Feature 1Hardly corroded, the ceramic rolling bearing is suitable for working under severe conditions filled with corrosive medium. 2Due to electrical resistance, electrical insulation, can avoid arc damage bearings, can be used in a variety of insulation of power equipment. 3Since the effect of thermal expansion and contraction of ceramics is smaller than that of steel, the bearing can be allowed to work in an environment where the temperature difference changes more severely. 4Since the elastic modulus of ceramics is higher than that of steel, it is not easy to deform when subjected to stress. So it is advantageous to increase the working speed and achieve higher accuracy. 5Because of no magnetic, it can reduce premature bearing flaking, big noise. Available in the demagnetization device, precision instruments and other fields.Specification Full ceramic bearing with diamagnetic electrically insulating, wear resistance and corrosion resistance, not self lubricating, high temperature resistance, cold and other characteristics, can be used in extremely harsh environment and special conditions.
