Features:
1. Low density. As the rolling body density decreases, high-speed operation of its centrifugal load is also reduced, which can work at higher speed.
2. Moderate elastic modulus. Elastic modulus is too large due to stress concentration and reduce the bearing capacity of the bushing.
3. Thermal expansion coefficient is small. Reduce the sensitivity to temperature changes, so that the bearing operating temperature range is wider.
4. High compressive strength. High compressive strength is the need for high stress for rolling bearings.
5. High hardness and high toughness. These two properties combine to achieve better surface roughness; and can prevent external particles and shock damage.
6. Good anti-rolling contact fatigue and has a peel failure mode.
7. Special occasions should have high temperature, corrosion resistance and stability.
Applications:
The ceramic material has low density, medium elastic modulus, thermal expansion coefficient is small, high hardness, high temperature, corrosion resistance, non-magnetic, etc., to silicon nitride ceramic ball for the rolling body of ceramic ball bearings can significantly improve the bearing contact fatigue life, Has greatly expanded the application of rolling bearings, has been widely used in a variety of high-precision, high-speed machine tools, automobiles, racing, subway, motor, aero engine, petrochemical machinery, metallurgical machinery and other fields

Boiler Steam header is the main supporting equipment of the boiler to distribute the steam generated by the boiler operation to various pipelines, it also serves as a reservoir that feeds steam to the individual heating circuits. The boiler steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit.
Steam header belongs to the category of pressure vessel, its pressure capacity, volume should be corresponding to the supporting boiler. The main compression elements are head, housing, etc.
