High Strength Ceramic Si3N4 Silicon Nitride mill Ball

5. High rigidity and high strength. The hardness is twice as high as the bearings steel ball while the elastic modulus is half of that. 6. The linear expansion coefficient of the silicon nitride ceramic ball is 3.2 10-6/K, almost 1/4 of the bearings steel, which is able to withstand sudden change of temperature. 7

Si3N4 ceramic ball . Si3N4 is a new bearing ball material with features of high temperature resistance, corrosion resistance, electrical insulation, non-magnetism, high strength, low density. In the application of bearing, the bearing can implement the performance of high speed, high precision, high temperature, high rigidity, corrosion resistance

HIP Silicon Nitride (Si3N4) Ball. Silicon nitride is a hard ceramic having high strength over a broad temperature range, moderatethermal conductivity, low coefficient of thermal expansion,moderately high elastic modulus, and unusually high fracture toughness for a ceramic. This combination of properties leads to excellentthermal shock

Silicon Nitride Ceramic Description. Silicon nitride (Si3N4) is a high-melting-point ceramic material that is extremely hard and relatively chemically inert. Si3N4 is as light as silicon carbide (SiC), but has excellent thermal shock resistance. Its high fracture toughness makes it resistant to impacts and shocks

Silicon nitride ceramic has low thermal expansion coefficient, high thermal conductivity and excellent thermal shock resistance.In the very high temperature, silicon nitride keeps a high strength and impact resistance. As an excellent high temperature engineering materials, silicon nitride ceramics are “super hard” providing a high mechanical strength, outstanding wear and very good acid

Silicon Nitride (Si 3 N 4) has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance

Ceramic balls made of silicon nitride (Si3N4) exhibited excellent mechanical properties are used in high-end components operating at ultra-high speeds, and high and low temperatures

14 rows Si3N4 ceramic ball. Silicon nitride ceramic (Si3N4) is a new kind of bearing material with

Silicon Nitride (Si3N4) Basic Information. Silicon nitride ceramic is an inorganic ceramic material. Silicon nitride is very strong, especially hot-pressed silicon nitride, which is one of the hardest materials in the world. It has the properties of high strength, low density

A silicon nitride bearing is only 40% of the weight of its steel equivalent. As full ceramic Si3N4 bearings have high hardness, very smooth wear surfaces and are generally supplied without lubrication, they are often used in applications that require extremely low turning resistance. Full ceramic bearings have a very low coefficient of friction compared to steel bearings or even hybrid bearings
