Ceramic Ball—Silicon Nitride Ball
Clean room universal ball series
The main advantages of silicon nitride balls compared to steel balls are:
2. The modulus of elasticity is 44% larger than that of steel, which means that the deformation is much less than that of steel balls when subjected to force;
3, the hardness is higher than steel, HRC reaches 78;
4, the friction coefficient is small;
5, the thermal expansion coefficient is 1/4 of steel, able to withstand temperature drastic changes;
6, easy to get almost perfect surface finish, Ra can reach 4-6 nm;
7, high temperature resistance: silicon nitride ceramic ball still has high strength and hardness at 1050 ° C high temperature Degree;
8, never rust, can work under oil-free lubrication conditions;
9, more resistant to chemical corrosion than steel;
10, no metal pollution;
11, no magnetic;
12, electrical insulation.
13. There is no adhesive wear;
14. It does not stick to the metal melt at high temperature and hardly reacts;
The combination of these excellent properties makes silicon nitride a high-performance bearing rolling element and a high-performance valve ball. The material of choice.
