Full Complement Ball Bearing of Si3n4

All-Ceramic Bearings Made With Si3N4Full ceramic bearings made with SiN4 have some better performance than ZrO2, the rings and balls made by full ceramic material: Si3N4, as a standard constructure, the cage made by PTFE, generally we also could make the cage with GFRPA66-25. PEEK. PI, Phonemic Textiles Tube, etc. Compares the material of ZrO2, The Si3n4 ceramic bearings could endure heavier load and could be used in higher temperature environment. Also we could offer precision ceramic bearings which generally used in high-speed and high-rigidity spindle. The manufactured clearance could be P4 to UP grade. More Performance of thr ceramic bearings: High temperature resistant, high speed, low temperature resistant, flammable, explosive, corrosive, vacuum, electrical insulation, non-magnetic, dry friction. (1), High-speed bearing: With the advantages of cold resistance, small mechanical elasticity, resistance to high pressure, poor thermal performance, light weight, small friction coefficient, the high-speed ceramic bearings can be used in the the spindle of 12000 r/min to 75000 r/min and other high precision equipment; (2), High temperature resistant bearing: The material itself has the resistance to high temperature of 1200 degrees centigrade, and good self-lubrication, bearing used in the temperature between 100 degree scentigrade to 800 degrees centigrade will not cause expansion of the material. They can be used in the furnaces, high temperature equipment such as plastic, steel; (3), Corrosion resistant bearing: The material itself has the property of corrosion resistance, which can be used in strong acid, strong alkali, inorganic, organic salt, water, and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc. (4), Anti magnetic bearing: For non-magnetic do not absorb dust, can reduce the bearing early spalling, large noise, etc. Available in the demagnetization device. Precision instruments and other fields. (5), Electric insulation bearing: Due to high electric resistance, ceramic bearings can avoid damage of bearing arc, it is available in various equipment which requires of insulation power. (6), Vacuum bearing: As the unique properties of oilless & self-lubrication that ceramic has, ceramic bearings can overcome the lubrication problem in the ultra high vacuum environment, Note: The above five categories of bearings, each can be applied in high temperature, high speed, acid and alkali, magnetic field, the insulation. But due to the different material properties rare earth ceramic material performance, customers should choose the most suitable ceramic bearing material according to their own application occasions.
