Abstract
A linear motion guide unit is disclosed, in which a track rail and a slider have respectively reference surfaces that serve to locate accurately them with respect to a bed and a table, thereby keeping the track rail and slider against dislocation as well as changes in posture. The track rail is mounted to the bed, with a reference side surface for mounting and a reference bottom surface for mounting of the track rail being brought into abutment against a mounting side surface and a mounting top surface of the bed, respectively. The slider is mounted to the table, with a reference side surface for mounting and a reference top surface for mounting of the slider being brought into abutment against a mounting side surface and a mounting lower surface of the table, respectively.
Claims12
A linear motion guide unit, comprising a track rail to be mounted to a bed and having a pair of lengthwise side walls connected to each other, and a slider to be mounted to a table movable relatively to the bed so as to move lengthwise along the track rail in a guiding way defined between the side walls of the track rail, wherein the slider has a slider head not more than the guiding way in width and protruding above top faces of the side walls, the track rail is provided with a first reference surface for mounting, against which a mounting surface formed on the bed comes in abutment, and the slider head is provided with a second reference surface for mounting, against which a mounting surface formed on the table comes in abutment.
