Abstract
The utility model discloses a carbon graphite retainer rolling bearing for performing protective and antifriction treatment. The rolling bearing comprises a bearing outer ring, a bearing inner ring, a rolling body embedded between an outer ring raceway and an inner ring raceway, and a carbon graphite retainer for uniformly distributing the rolling body along a circumferential direction at intervals, wherein protective antifriction layers respectively cover the steel bearing inner and outer rings and the rolling body. The corrosion resistance of the steel parts in an oil-free state is improved, and the lubricating capacity of the steel parts is improved, so that before a carbon graphite transfer lubricating film is fully formed in the bearing at an initial operating stage of the bearing, the working surfaces of the steel parts are protected by the protective antifriction layers and cannot be corroded due to poor lubrication. Therefore, the operating reliability of the carbon graphite retainer rolling bearing is greatly improved, the service life of the carbon graphite retainer rolling bearing is greatly prolonged, and the carbon graphite retainer rolling bearing has high engineering application value.
