ABSTRACT:
The linear motion rolling guide unit has: a track rail; a casing slidable relative to the track rail and having a pair of raceway surfaces; end caps mounted to the casing; V-shaped grooves formed between the raceway surfaces of the casing; a retainer having an engagement projecting portion engaged in the V-shaped groove; and a number of rollers circulating in contact with the facing raceway surfaces. The overall length of the retainer is set larger than that of the casing, and the ends of the retainer are engaged in the engagement grooves in the end caps to position the end caps with respect to the casing. Therefore, the positioning of the end caps on the casing can be made accurately without being affected by heat-treatment-induced deformation and machining errors.
