Ceramic bearings are mechanical bearings made of ceramic materials such as zirconium oxide, silicon nitride, and silicon carbide.
They are mainly divided into two categories: "all-ceramic bearings," where both the rings and rolling elements are ceramic, and "hybrid ceramic bearings," where only the rolling elements are ceramic.
These bearings possess excellent properties such as resistance to high and low temperatures, corrosion resistance, wear resistance, non-magnetic insulation, and self-lubrication, enabling them to withstand extreme working conditions such as high speed, high temperature, and strong corrosion.
Their manufacturing precision can reach P4 to UP level, and they are widely used in high-tech fields such as aerospace, precision machine tools, wind power generation, medical devices, and new energy vehicles.
my country has made breakthroughs in key technologies such as hot isostatic pressing silicon nitride ceramic balls, achieving the domestic production of high-end ceramic bearings.
