Abstract
A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.
