ABSTRACT:
It is an object of the invention to provide a needle bearing which can prevent occurrence of flake and seizure in the bearing parts even under such severe lubricating condition as provided by a compressor for a car air conditioner or a planetary unit for an automatic transmission. The needle bearing is structured by barrel grinding the raceway surface of a ring and the surface of a rolling body without using a ceramic-related abrasive such as alumina or silicon carbide.
