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.
All-ceramic bearings refer to bearings whose rings and rolling elements are made of all-ceramic materials. There are three types: zirconium oxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (SiC). Different materials are matched according to different operating conditions. retainer.
The full-ball all-ceramic bearing adopts a cageless structure design. The bearing is designed with a ball port on one side to facilitate the loading of more ceramic balls, thus improving its load capacity. This design avoids limitations due to retainer materials and improves the corrosion resistance and temperature resistance of all-ceramic bearings. Since this type of bearing has a ball filling gap, this type of bearing is not suitable for use in situations with higher speeds and larger axial loads.
