Hybrid ceramic ball bearing
The ceramic ball especially the silicon nitride ball has the characteristics of low density, high hardness, low coefficient of friction, wear-resistant, self-lubricating and good rigidity, Etc.,it is especially suitable for hybrid ceramic ball bearings’ rolling body (inner ring and outer ring are metal) of high-speed, high accuracy and long life. The inner ring and outer ring are generally used bearing steel (GCr15) or stainless steel (AISI440C),ceramic balls can choose to use ZrO2, Si3N4, or SiC materials.
