Product Description

Low price, compared with the steel ball, the main advantage of the silicon nitride balls is:
1. 59% lighter than the steel ball, greatly reducing the bearing the high speed and acceleration of channel during operation of the centrifugal force, rolling and wear;
2. Modulus of elasticity is greater than steel, 44% means greatly reduced when the mechanical deformation than ball;
3. Hardness higher than steel, Rc 78;
4. Small friction coefficient;
5. A quarter of the thermal expansion coefficient is steel, able to withstand temperature changes;
6. Accessible, almost perfect surface finish Ra can reach 4 ~ 6 nm;
7. High temperature resistant, silicon nitride ceramic balls in 1050 ° C high temperature still has the very high strength and hardness;
8. Never rust, can work under the condition of oil free;
9. Than steel and chemical corrosion resistance;
10. No metal pollution;
11. Non-magnetic;
12. The electric insulation.
13. There is no adhesive wear;
The excellent performance of the composite makes silicon nitride high-performance rolling bearing material of choice.
Low price, use:
Silicon nitride ceramic balls can be applied to various have extreme performance requirements of bearing, high-speed/ultra high speed bearing, high precision bearing high/low temperature, vacuum bearings, bearings, non magnetic bearings, high precision ball screw;Can also be used in the chemical pump, heat pump, metering pump used for va e ball, ball measurement.
Silicon nitride ceramic balls into a hybrid bearing assembly, can be used in high technology industries such as aerospace, defense industry, also can be widely used in chemical industry, metallurgy, medical, food, oil field, electronics and other industries.
Low price, the company product characteristics: the product performance is stable, good consistency, reach the ASTM F2094-03 - a standard.
Low price, product specifications: 0.4 mm to 100 mm.
Level of low price, can provide: G3 ~ G40.
* * note:

1) is given priority to with the black silicon nitride balls, if necessary, can also provide gray silicon nitride balls.              

2) equipped with a large number of inventory, can meet the delivery requirements at any time.                                        

3) can meet the requirements of various non-standard sizes and gauge value.
