Zirconia full ceramic bearings have the characteristics of non-magnetic and electrical insulation, wear resistance, corrosion resistance, Grease-free self-lubrication, high temperature resistance, low temperature resistance, etc., and can be used for extreme aggression and special working conditions. With the advantage of low centrifugal force, it can enlarge the lifetime of the bearing. And the wear resistance performance of Si3N4 cermaic balls is better than ZrO2 ceramic balls.
