●● The main advantages of silicon nitride balls compared to steel balls are:

1. Weighs 59% less than steel balls, significantly reducing the centrifugal force, crushing, and wear on the groove during high-speed and accelerated bearing operation.

2. The modulus of elasticity is 44% higher than that of steel, meaning the deformation is significantly less than that of steel under load.

3. Higher hardness than steel, reaching HRC 78.

4. Low friction coefficient;

5. The coefficient of thermal expansion is 1/4 that of steel, capable of withstanding drastic temperature changes.

6. Achieves nearly perfect surface smoothness with Ra values up to 4-6 nanometers.

7. High Temperature Resistance: Silicon nitride ceramic balls retain high strength and hardness at temperatures up to 1050°C.

8. Rustproof and capable of operation under oil-free lubrication conditions.

9. More resistant to chemical corrosion than steel.

10. Free of metal contamination

11. Non-magnetic;

12. Electrical insulation.

13. No adhesive wear present.

The combination of these superior properties makes silicon nitride an excellent material for high-performance bearing rolling elements.

●●Application:

Silicon nitride ceramic balls are suitable for various bearings with stringent 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 as valve balls and measuring balls in chemical process pumps, high-temperature pumps, and metering pumps.

Silicon nitride ceramic balls are commonly assembled into hybrid bearings and can be applied in high-tech industries such as aviation, as well as widely used in other sectors like chemicals, metallurgy, food, oil fields, and electronics.
