Ceramic bearings refer to the use of high hardness and wear resistant ceramic materials for the raceways and rolling bodies inside the bearings, mainly including alumina ceramics, silicon nitride ceramics, and boron nitride ceramics.
Its principle is to utilize the high hardness and wear resistance of ceramics, which can reduce wear and reduce losses during the use of bearings. Compared with traditional metal bearings, ceramic bearings have the following characteristics:
1. High hardness and wear resistance, reducing wear and friction coefficient;
2. Good temperature resistance, able to maintain stable performance in high-temperature environments;
3. Higher strength enables bearings to have greater load-bearing capacity;
4. Good corrosion resistance and long service life.
Therefore, ceramic bearings are widely used in high-speed, high-temperature, high-pressure, high-precision and special environment fields, such as pneumatic and hydraulic systems, motors, automobiles, machine tools, Op
