ABSTRACT:
Each of the inner and outer rings of a non-retainer type rolling bearing has a wear-resistant solid film of a fluorine-containing synthetic resin formed on its track surface. The solid film carries a very small amount of grease having a low vapor pressure, e.g. fluorine-containing grease, as an effective lubricant for the inner and outer rings, and the rolling elements held therebetween, while the solid film is also restrained from producing dust. The amount of the grease does not exceed 5% of the volume of the open space in the bearing.
