Claims

[Scope of utility model registration request]

In a rolling bearing that includes rolling elements arranged between an outer ring and an inner ring, and a cage that holds and guides the rolling elements, the outer ring, the inner ring raceway surfaces, and the rolling elements have a soft metal coating on their surfaces. The retainer is made of a metal material containing a layered solid lubricant, and the layered solid lubricant is attached to at least a portion of the surface of the rolling element or the surface of a mating member in contact with the rolling element. A rolling bearing characterized by:
