Silicon nitride ceramic bearings self-lubrication high precision non conducting insulation waterproof

product name:Silicon nitride ceramic bearings

product description:

Bearing is the soul of all rotating machinery, known as the ' chip ' of the mechanical industry. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
Silicon nitride material is commonly known as ' ceramic king '. Its density is about 42 % of bearing steel, its elastic modulus is as high as 320 GPa, its tensile strength is 1600 MPa, its compressive strength is as high as 3600 MPa, and its mechanical properties are almost unchanged below 900 °C. It is one of the ideal materials for rolling bearings. Silicon nitride ceramic ball bearing is the most popular, most excellent and most widely used high-end ceramic bearing in the world, which is almost synonymous with ceramic bearing.
Main purposes :
Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic insulation, oil-free self-lubricating, high speed and so on. It can be used in extremely harsh environments and special working conditions. It can be widely used in aerospace, aviation, navigation, petroleum, chemical industry, automobile, electronic equipment, metallurgy, electric power, textile, pump, medical equipment, scientific research and national defense and military fields. It is a high-tech product for the application of new materials.
