Abstract

PURPOSE:To simplify the adjustment of a preliminary pressure by forming a circulation means for balls pinched between respective loaded ball grooves and circulating infinitely the balls. CONSTITUTION:Each curvature of each of loaded ball grooves 11, 11' of track member 10 and loaded ball grooves 21', 21'' of a bearing body 21 is adjusted so as to pinch loaded balls 30. A return cap has turning grooves to turn the running direction of the balls by 180 deg.. Accordingly, no-loaded balls which are turned in their running directions by 180 deg. are guided to no-loaded ball grooves 21''' passing through the bearing body 21. Thus, the balls are circulated infinitely and the adjustment of a preliminary pressure is simplified.
