Products Description

Si3N4: 1, corrosion-resistant strong acid, alkali, seawater can also be used. 2, high temperature, ultra-wear-resistant, silicon nitride ceramic ball at 8000C, the strength, hardness almost unchanged. 3, non-magnetic, insulation, magnetic field can also be used, non-conductive. 4, light weight, lighter than the average material bearing 1/4, the density of 3.20g / cm3. 5, high rigidity, high strength, the hardness of the bearing than the double, elastic modulus of about 1/3. 6, high-speed rotation, rotating body (ball) light weight, small centrifugal rotation. 7, silicon nitride ceramic ball linear expansion coefficient of 3.2 Ã? 10-6 / K, almost 1/4 of bearing steel. 8, silicon nitride ceramic ball bearing self-lubricating can solve the lubrication caused by pollution and add inconvenience. 9, drug resistance, mechanical strength, damage toughness, low thermal conductivity. Application areas: composite bearings, mechanical seals, chemical pumps, nozzles, auto parts, heat exchanger parts, vacuum equipment and other harsh environments. PRODUCT SILICON NITRIDE BALLS(Si3N4) DIAMETER Î¦0.5mmâ??Î¦80.0mm GRADE G5-G25 PERFORMANCE 1,59% lighter than the ball, which means less centrifugal force and wear less groove at high speed and acceleration. 2, 44% of the modulus of elasticity, which means less load deformation. 3, Rockwell hardness 92 4, the smaller the coefficient of friction 5, only 1/4 of the thermal expansion coefficient of steel, you can tolerate high temperatures. 6, can achieve excellent surface finish, Ra can be 4 to 6. 7, can withstand high temperature and high hardness and strength up to 1050 Â° C 8, never rust, can be no lubricant. The 9, more resistant to corrosion than steel. APPLICATION Silicon nitride ceramic ball can be used for a variety of bearing performance requirements: high-speed / ultra-high-speed bearings, high precision bearings, vacuum bearings, high / low temperature bearings, non-magnetic bearings, high precision ball screw; , High temperature pump, metering pump used as a ball, measuring the ball. Silicon nitride ceramic ball is generally assembled into a hybrid bearing, can be used in high-tech industries such as aviation, defense and other industries, can also be widely used in chemical, metallurgical, medical, food, oil, electronics and other industries.
