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, including zirconium oxide (ZrO2), silicon nitride (Si3N4), and silicon carbide (SiC). Different materials are matched according to different operating conditions. retainer.
The materials commonly used in the production of sliding ceramic bearings and all-ceramic structural parts are zirconia ceramics, silicon nitride ceramics, pressureless sintered silicon carbide ceramics, alumina and other ceramic materials. Sliding ceramic bearings and all-ceramic structural parts of various sizes can be produced according to customer requirements.
