Ceramic bearing balls made of high performance ceramic silicon nitride (Si3N4) are produced with tight tolerance and smooth surfaces, they have the best performance among all exsiting bearing balls, especially for critical working environments like high speed, high temperature, high corrosion, silicon nitride bearing balls are irreplaceable. Silicon nitride balls are commonly used in industries such as aerospace, military and defense, hybrid bearings and full ceramic bearings etc.


Compared to bearing balls made of other materials, silicon nitride bearing balls have better friction resistance, higher rigidity, light weight, they are widely to use for high speed or super speed bearings. Because of the excellent self-lubrication property, lubricants are not required for silicon nitride bearing balls, thus will avoid the pollution from lubricating medium. Silicon nitride ceramic bearing balls also have excellent high temperature resistance, the high strength remains up to 800℃,  they are able to work in  environment of strong acid, strong alkali and sea water.

Advantages of Silicon Nitride Bearing Balls



1. It can also be used in corrosion-resistant strong acid, strong alkali and sea water.

2. High temperature resistance, the strength and hardness of the silicon nitride ceramic ball are almost unchanged at 800C.

3. It is not magnetically conductive, insulated, can be used in a magnetic field, and does not conduct electricity.

4. Light weight, 1/4 lighter than ordinary bearings, and its density is 3.20g/cm3.

5. High rigidity, high strength, its hardness is twice higher than that of bearing steel, and its elastic modulus is about 1/3 higher.

6. High-speed rotation, the weight of the rotating body (ball) is light, and the centrifugation is small when rotating.

7. The linear expansion coefficient of the silicon nitride ceramic ball is 3.2×10-6/K, which is almost 1/4 of the bearing steel.

8. The self-lubricity of silicon nitride ceramic bearing balls can solve the pollution and inconvenience of adding lubricating medium.

9. Chemical resistance, mechanical strength, destructive toughness, and low thermal conductivity.
