Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, antimagnetic electrical insulation, oil-free self-lubricating, high speed, etc. Can be used in extremely harsh environments and special working conditions. Due to these characteristics of ceramic bearings, ceramic bearings are widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, metallurgy, electric power, textile, pumps, medical equipment, scientific research and national defense and military fields.
In addition to the properties of zirconia, silicon nitride full ceramic bearings also have the characteristics of light specific gravity, good wear resistance and high hardness. Compared with ceramic bearings made of zirconia material, all-ceramic bearings made of silicon nitride material are more suitable for high-speed, high-load capacity and higher-temperature occasions. At the same time, silicon nitride material has good high-temperature strength, mechanical oxidation resistance, and high-temperature load-bearing ability. Ability and good resistance to strong acids and alkalis.
All-ceramic bearings refer to bearings whose rings and rolling elements are made of all-ceramic materials, including zirconium oxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (SiC). Different materials are matched according to different operating conditions. retainer.
