Full ceramic bearing made with Si3N4 have some better performance than ZrO2, the rings and balls made by full ceramic material:Si3N4, as a atandard constructure, the cage made by PTFE, generally we also could make the cage with GFRPA66-25, PEEK, PI, Phonemic Textiles Tube, etc. Comparing with the material of ZrO2, the Si3N4 ceramics bearings could endure heavier load and could be used in higher temperature environment. Also we could offer precison ceramic bearing with generally used in high-speed and high-rigidity spindle, and the manufactured clearance could be P4 to up grade.
