<p>A linear motion guide unit is disclosed in which a separator is made to fit over or embrace any adjacent rolling element, thereby realizing quiet operation and wear-resistance, with even under high-speed, high-cycle sliding motion. The separator has a round outside peripheral surface, and forward and aft end faces that are made concave to fit over the associated rolling elements. An end cap is made up of a spacer part having a lug to provide a radially inside curved surface of a turnaround, and a major part to provide a radially outside curved surface of the turnaround when mounted on a carriage through the spacer part. Cut in the radially inside curved surface on the lug is a gutter for relief, which extends circumferentially ilk along the center of the radially inside curved surface on the lug, thereby allowing the separator to travel through the turnaround without any interference with the radially inside curved surface of the turnaround.</p> |
