Silicon nitride ceramic bearing
Silicon nitride all ceramic bearing
The ring and rolling element of silicon nitride all ceramic bearing are made of silicon nitride (Si3N4) ceramic material, and the retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum.
Silicon nitride all ceramic bearing product features:
1. High speed: it has the advantages of cold resistance, small stress elasticity, high pressure resistance, poor thermal conductivity, light weight and low friction coefficient. It can be used in high-speed spindle of 12000 RPM ~ 75000 rpm and other high-precision equipment;
2. High temperature resistance: the material itself has high temperature resistance of 1200 ℃ and good self lubrication. There is no expansion caused by temperature difference when the service temperature is between 100 ℃ and 800 ℃. It can be used in high temperature equipment such as furnace, plastic making, steel making, etc;
3. Corrosion resistance: the material itself has the characteristics of corrosion resistance and can be used in strong acid, strong alkali, inorganic, organic salt, seawater and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4. Antimagnetism: because there is no magnetism and no dust absorption, it can reduce the bearing peeling in advance and high noise. It can be used in demagnetization equipment. Precision instruments and other fields.
5. Electrical insulation: due to high electrical resistance, it can avoid arc damage to the bearing and can be used in various power equipment requiring insulation.
6. Vacuum: due to the unique oil-free self-lubricating characteristics of ceramic materials, silicon nitride all ceramic bearings can overcome the problem that ordinary bearings cannot achieve lubrication in ultra-high vacuum environment.
