  Descriptions: The ceramic ball is a high-grade silicon nitride ceramic ball with a very bright appearance, a high level of precision, and a wide range of uses, such as: all-ceramic bearings, hybrid ceramic bearings, tools and measuring tools, valve seals, pumps, and more.
The main advantages of silicon nitride balls compared to steel balls are:
1. It is 59% lighter than steel balls, greatly reducing the centrifugal force, rolling and wear of the groove during high-speed and accelerated operation of the bearing.
2. The modulus of elasticity is 44% larger than that of steel, which means that the amount of deformation is greatly reduced when subjected to force than that of steel balls.
3. The hardness is higher than that of steel, with HRC reaching 78.
4. Small friction coefficient.
5. The coefficient of thermal expansion is 1/4 that of steel, capable of withstanding sudden changes in temperature.
6. It is easy to obtain a high surface finish, with Ra reaching 4 to 6 nanometers.
7. High temperature resistance: Silicon nitride ceramic balls still have high strength and hardness at 1050 ° C.
8. It will never rust and can work without oil lubrication.
9. More resistant to chemical corrosion than steel.
10. No metal pollution.
11. Non-magnetic;
12. Electrical insulation.
13. There is no adhesive wear.
The combination of these outstanding properties makes silicon nitride the first choice for high-performance bearing rolling element materials.
Purpose:
Silicon nitride ceramic balls can be used for a variety of bearings with extreme performance requirements: high-speed/ultra-high-speed bearings, high-precision bearings, vacuum bearings, high/low-temperature bearings, non-magnetic bearings, and high-precision ball screws; they can also be used in chemical pumps, high-temperature pumps, and metering pumps.
Silicon nitride ceramic balls are typically assembled into hybrid bearings, which can be used in high-tech industries such as aviation, national defense, and other industries. They can also be widely used in chemical, metallurgical, medical, food, oilfield, electronics, and other industries.
