Product Description

Product Description

 

Silicon Csrbide ceramic balls:

Ceramic balls are particularly versatile and most widely usage. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. And we can offer neutral and customized services. So our customers say our bearings are high quality and reasonable price.

Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent
thermal conductivity, low thermal expansion, and is resistant to corrosion from acids. Silicon carbide is an excellent ceramic
material for applications requiring good erosion and abrasive resistance.

 

 
Compared with steel balls, the main advantages of silicon carbide balls are:

1. It is 59% lighter than steel balls, which greatly reduces the centrifugal force, rolling and wear on the channel when the bearing is running at high speed and acceleration;
2. The hardness is higher than steel, with HV reaching 2500;
4. Small friction coefficient;
5. The thermal expansion coefficient is 1/4 of steel and can withstand drastic changes in temperature;
6. It is easy to obtain almost perfect surface finish, Ra can reach 4 to 6 nanometers;
7. High temperature resistance: Silicon carbide ceramic balls still have high strength and hardness at a high temperature of 1650°C;
8. 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;

Use:
Silicon carbide ceramic balls can be used for grinding various powder materials and various precision bearings.
Silicon carbide ceramic balls are generally assembled into hybrid bearings and can be used in high-tech industries such as aviation, defense and other industries. They can also be widely used in chemical industry, metallurgy, medical, food, oil fields, electronics and other industries.
