High Temperature Ceramic Bearings
Features
Ceramic series bearings have the characteristics of anti-magnetic, electrical insulation, wear and corrosion resistance, oil-free self-lubrication, high temperature resistance, cold resistance, etc., and can be used in extremely harsh environments and special working conditions.
The ceramic thrust bearing rings and rolling elements are made of zirconia (ZrO2), silicon nitride (SI3N4) ceramic material, and the cage is made of polytetrafluoroethylene (PTFE). Glass fiber reinforced nylon 66. (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), brass (CU), etc. can also be used.
1. High speed: Ceramic thrust bearings have the advantages of cold resistance, low elasticity, high pressure resistance, poor thermal conductivity, light weight and low friction coefficient. It can be applied to high-speed spindles such as 1200 rpm/7500 rpm. High precision equipment.
2. High temperature resistance: The ceramic thrust bearing material itself has a high temperature resistance of 1200 ° C and has self-lubricating properties. The normal operating temperature is between 180 ° C and 260 ° C, and it will not cause expansion due to temperature difference. The normal operating temperature of silicon nitride ceramic bearings 800-1000℃, it can be used in high temperature equipment such as furnaces, plastics, and steel.
3. Corrosion resistance: The ceramic thrust bearing material itself has corrosion resistance and can be used in strong acid and alkali inorganic organic salts, seawater and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4. Anti-magnetic: Due to the absence of magnetism and dust absorption, it can reduce the early thrust and noise of ceramic thrust bearings, and can be used in demagnetization equipment, precision instruments and other fields.
5. Electrical insulation: due to high resistance, it can be used for electrical damage to bearings. It can be used in various electronic devices that require insulation.
6. Vacuum: Due to the unique oil-free self-lubricating properties of ceramic materials, silicon ceramic full thrust bearings can overcome the lubrication problems that ordinary bearings cannot achieve in ultra-high vacuum environments.
