Angular contact ball bearings zirconia ceramic 

 

Gongtao company specilize in making various ceramic bearing made of ZrO2,Si3N4 ect.Full ceramic bearing have excellence performance as special electrical and magfuteism resistance, wear and corrosion resistance,lubrication and maintenance free when working,especially high and low- temperature application .etc. could be used in awful environment and specially condition. The rings and balls made by full ceramic material:ZrO2, as a standard constructure,the cage made by PTFE, generally we also could make the cage
