GUIDE MEMBER FOR ROLLING ELEMENT OF BEARING, METHOD OF MANUFACTURING IT, AND BEARING USING IT

摘要

PROBLEM TO BE SOLVED: To provide a bearing requiring little machining time and assuring good product yields with respect to materials and a good machining efficiency. SOLUTION: The bearing 1 includes an inner ring 4 consisting of an inner rolling element guide member 2 and an inner resin case 3 made of a resin molding incorporating the guide member, and an outer ring 7 consisting of an outer rolling element guide member 5 and an outer resin case 6 made of a resin molding incorporating the outer rolling element guide member, with a plurality of spherical rolling elements 8 disposed between the guide members 2 and 5. Each of the guide members 2 and 5 is a hollow cylindrical body having a rolling groove in its longitudinal center and having a flange 2a or 5a formed by bending one end of the cylindrical body; a configuration having a recessed groove for preventing slip of resin when the member is incorporated into the resin case 3 or 6 is integrally press molded in the flange 2a or 5a.
