Ceramic bearing is a new material application of high-tech product with good features of high temperature resistance cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation, oil-free self- lubrication, high speed and so on. It can be used in extremely harsh environment and special conditions, and widely used in aviation, aerospace navigation, petroleum, chemical industry, automotive, electronic equipment, metallurgy, electric power, textile, pump,medical equipment,scientific research and national defense and other fields. The rings and roller of ceramic bearing are made of ceramic materials, including zirconia (Zro2), silicon nitride (Si3N4) and silicon carbide (Sic). And the cage is made of PTFE/ PEEK/ UPE/ PVDF/ PA66/SUS304/ SUS316 and ceramic materials.
Main benefits:
High-speed bearing: Ceramic is resistant to cold, low force elasticity, high pressure resistance, poor thermal conductivity. light weight, small friction coefficient etc. It can be used in high-speed spindle with 12,000 RPM-75,000 RPM and other high-precision equipment.
High temperature bearing: the material itself has a high temperature resistance of 1200°c and self-lubricating, it won’t cause expansion when the using temperature is differ from 100°C to 400°c. Therefore, ceramic bearing can be used in furnace, plastic steel and other high-temperature service.
Corrosion resistant bearing: As the material itself has the characteristics of corrosion resistance, it can be used in strong acid alkali, inorganic, organic salt, seawater and other fields, such as electroplating equipment, electronic equipment,chemical machinery, shipbuilding, medical equipment and so on.
Anti-magnetic bearing: Because there is no magnetic,it does not inhale dust, which can reduce the spalling of the bearing surface, thus reducing the operating noise. Now ceramic bearing can be found in demagnetization equipment, precision instruments and other fields.
Electrically insulated bearing: As the high resistivity, it prevents the bearing from being damaged by electric arcs. And it can be applied in electrical equipment requiring insulation.
Vacuum bearing: Because of the unique oil less self-lubricating property, it overcomes the problem that the ordinary bearings cannot be lubricated in the ultra-high vacuum environment.
Note: We can provide the above six types of bearings. The same set of bearings can be applied to high temperature, acid and alkali magnetic field he insulation. Because of the different material performance, please inform us your application occasions when you choose our products, we will choose the most suitable ceramic bearing for you.
