What are the characteristics and application advantages of hybrid ceramic bearings?

Due to the high elastic modulus of ceramics, the contact surface of hybrid ceramic bearings is smaller, which is beneficial to reducing rolling and sliding friction. In addition, the density of ceramics is lower than that of steel, so the centrifugal force is smaller, thus reducing friction at high speeds. In high-speed applications, axial preload is typically added to the bearing arrangement. In this case, deep groove ball bearings work on the principle of angular contact ball bearings; therefore, at high speeds, friction can be reduced to a more ideal level. Less friction means lower operating temperatures and longer lubricant life. Therefore, hybrid ceramic bearings are ideally suited for high-speed applications. Even in the case of insufficient lubrication, there will be no wear problem between silicon nitride and steel, so hybrid ceramic bearings can still run for a long time in the case of poor lubrication. For hybrid ceramic bearings, hybrid ceramic bearings may still perform well when some media that only form a very thin lubricating film, such as refrigerants, are used as lubricants. The hardness and elastic modulus of silicon nitride are higher than ordinary bearing steel, so the bearing has higher stiffness and can have a longer working life in polluted environments.
