Ceramic bearings have high temperature, cold, wear, corrosion resistance, anti-magnetic insulation, oil-free self-lubrication, high speed and other characteristics. Can be used in extremely harsh environments and special working conditions, can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automotive, electronic equipment, metallurgy, electric power, textile, pumps, medical equipment, scientific research and national defense and other fields,
Ceramic bearings are mainly used in the classification of the use of
(1), high-speed bearings: cold resistance, small elasticity of the force, resistance to pressure, thermal conductivity and poor performance, Light weight, small friction coefficient and other advantages, can be used in 12000 rpm-75000 rpm high-speed spindle and other high-precision equipment;
(2), high-temperature bearings: the material itself has a high-temperature resistance of 1200 ℃, and self-lubricating and good, the use of the temperature in the 100 ℃-800 ℃ does not produce the expansion due to the temperature difference between the expansion. Can be used in the furnace, plastic, steel and other high-temperature equipment;
(3), corrosion-resistant bearings: the material itself has corrosion-resistant properties, can be used in strong acids, strong alkalis, inorganic, organic salts, seawater and other fields, such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment.
(4) Anti-magnetic bearings: non-magnetic, so do not absorb dust, can reduce the bearing surface spalling, thus reducing the operating noise. Available in demagnetization equipment. Precision instruments and other fields.
(5), electrical insulation bearings: because of high resistivity, can avoid arc damage bearings, can be used in a variety of requirements of the insulation of power equipment.
(6), vacuum bearings: because of the unique oil-free self-lubricating ceramic materials, in the ultra-high vacuum environment, can overcome the ordinary bearings can not realize the lubrication problem. Note: the above five categories of bearings, the same set of bearings can be applied to high temperature, high speed, acid and alkali, magnetic field, non-insulation, but because of the material properties are different (see the performance table of rare-earth ceramic materials), so please customers to choose the product, according to their own application occasions, to select the most suitable material ceramic bearings.
