SOLID LUBRICATION ROLLING BEARING AND RESIN CAGE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a resin cage which reduces a guide clearance for securing the high speed stability of the resin cage while securing a suitable guide clearance.SOLUTION: In a resin cage used in a solid lubrication rolling bearing, a circumferential direction area of an end face 14 of a resin cage 8 corresponding to a pillar 12 between pockets 10 is provided with a thinner portion 16, which allows an outer diameter face 18 to elastically deform into wave shape in high speed rotation.
