Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, electromagnetic insulation resistance, oil-free self-lubrication and high speed. It can be used in extremely harsh environment and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical devices, scientific research, national defense and military fields. It is a high-tech product of new material application. The rings and rolling bodies of ceramic bearings are made of all ceramic materials, including zirconia (ZrO2 _ 2), silicon nitride (SisN4 _ 4) and silicon carbide (Sic). The cage is made of PTFE, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, which expands the application of ceramic bearings.
Application fields: medical instruments, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery, food processing machinery.
