ABSTRACT:
A linear motion guide unit has a track rail of a pair of side walls on which raceway grooves are formed. In the depths or bottom of the raceway grooves there are cut deeply relief flutes, one to each raceway groove, where retainer bands to keep rolling elements against coming apart are allowed to step aside therein. The raceway groove is made in so specific form as to make it possible to produce the raceway groove and do the relief flute at the same time. The retainer band is installed in the slider, with stepping aside in the relief flute for linear movement relative to the track rail as the slider travels along the track rail. The relief flute is cut in a fashion at least one lengthwise flank thereof on the side nearer the upward opening between the side walls of the track rail is made slantwise to provide a tapered flank because of which the relief flute can be produced together with the associated raceway groove at a single process.
