A slide rail device which includes a lower rail, an upper rail which is freely slidably engaged with the lower rail, and balls which are installed between the lower and upper rails. The lower rail includes a lower-rail bottom wall, a pair of lower-rail side walls, a pair of lower-rail upper wails, a pair of lower-rail lower-ball contact R-portions, and a pair of lower-rail upper-ball contact R-portions. The upper rail includes an upper-rail top wall, a pair of upper-rail side walls, and a pair of upper-rail ball-bearing walls. Each upper-rail ball-bearing wall includes an upper-rail lower-ball contact portion and an upper-rail upper-ball contact portion. A radius of curvature of the lower-rail lower-ball contact R-portion of the lower rail is greater than that of the lower ball, and a radius of curvature of the lower-rail upper-ball contact R-portion of the lower rail is greater than that of the upper ball.

The slide assembly includes a first rail, a second rail, a bearing assembly and an engaging member. The first rail includes an opening located adjacent to an end thereof and a stop face is defined on a wall of the opening. The bearing assembly is located between the first and second rails. The bearing assembly has a bearing retainer which has a first contact portion. The engaging member is connected to the second rail and has a second contact portion and an engaging portion. The second contact portion is located corresponding to the first contact portion. When the second rail is pulled relative to the first rail, the bearing retainer is moved by engagement between the first and second contact portions. When the bearing assembly moves to a desired position, the engaging portion is inserted into the opening and contacts the stop face so that the second rail is engaged with the first rail.

A method of making a bearing assembly and a bearing assembly is provided. The method includes the steps of extruding a support rail, providing a mounting surface on the support rail, mounting a bearing rail on the mounting surface and machining a bearing surface on the bearing rail. The bearing assembly includes an extruded support rail and a bearing rail. The bearing rail is of a harder material than the material of the support rail to which the bearing rail is mounted. The bearing rail further provides a machine polished linear contact.

Slide assemblies that include at least an inner slide segment and an outer slide segment. Many of the slide assemblies also include an intermediate slide segment interposed between the inner slide segment and the outer slide segment. One or more of the segments can be constructed of an aluminum material, which is extruded into a final cross-sectional shape. A slide assembly can include a combination drop-and-lock and disconnectable inner slide segment. A slide assembly can include a lock closed arrangement having a lock arm that passes through an opening of a mounting rail of the server rack. A slide assembly can also include a self-resetting hands-free disconnect arrangement.

The actuating device is capable of automatically eliminating a clearance between a contact body and a rail. The actuating device comprises: a moving body guided by the rail; the contact body contacting the rail; and a pressure unit biasing the contact body toward the rail or in a pressing direction. The pressure unit comprises: a rod having one end, which contacts the moving body, and the other end, the rod being capable of moving in the pressing direction; a first biasing member biasing the rod; a casing covering an outer face of the rod, the casing having an inner face, whose distance from the outer face of the rod is gradually reduced toward the other end of the rod; and a spherical body contacting the inner face of the casing and the outer face of the rod.

A workcenter (10) comprises its supports (14a,b,c) which each carry a carriage (24a,b,c) movable along the supports by motors (30a,b,c) under central computer control (41).Each support is an aluminum extruded U-shaped section having four tracks (28) comprising steel strips (27) in slots (29).The carriage is likewise extruded having undercut slots (83) receiving the heads (92) of axles (90) which have eccentric stubs (96) on which bearing wheels (26) are journalled. Four wheels are so-mounted at each end of the carriage.

Two shafts (20) of a linear motion guide unit (10) are clamped together on a support (12) with positive line locking by bolts (24) engaging tapped pocket holes (22) inclined an acute angle (.alpha. ) relative to each other, one screw-hole (42) in the support (12) being inclined relative to a neighboring hole or to a mirror-symmetrical pair of counter-holes (44). Rail bodies (14) of aluminium integral with flat bars (30) include a fillet (26) with an adjacent crest (16) and a recessed step (28). Abutting shaft ends (47) may be clamped, by bolting at a counter-hole pair (44), to a through-shaft fixed at a central hole (42) on a single support (12 or 31). A continuous rail body having spaced groups of screw holes (40, 41) may be part of a box-like hollow section (64). In a three-cavity profile (70), two outer hollow sections (64) join a center cavity (71). A motor-driven carriage (49) includes strings of balls (54) or rollers (55) for engaging the outer surfaces (21) of the shafts (20) and supports a slide member (60) for zipping operation of self-sealing lips (61) situated at an open hollow section (64) side.

The invention relates to an X-ray examination apparatus comprising a vertical pillar at which a truck carrying an X-ray system is longitudinally displaceable. The pillar is a closed box profile and includes a U-shaped depression proceeding in longitudinal direction at each of two parallel long sides lying opposite one another, whereby the depressions serve as rails for the truck longitudinally displaceable on the pillar.
