PROBLEM TO BE SOLVED: To provide a rolling bearing adapted to requirement of a high speed rotation by preventing charging against surfaces of inner and outer ring members at the time of high speed rotation of a rolling body. SOLUTION: A plurality of rolling bodies 25 are interposed between both raceway tracks of the inner and outer ring members 22, 23 and the inner and outer ring members are made of a metal material. In the rolling body, at least a surface rolling/contacting with both raceway tracks has an insulation property. A grease 28 is filled against opposed annular spaces of the inner and outer ring members at a filling ratio of 20-35% of the total volume of the rolling body. COPYRIGHT: (C)2004,JPO
