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.
