A linear slide includes: a rail; a slide block, which is mounted on the rail and is movable relative to the rail; a plurality of rolling elements, which are arranged between the rail and the slide block; two end caps, which are respectively mounted to two ends of the slide block, the end caps each comprising a mounting trough formed therein to correspond to and face the rail, the mounting trough having a wall; and two dust protection plates, each of which is arranged in each of the mounting troughs, each of the dust protection plates comprising a main body and two elastic sections projecting from two opposite sides of the main body such that one of the elastic sections is in contact engagement with the wall and the other one of the elastic sections is engageable with a surface of the rail.

A movement guide device comprises: a support body formed with two roller rolling grooves in each of two side surfaces thereof; a moving body assembled onto the support body to freely move along the support body, and having a load roller rolling groove provided opposite to the roller rolling groove to form a load path together with the roller rolling groove; rollers arranged such that lines forming a contact angle with respect to the roller rolling groove intersect at a position outside the support body; and a roller retaining member arranged between two row of rollers, the moving body comprises a main moving body and cover bodies mounted at two ends of the main moving body; in the movement guide device, the roller retaining member comprises a roller retaining portion, formed in a plate shape extending in a length direction of the support body, and orthogonal to the length direction.

An object is to provide a motion guide apparatus that can facilitate an assembly operation. An end member (4a, 4b) including an inner peripheral side of a direction changing path (2c) is placed on an end surface in a movement direction of a moving member body (3). At least one of a pair of the end members (4a and 4b) includes an opening (21) linking to the inner peripheral side of the direction changing path (2c) to load rolling elements (42) into a circulation path. Opposing surfaces (18) of the pair of the end members (4a and 4b) to the moving member body (3) are formed in flat surfaces. The pair of the end members (4a and 4b) molded integrally with a holding portion (5) is incorporated into the moving member body (3) in a direction orthogonal to the movement direction of the moving member body (3). A lid member (7a, 7b) closes the opening (21) in the end member (4a, 4b).

A guide carriage of a linear guide, which guide carriage has a back (1) and legs (2) bent away from the back (1) and disposed along a longitudinal axis of the guide carriage for engaging over a guide rail (7), the two legs (2) are each provided with a longitudinal seal (5) having rod-shaped bodies (12) each of which has a sealing lip (8) on sides facing one another. The rod-shaped body (12) is supported on an abutment (9a) of the leg (2) provided along the longitudinal axis, wherein the rod-shaped body (12) is retained on the guide carriage together with the two axial rod ends (13, 15, 18) of the rod-shaped body (12) and is spring-loaded against the abutment (9a) by means of the inherent spring force of the rod-shaped body (12).

A sensor device for a rolling path insert of a track guide can be loaded by rolling bodies and is pressure-sensitive. The sensor device includes at least one tuple, extending in a rolling direction, of a number of sensors, which can each be signal-connected or are signal-connected to an evaluation device, by means of which a relevant difference signal can be determined from sensor signals of sensor pairs of the at least one tuple. The sensor device can be included in a rolling path insert, a guide carriage and a guide rail for a track guide, and a track guide.

A linear guideway and an end module thereof are provided. The end module includes a cap and a circulation sheet. The cap includes a transverse segment and two lateral segments that are respectively connected to two ends of the transverse segment. The circulation sheet is engaged in the transverse segment and the two lateral segments so as to jointly define an oil injection channel. The circulation sheet and the two lateral segments jointly define a plurality of turning channels. When a lubricating oil is injected into the oil injection channel of the end module, the circulation sheet absorbs a part of the lubricating oil and expands so as to be tightly fitted to the transverse segment and the two lateral segments of the cap.
