Silicon Nitride Ceramics for Roller Bearing Technology

The material's high wear temperature and chemical resistance properties make silicon nitride ceramics ideal for maintenance-intensive applications But that's not the only reason The fact that this ceramic material is an extremely low-friction and non-magnetic material with a very low specific weight excellent dry running properties and therefore superior emergency operating features is

Full Ceramic Bearings

Full ceramic bearings constructed entirely of ceramic material Inner/outer races and balls are made of either Silicon Nitride (Si3N4) Zirconium Oxide (ZrO2) or Silicon carbide (SiC) Full ceramic bearings are lighter smoother stiffer harder corrosion resistant and electrically resistant Full Ceramic bearings are used in extreme and in special environments like operating temperature

The difference between full ceramic bearings and hybrid

Ceramic ball bearings can be divided into two types: hybrid ceramic ball bearings and full ceramic ball bearings Among them the hybrid ceramic ball bearing means that only the rolling element parts of the bearing are made of ceramic materials and the full ceramic bearing means that the inner and outer rings and rolling elements of the

Current

Hybrid bearings in which the rolling elements are made from ceramic also have a current-insulating effect In this case the rolling elements prevent current passage Current-insulating bearings as a preventive measure In general it is difficult to eliminate the causes of electrical voltage in the rolling bearing Nevertheless bearing damage
