Abstract
A linear motion guide unit in which the smaller pitch between the center-lines of adjacent rollers installed in a cage results in the greater number of the rollers lying in a preselected length of the cage to increase load-carrying capacity. The cage plate has openings for retaining the rollers arranged in the lengthwise direction of the cage plate. Each of the openings has a contour whose major axis lies in a widthwise direction of the cage plate. Bearing lips retain axially opposite end surfaces of the rollers, the bearing lips extending inside from an edge around the opening at locations corresponding with diametrically opposite ends of the major axis. The bearing lips end into wedged bearing edges deformable elastically. The bearing edges have bearing slants that conform to the end surfaces of the roller to bear the roller thereon. The bearing slants are in diametrically symmetric relation to each other.
