ABSTRACT:
The linear motion rolling guide unit of this invention prevents galvanic corrosion by electrically insulating the mounting surfaces of the track rails and the casings as well as the surfaces in contact with other members. The track rails mounted on the base have rail raceway surfaces on both sides thereof. The casings have casing raceway surfaces facing the rail raceway surfaces, are mounted astride the track rails and slide on the track rail. A large number of rolling elements roll between the rail raceway surfaces and the casing raceway surfaces. Insulating members are interposed between the base and the mounting surfaces of the track rails. The mounting surfaces of the casings with respect to the end caps and the table are also provided with insulating members.
