Silicon nitride (Si3N4) all ceramic bearing



The ferrule and rolling body of silicon nitride all ceramic bearing are made of silicon nitride (Si3N4) ceramic material, and the retainer is made of polytetrafluoroethylene, nylon 66, polyether acyl ammonia, zirconia, silicon nitride, stainless steel or special aviation aluminum.


< P style = 'text indent: 0;' > < b > product features of silicon nitride all ceramic bearing:


1. High speed: it has the advantages of cold resistance, small stress elasticity, large pressure resistance, poor thermal conductivity, light self weight, small friction coefficient, etc. it can be applied to the high-speed spindle and other high-precision equipment of 12000 RPM ~ 75000 rpm


2. High temperature resistance: the material itself has a high temperature resistance of 1200 ℃ and good self-lubricating. The use temperature is between 100 ℃ - 800 ℃ without expansion caused by temperature difference. It can be used in furnace, plastic, steel and other high temperature equipment


3. Corrosion resistance: the material itself has the characteristics of corrosion resistance, which can be applied in the fields of strong acid, strong alkali, inorganic, organic salt, sea water, etc., 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 the noise. It can be used in demagnetization equipment. Precision instruments and other fields.


5. Electrical insulation: due to high electrical resistance, the bearing can be free from arc damage and can be used in various electrical 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.
