Kove Bearing widely used in assembling of semiconductor, plating machinery , PCB machinery , Petrol, Chemical, Electrical, Food, Medical, Marine, Aerial industry, It can be used in extreme badly environment and special situation. About the Corrosion resistance, nonmagnetic insulated, high temperatures of full ceramic bearing:1. (Outer, inner ring and ball with ceramic ZrO2 material, the cage with PTFE) the temperature will attainability within 260 centi-grade 2. (Outer, inner ring and ball with ceramic ZrO2 material, no cage) the temperature will attainability 260~300 centi-grade3. (Outer, inner ring and ball with ceramic Si3N4 material, the cage with PTFE) the temperature will attainability within 260 centi-grade4. (Outer, inner ring and ball with ceramic Si3N4 material, no cage) the temperature will attainability 260~1100 centi-grade About the Ceramic bearing's cage material have PEEK, UPE, PA66, and PTFE and so on. And we can accord our customer request to make
