PURPOSE:To prevent emission of hydrocarbon gas at least from a lubricating film laid on a sliding contact surface between a cage and a rotary element under the environment of high temperature. CONSTITUTION:In a rolling bearing using a cage 4, the inner surface of each pocket of the retainer is coated with a lubricating film 5 comprising fluororesin and resin binder imide-combined or amide-imide combined with the resin. The burning temperature of the lubricating film 5 is set in such a manner that during burning, every hydrocarbon gas is emitted out from the lubricating film 5. |
