ROLLING BEARING

摘要

A seal ring including filters is mounted to a rolling bearing. The bearing includes rolling elements disposed between an outer race and an inner race. The seal ring is made of a resin or a metal and covers an end opening of the bearing space defined between the outer race and the inner race. The filters are detachably fitted in oil flow holes formed in the seal ring. The filters catch foreign matter contained in lubricating oil. The seal ring is engaged by one of the outer race and the inner race. An annular member made of a material softer than the seal ring is fixed to the seal ring. The annular member serves as a lip facing the other of the inner and outer races with a gap left therebetween, or in abutment with the other of the inner and outer races.
