SI3N4 Ceramic Ball With 3800 MPa Compressive Strength And 7 MPa Fracture Toughness
SI3N4 Ceramic Ball With 3800 MPa Compressive Strength And 7 MPa Fracture Toughness
Product Description:
Silicon Nitride Ceramics are a superior choice for a wide range of industrial applications due to their excellent thermal and electrical properties, high strength-to-weight ratio, and superior wear resistance. These ceramics are composed of the unique and highly stable silicon nitride (Si3N4) compound, which can be formed into a variety of shapes and sizes. Our Silicon Nitride Ceramics are renowned for their outstanding performance, with a density of 3.2 g/cm3, fracture toughness of 7 MPa, dielectric constant of 9, hardness of 13.9 GPa, and Poisson's ratio of 0.27. These unique properties make Silicon Nitride Ceramics the ideal choice for a variety of applications, including SI3N4 ceramic balls used in bearings, valves, and other industrial components.
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.
