Abstract: There is disclosed a slide roller bearing including a race body, circulating rollers, spacers and upper and lower casing covers. The precision-machined track body defines on its circumference an endless circulating track which is provided with at least a pair of longitudinal channels and a center bank on the load-carrying side thereof and which is formed by a flat surface on the non-load-carrying side thereof. The spacers which retain the rollers in aligned state along the circulating track are each formed by a center supported body and a pair of spacing strips integrally formed at opposite lateral sides of the center body. The center body is provided with front and rear projections with upright sliding faces perpendicular to the axis of the rollers. The spacing strips are smaller than the rollers in length and have a thickness smaller than the diameter of the rollers. Each spacing strip has on its front and rear sides concave cylindrical faces of a radius of curvature substantially same as that of the circumferential surface of the rollers. The upper cover is provided with a pair of openings on opposite sides of a center retainer band and inwardly embossed guide portions substantially of U-shape in section in center portions contiguous to the non-load-carrying side of the circulating track, while the lower cover is provided with an inwardly embossed guide portion substantially of U-shape in section longitudinally along a center portion facing the non-load-carrying side of the circulating track.

Abstract: A rolling guiding device makes it possible to easily provide a movement block with an endless circulation path for the balls. In one surface of a movement block opposed to a rolling groove of a raceway rail, there is formed a track groove through which balls makes an endless circulation. The track groove is includes a load straight-line groove which allows, between the track groove and the rolling groove of the raceway rail, the balls to roll while bearing a load. It also includes a pair of ball deflection grooves respectively provided at both ends of the load straight-line groove and adapted to release the balls having rolled through the straight-line groove from the load and to change their rolling direction, and a non-load straight-line groove for transferring the ball in a non-load state from one deflection groove to the other ball deflection groove.

Abstract: Provided is a rolling guiding device which makes it possible to easily provide a movement block with an endless circulation path for the balls even in a case of a small-sized rolling guiding device using balls of a relatively small diameter and which can be produced easily and at low cost. In one surface of a movement block (2) opposed to a rolling groove (13) of a raceway rail (1), there is formed a track groove (21) through which balls (3) makes an endless circulation. The track groove (21) is composed of: a load straight-line groove (22) which allows, between the track groove (21) and the rolling groove (13) of the raceway rail (1), the balls (3) to roll while bearing a load; a pair of ball deflection grooves (24) and (24) respectively provided at both ends of the load straight-line groove (22) and adapted to release the balls (3) having rolled through the straight-line groove (22) from the load and to change their rolling direction, causing the balls (3) to leave the rolling groove (13) of the raceway rail (1); and a non-load straight-line groove (23) for transferring the ball (3) in a non-load state from one deflection groove (24) to the other ball deflection groove (24).

Abstract: Herein disclosed is a flanged linear ball bearing, in which a ball cage for arraying balls between a bearing housing and a bearing shaft is formed with a flange to be fixed on a mounting member such as a bed or a table. Thus, the bearing housing can be formed into a cylindrical shape having no flange so that it can be easily worked to drop the production cost and improve the production efficiency remarkably.
