Rolling Life Properties of Ceramic Bearings in Water

Abstract:

Rolling life properties of ceramic bearings in water were studied. In addition, we investigated the influence of ceramics, such as Si3N4, ZrO2 and SiC, on rolling life of bearings in water. All ceramic bearings possess from 15 to 70 times longer rolling life than all AISI440C steel bearings. All Si3N4 and ZrO2 ceramic bearings possess from 3.5 to 5 times longer rolling life than hybrid bearings. Rolling life of all SiC ceramic bearings is approximately the same as hybrid bearings. Rolling life of ceramic bearings in water is mainly due to propagation of cracks, pitting and flaking.
