Silicon Nitride Ceramic Ball

Silicon Nitride Ceramic Ball are spherical objects made from high-performance silicon nitride as the raw material through processes such as high-temperature sintering of powder. After a series of fine processing operations, they eventually form silicon nitride ceramic balls with high precision and high grade. The precision of the silicon nitride ceramic balls we produce can reach up to G5.

Silicon nitride ceramic balls are popular because they possess a series of outstanding properties that far exceed those of traditional steel balls.
1.Low density
This means that when rotating at high speed, the centrifugal force generated is much smaller, thereby significantly reducing the frictional resistance and temperature rise of the bearing, and greatly increasing the maximum rotational speed.

2.High hardness
The hardness is much higher than that of bearing steel. This gives it extremely high wear resistance and its service life is much longer than that of steel balls.

3.Resistant to high temperatures

It can maintain stable performance even at extremely high temperatures of up to 800°C or even 1200°C (depending on the grade).

4.Self-lubricating property
Silicon nitride material itself has certain self-lubricating properties. Even in conditions of poor lubrication or low oil content, it can still maintain a certain working ability and has good anti-sticking performance.

5.Corrosion-resistant
It has excellent resistance to most chemical substances such as acids and bases, and can operate in highly corrosive media. In contrast, steel balls will rust and corrode.

6.Electrical insulation property
It is an excellent electrical insulator.

7.Non-magnetic
Not affected by magnetic fields, it is suitable for instruments and equipment that require a completely non-magnetic environment, such as medical MRI equipment and high-precision scientific research instruments.
