ABSTRACT:
A linear slide roller bearing unit for use in, for example, a machining center has a track shaft extending in the longitudinal direction of the linear slide roller bearing unit and having loaded roller rolling surfaces respectively formed on both side surface portions of each of the right and left ridges thereof projecting in the direction of an imaginary oblique line intersecting the horizontal axis at an angle of about 45.degree.. The linear slide roller bearing unit further has a movable table constituted by a long block member disposed so as to straddle the track shaft, the movable table having longitudinal recesses respectively formed in the opposing inner surfaces of skirt portions thereof. A pair of right and left bearing bodies are each constituted by a long block member which is screwed to the corresponding recess in the movable table, each bearing body having a guide ridge projecting from the center of each inner side surface portion of the block member, each guide ridge having one side surface thereof defined as a loaded roller rolling surface confronting the corresponding loaded roller rolling surface of the track shaft and the other side surface defined as a non-loaded roller rolling surface.
