Hybrid bearings in oil-free air conditioning and refrigeration compressors

摘要

A challenge with hybrid bearings is the development of cost-effective manufacturing technology for high-quality ceramic rolfing elements. With technological advances, the cost of ceramic bails has come down significantly over the past 10 years, and it is anticipated that ceramic rollers will follow the same development. The design of the surface texture and curvature of the steel raceways, the quality of the ceramic components and the design of the bearing cage are other important considerations in the development of a hybrid bearing to be used in pure refrigerant lubrication.
