ABSTRACT:
A linear roller bearing unit is disclosed in which a bearing body of channel-like cross section is mounted through rollers on a guide rail for linear motion therealong. The bearing body is formed at the central portion of the inner peripheral surface thereof with a longitudinally extending central groove, and at the opposite side portions of the inner peripheral surface thereof with a pair of longitudinally extending side grooves. The central groove is provided at its bottom surface with a pair of longitudinally extending loaded roller rolling surfaces in face-to-face relation with the corresponding loaded roller rolling surfaces on the guide rail. Each of the side grooves is provided at its bottom surface with a longitudinally extending loaded roller rolling surface in face-to-face relation with the corresponding loaded roller rolling surface on the guide rail. The bearing body further has four non-loaded roller rolling passages formed therethrough. Four rows of rollers are interposed between the opposed loaded roller rolling surfaces on the bearing body and the guide rail. Between the bearing body and the guide rail there are disposed retainers for guiding and holding, in cooperation with the side surfaces of the central and side grooves, the rollers rolling between the opposed roller rolling surfaces.
