1.High-speed: Ceramic bearings have the advantages of cold resistance, low elasticity, high pressure resistance, poor thermal conductivity, light weight, and low friction coefficient. They can be used in high-speed spindles and other high-precision equipment from 12,000 to 75,000 rpm.
2.High temperature resistance: The ceramic bearing material itself has a high temperature resistance of 1200 degree, and a good self-lubrication. No expansion will be caused due to temperature differences between 100 degree and 800 degree. It could be used in furnaces, plastics, steel and other high temperature equipment.
3.Corrosion resistance: The ceramic bearing material itself has the characteristics of corrosion resistance, can be applied in the fields of strong acid, alkali, inorganic, organic salt, seawater, etc., such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4.Antimagnetic: Ceramic bearings do not attract dust due to non-magnetic, which can reduce the bearing's premature peeling and high noise. It can be used in demagnetization equipment. Precision instruments and other fields.
5. Electrical insulation: Ceramic bearings have high electrical resistance, can avoid arc damage to bearings. They can be used in various electrical equipment that requires insulation.
6. Vacuum: Due to the unique oil-free self-lubricating characteristics of ceramic materials, silicon nitride full ceramic bearings can overcome the problem that ordinary bearings cannot achieve lubrication in an ultra-high vacuum environment.
