silicon carbide bearing offers the best heat and corrosion resistance of all the ceramic materials.
Silicon Carbide is best used under low loads and in highly corrosive environments.
and with full complement types, silicon carbide bearing can be used up to 1200°C working tempearture.

3).Corrosion-resistant bearings
4).Electric-insulated bearings
5).Vacuum bearings:self-lubricating without
Ceramic SIC Bearing Application :
Full ceramic sic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc.
Note:
Full ceramic bearing is not suitable for heavy loading, impact loading and variable loading application.
Ceramic Material Comparison:
Material: ZrO2, Si3N4, SiC and Al2O3, etc.
1.ZrO2 Full Ceramic Bearing
Zirconium oxide ceramic bearing(ZrO2):the rings and balls are all zirconium oxide ceramics with cages made by PTFE,nylon strengthened by glass fibles.
2. Si3N4 Full Ceramic Bearing
Full ceramic bearing made with Si3N4 have some better performance than Zr02, the rings and balls made by full ceramic material: Si3N4, as a standard constructure, the cage made by PTFE, generally we also made the cage with GFRPA66-25, PEEK, PI, Phonemic Textiles Tube, etc.
Compared with the material of ZrO2, the Si3N4 ceramic bearings could endure heavier load and could be used in higher temperature environment.
