Ceramic bearing


  Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the ring 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 GFRPA6625,PEEK,PI,Phonemice Textiles Tube, etc. Compares than the material of ZrO2,the SiN4 

ceramics bearings could endure heavier load and could be used in higher temperature environment. Also we could 

offer precision ceramic bearing which generally used in high-speed and high-rigidity spindle. the manufactured clearance could be P4 TO UP grade
