Similarly silicon nitride ceramic bearings have high-temperature resistance, corrosion resistance, wear resistance, oilless self-lubricating, anti-magnetic, insulation, high-speed and other features. si3n4 ceramic bearing is widely used in aviation, aerospace, military, petroleum, chemical, metallurgy, automobiles, electricity, medical equipment and other extremely harsh environments and conditions.
Silicone Nitride is the best ceramic material used for the ceramic bearings.Silicon nitride bearing has the density 3.20g/cm3 ,and is only half weight of zirconia bearings. More light means more speed. Can work in various chemicals.Do not need lubrication, clean, and can wash in the water.Non-magnetic and insulation. Reliable working.Without cage, Constant working in high temperature till 800 Centigrade .Outstanding long time working in low temperature till -80 Centigrade.Tolerance is as per normal bearings. Easy for assembly.
