    ZrO2 Ceramic Bearings , Full Ceramic Bearings


    ZrO2 Full ceramic bearing have excellence performance as special electrical and magnetism 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 were made by full ceramic material:ZrO2, as a standard construction, the cage was made by PTFE, generally we also could make the cage with GFRPA66-25, PEEK, PI, AISI SUS304, SUS316, Cu, etc.
