Ceramic bearings have characteristics such as high temperature resistance, cold resistance, wear resistance, corrosion resistance, magnetoelectric insulation, oil-free self-lubrication, and high rotational speed. It can be used in extremely harsh environments and special working conditions, and can be widely used in aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, national defense and military fields. It is a high-tech product for the application of new materials.
The rings and rolling elements of ceramic bearings are made of all ceramic materials, including zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic). The retainer is made of polytetrafluoroethylene, nylon 66, polyether amide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thus expanding the application of ceramic bearings.
In the fields of aerospace, navigation, nuclear industry, petroleum, chemical industry, light textile industry, machinery, metallurgy, electricity, food, locomotives, subways, high-speed machine tools, and scientific research, national defense and military technology, it is necessary to work under special working conditions such as high temperature, high speed, deep cold, flammable, explosive, strong corrosion, vacuum, electrical insulation, non magnetic, and dry friction. The indispensable replacement role of ceramic bearings is gradually being recognized by people.
With the continuous progress of processing technology and the increasing level of craftsmanship, the cost of ceramic bearings continues to decrease. They have gradually been applied in small areas of high, precision, and cutting-edge industries in the past, and gradually promoted to various industrial fields of the national economy. The product market prices are also gradually approaching practicality, reaching a level acceptable to users. The wave of large-scale application of ceramic bearings has surged!
