PROBLEM TO BE SOLVED: To provide a rolling bearing which is used under high temperature, high speed, and high load conditions and prevents peeling involving white tissue change caused by hydrogen even when water enters thereinto from an exterior part to achieve long life.SOLUTION: A rolling bearing of the invention holds rolling elements 14 between an inner ring 11 and an outer ring 12 through a holder 13 at substantially equal intervals so that the rolling elements 14 freely rotate. The holder 13 is made of conductive plastic. Protrusion parts 13A extending from the holder 13 to an outer peripheral surface of the inner ring 11 and an inner peripheral surface of the outer ring 12 are formed on an inner peripheral surface and an outer peripheral surface of the holder 13. Conductive grease is enclosed between the outer peripheral surface of the inner ring 11 and the inner peripheral surface of the outer ring 12.SELECTED DRAWING: Figure 1 |
