product name:Silicon nitride ceramic bearings

Compared with steel balls, the main advantages of silicon nitride balls are :
1, 59 % lighter than the steel ball, which greatly reduces the centrifugal force, rolling and wear of the channel when the bearing is running at high speed and acceleration.
The elastic modulus is 44 % larger than that of steel, which means that the deformation is much less than that of steel ball.
The hardness is higher than that of steel, and the HRC reaches 78 ;
4, the friction coefficient is small ;
5, thermal expansion coefficient is 1 / 4 of steel, can withstand temperature change ;
6.It is easy to obtain a higher surface finish, Ra can reach 4 ~ 6 nm ;
7.High temperature resistance : Silicon nitride ceramic balls still have high strength and hardness at 1050 ° C ;
8, never rust, can work under the condition of oil-free lubrication ;
9. More resistant to chemical corrosion than steel ;
10, no metal pollution ;
11, non-magnetic ;
12. Electrical insulation.
13, there is no adhesion wear ;
the combination of these excellent properties makes silicon nitride the preferred material for high-performance bearing rolling elements.

Uses :
Silicon nitride ceramic balls can be used for a variety of bearings with ultimate performance requirements : high-speed / ultra-high-speed bearings, high-precision bearings, vacuum bearings, high / low-temperature bearings, non-magnetic bearings, high-precision ball screws ; it can also be used in chemical pumps, high temperature pumps, and metering pumps as valve balls, swimming valves, fixed valves, and measuring balls.
Silicon nitride ceramic balls are generally assembled into hybrid bearings, which can be used in high-tech industries such as aviation, national defense and other industries, and can also be widely used in chemical, metallurgical, medical, food, oil fields, electronics and other industries.
