A linear module includes: a base, a slide stage, two support frames, two retaining units and a steel belt. With the pivoting freedom given by the guide portions of the retaining units, when the slide stage moves, the rolling elements can be abutted more closely against the contact surface of the steel belt via the pivoting of the guide portions, so as to reduce the occurrence of deformation and clearance produced by the steel belt, which not only improves the sealing performance of the steel belt and operation smoothness of the linear module, but also produces a dust proof effect, thus achieving the purposes of automatically adjusting contact angle, preventing deformation while extending the life of the steel belt.

A rolling guide device includes a track member, a moving member, and a plurality of rolling bodies. Rolling-body rolling surfaces that come into contact with an rolling-body outer circumferential surface of a rolling body are respectively formed in wall surfaces of a pair of wall portions included in the track member facing each other, a scraper including a pressing portion that presses the rolling-body rolling surfaces is turnably installed in the moving member, the scraper includes at least an attachment portion and a pressing portion, and is formed such that a frictional force of the pressing portion with respect to the rolling-body rolling surfaces is smaller than a frictional force of the attachment portion with respect to an attachment shaft formed in the moving member.

A linear roller bearing having a rolling body circulating shoe (15) including end-arranged attachment elements (16) as a lubricating device, wherein each attachment element contains a volume (9) for storing lubricant and transferring lubricant to a rail that guides the circulating shoe. According to the invention, the attachment element is formed from an inner housing shell (8b), which lies against the head piece (4) of the support body (1) of the circulating shoe, and an outer housing shell (8a), which faces away from the support body, which housing shells can be fastened to the head piece of the support body by a central screw (17).

An actuator includes a track member provided with a base extending along a longitudinal direction and a pair of walls erected from opposite ends of the base in a width direction, with rolling-element rolling grooves formed along the longitudinal direction; and a moving member assembled movably along the longitudinal direction between the walls, with respective load rolling-element rolling grooves corresponding to the rolling-element rolling grooves being formed in the moving members; and a screw shaft passed through a through-hole formed in the moving member, with a screw rolling-element rolling groove formed in the screw shaft, the screw rolling-element rolling groove being spiral in shape, wherein the moving member has the nut member attached to the through-hole, with the screw load rolling-element rolling groove corresponding to the screw rolling-element rolling groove formed in the nut, the nut member is assembled via a flange member which includes a lubricant supply device.

A linear motion assembly having a static coefficient of friction, S, as measured between an inner component and an outer component, and a dynamic coefficient of friction, .sub.D, as measured between the inner component and the outer component, wherein .sub.S/.sub.D is less than 2.0, such as less than 1.9, less than 1.8, less than 1.7, or even less than 1.6.

A slide rail assembly includes first and second rails, a ball bearing assembly, and a damping device. The first rail has front and rear ends and a middle portion therebetween. The second rail is displaceable with respect to the first rail. The ball bearing assembly is movably mounted between the front and rear ends of the first rail and includes a ball retainer with a plurality of balls and a stopping feature. The damping device is mounted on the middle portion of the first rail to provide a damping force corresponding to the stopping feature of the ball retainer. The ball retainer can be displaced by the second rail such that the stopping feature of the ball retainer contacts the damping device.

To provide a linear guide device having a higher dustproof performance and a dustproof function with a higher degree of freedom. A linear guide device includes a guide rail, a slider, and a rolling element, a seal member which seals a gap formed between a side surface portion of the guide rail and an inner side surface portion of the slider. The seal member includes a first seal member provided at the inner side surface portion of the slider, and a second seal member which is larger in width than the first seal member and is provided in a bottom surface portion of a slider body to be independently detachable from the bottom surface portion, as superimposed on the first seal member.

A non-magnetic ball housing can include an enclosed end and an open end. A plurality of non-magnetic ball bearings can be positioned within the enclosed end of the non-magnetic housing. A ball magnet can be adjacent to the plurality of non-magnetic ball bearings. A non-magnetic restraining plate can be coupled to the open end of the non-magnetic housing to secure the ball magnet within the non-magnetic ball housing while allowing the ball magnet to freely rotate within the non-magnetic ball housing.
