Abstract:
A rolling bearing which has excellent performance at high-temperatures and has high-speed durability and quietness, is capable of effectively preventing hydrogen brittleness-caused peeling from occurring on a rolling surface thereof, and has a low environmental load. The rolling bearing (1) is constructed of an inner ring (2) having a rolling surface on its peripheral surface, an outer ring (3) having a rolling surface on its inner peripheral surface, a plurality of rolling elements (4) disposed between both rolling surfaces, and a cage (5) retaining the rolling elements (4). The inner ring (2), the outer ring (3), the rolling elements (4) or the cage (5) are metal-made bearing members. Film-coating treatment is conducted on a sliding surface or a rolling surface of at least one of these metallic bearing members with plant-derived polyvalent alcohol compounds such as curcumin, quercetin, chlorogenic acid or the like.
