Advantage:

1.Manufacture silicon nitride balls from 1995.

2.The balls are made by Europen silicon nitride powder.

3.Excellent  and stable quality.

4.Plenty of stocks.

Characteristics  of silicon nitride ball:

Their characteristics are shown as follows:

1. High corrosion resistance, which means they can be also used in strong acid, strong alkali and seawater.

2. High temperature resistance. Si₃N₄ ceramic balls remain the same strength and hardness even in 1100°C.

3. Electrical insulation, non-magnetic, they can also be used in magnetic field.

4. Si3N4 ceramic balls have a low density of 3.26g/cm³. It is approximately 60% lighter than steel balls, which extremely decrease the centrifugal force on the groove, in order to effectively reduce the wear and tear.

5. High rigidity and strength. Compared with chrome steel, Si₃N₄ ceramic is twice higher in hardness and half higher in elastic modulus value.

6. The coefficient of thermal expansion of Si₃N₄ is nearly 25% of the chrome steel, which leads to a good thermal shock resistance.

7. The self-lubrication of Si₃N₄ ceramic ball bearings can help to solve the contamination and inconvenient caused by lubricator, it can also be used in vacuum and high temperature.

8. Low thermal conductivity.

Grade of ceramic balls:

Application fields:

High precise ceramic bearings, high temperature bearings, vacuum bearings, nonmagnetic bearings, chemical pump, high temperature pump, ceramic valve ball, measure ball.

   Carton box,with vacuum package.

 Silicon nitride ceramics research and production began in the 1970s.It is the first unit in China. The company obtained more than twenty ministerial-research- achievement awards, and 18 patents in the nitride silicon ceramic field. Our technology and production strength are in the leading position in China. 

The company has advanced production including a HIP furnace and improved detection equipment and strictly follow the ISO9001 quality system.
