Ceramic bearings have characteristics such as high temperature resistance, cold resistance, wear resistance, corrosion resistance, resistance to magnetic and electrical insulation, oil-free self-lubricating, and high speed. Can be used in extremely harsh environments and special working conditions, and can be widely applied in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, and moreMedical devices, low-temperature engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinerywaitThe field needs to work under special working conditions such as high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electrical insulation, non-magnetic, dry friction, etc. The indispensable substitute role of ceramic bearings is gradually being recognized by people.It is a high-tech product for the application of new materials.
