<p>A roller-type linear sliding block includes a base block, two circulation-guiding blocks coupled to two ends of the base block and rollers received in the base block. The base block has a sliding groove corresponding to a linear sliding rail and a pair of load-bearing tracks formed at two sides of the sliding groove. The base block is formed with a cover member. The cover member is formed with non-load tracks beside the load-bearing tracks and retainers at two sides of each load-bearing track. Each circulation-guiding block includes an inner circulation member formed with an end of the cover member, a middle spacer and an outer circulation member connected to the inner circulation member in series to form a first circulation track and a second circulation track in the circulation-guiding block. Through the first and second circulation tracks, the rollers run in the load-bearing tracks and the non-load tracks.</p> |
