WIPO Patent Application WO/2017/104787

Kind Code:

A1

Abstract:

Provided is a deep-groove ball bearing that is used under lean lubrication conditions or non-lubrication conditions and that makes it possible to achieve a long lifespan without producing cage breakage by the advance or lag of a ball. A plurality of balls interposed between an inner and an outer race in this deep-groove ball bearing are held by a riveted corrugated iron-plate cage. The deep-groove ball bearing is used under lean lubrication conditions or non-lubrication conditions. A fluororesin coating, preferably fired polytetrafluoroethylene or the like, is formed in a thickness of 15 μm or greater at least on an inner surface portion of the cage or the raceway surface of the inner/outer race that moves with friction relative to the balls.
