ABSTRACT:
A rolling guide unit in which the cross-section of a track rail is U-shaped wherein grinding processing of a track provided on the inside surface is facilitated. In addition, the thickness of the overall unit can be decreased by employing a self-traveling unit in which a motor is installed on a slider of a rolling guide unit. Grinding is facilitated by a split rail along one of the side walls of a track rail, and grinding can be performed with the split rail removed. In addition, since the entire outside surface of the side wall of the track rail can be used as a track for a rolling member, even if the track rail is flat, it is able to sufficiently transfer driving force, thereby allowing the thickness of the entire unit to be decreased.
