Silicon nitride ceramic

Product Details The rings and rolling elements of silicon nitride full ceramic bearings are made of silicon nitride (Si3N4) ceramic material, and the retainers are made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation Made of aluminum, silicon nitride full ceramic bearings have all the characteristics of zirconia ceramic bearings, and are also light weight, high hardness, more wear-resistant, more resistant to high temperatures, etc., and can be used for higher speeds and load capacities, and stronger acid and alkali chemical corrosion , as well as more severe environments and special working conditions, when combined with a full ball, it can be used in high temperature environments above 800°C. With a stainless steel cage, it can be used in temperatures above 450°C. When paired with a PTFE or PEEK cage, it can be used in temperatures above 250°C. Silicon nitride full ceramic bearing product features: 1. High speed: It has the advantages of cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. It can be used in high-speed spindles and other high-precision equipment with a speed of 12,000 rpm to 75,000 rpm. middle; 2. High temperature resistance: The material itself has a high temperature resistance of 1200°C and is self-lubricating. It will not expand due to temperature difference when the operating temperature is between 100°C and 800°C. Can be used in furnaces, plastic making, steel making and other high temperature equipment; 3. Corrosion resistance: The material itself has corrosion resistance and can be used in fields such as strong acid, strong alkali, inorganic, organic salt, seawater, etc., such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc. 4. Anti-magnetic: Because it is non-magnetic and does not absorb dust, it can reduce premature peeling of bearings and loud noise. Can be used in demagnetization equipment. Precision instruments and other fields. 5. Electrical insulation: Due to its high resistance, it can avoid arc damage to the bearings and can be used in various power equipment requiring insulation. 6. Vacuum: Due to the unique oil-free self-lubricating properties of ceramic materials, in ultra-high vacuum environments, silicon nitride all-ceramic bearings can overcome the problem that ordinary bearings cannot achieve lubrication.
