All ceramic bearings are made of integral ceramic material, with ultimate high temperature resistance, corrosion resistance, and wear resistance. They have no magnetic insulation and low rotational resistance, high operating accuracy, and long service life. They are suitable for extremely harsh working conditions such as high temperature, strong corrosion, high speed, and non-magnetic
