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 × 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.

| 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 ° 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.
