of the flexible deflector unit is wound around a first end of the rope base and fixed to the rope base, and a second end of the flexible deflector unit bypasses the roller and is reversely wound on a second end of the rope base and the second end of the flexible deflector unit is fixed to the rope base, a connecting rod is connected between the rope bases.

A slide rail assembly includes a first rail, a second rail, a slide assisting device, an elastic member and a working member. The second rail and the first rail are movable relative to each other. The elastic member is arranged on the second rail. During a process of the second rail being moved relative to the first rail along an opening direction, the working member is configured to contact the elastic member in an initial state in order to drive the slide assisting device to move along the opening direction to a predetermined position. When the slide assisting device is located at the predetermined position, the elastic member releases an elastic force through a predetermined space of the first rail, such that the elastic member is no longer in the initial state with the working member no longer contacting the elastic member.
