Corrosion Resistance Ceramic Plain Bearings ZrO2 Material Ceramic Cage
Ceramic Cage , All-ceramic Bearings
Ceramic cage has excellence performance as wear and corrosion resistance, high strength, lubrication and maintenance free when working. Adopting the ceramic cage, Ceramic bearing can be used in the most inclemency environments as corrosive, low temperature, high vacuum. The material of almost ceramic cage is ZrO2.
