ULTRA-THIN TYPE ROLLING BEARING, AND CAGE FOR ULTRA-THIN TYPE ROLLING BEARING

摘要

PROBLEM TO BE SOLVED: To positively prevent separation of a cage.;SOLUTION: The cage 35 for the ultra-thin type rolling bearing is annularly formed by joining a plurality of arced segments 36 in a circumferential direction, pockets 40a and 40b housing rolling elements 34 are formed at a predetermined interval in the circumferential direction, and a non-connected part 37 of the segments 36 is provided in one part in the circumferential direction. A lid member 43 used as a separation preventing means for increasing separation force of the rolling element 34 more than other pockets 40a and 40b is attached to an axial opening side of the pocket 40a positioned in an end 42 of the segment 36 adjacent to the non-connected part 37 and facing the circumferential direction.;COPYRIGHT: (C)2007,JPO&INPIT
