Alumina ceramic bearings (Al2O3): Alumina ceramic bearings have good wear resistance, high temperature stability and chemical stability, and are suitable for high-speed and high-temperature environments. Its main models include the 6000 series, 6200 series, 6300 series, etc. Silicon nitride ceramic bearing (Si3N4): Silicon nitride ceramic bearings have high hardness, low thermal expansion coefficient and excellent wear resistance, and perform well under high temperature and high speed conditions. Its main models include the 6000 series, 6200 series, 6300 series, etc. Silicon carbide ceramic bearings (SiC): Silicon carbide ceramic bearings have extremely high hardness, excellent wear resistance and high temperature resistance, and excellent performance in harsh environments. Its main models include the 6000 series, 6200 series, 6300 series, etc. It is worth mentioning that the models of ceramic bearings usually use international standard numbering methods. For example, the 6000 series represents radial deep groove ball bearings, the 6200 series represents slightly different radial deep groove ball bearings with slightly different internal structures, and the 6300 series represents deeper radial deep groove ball bearings, etc. These models cover different sizes, loads and speed requirements to adapt to different mechanical applications. Appropriate ceramic bearing models need to be selected according to specific application requirements and requirements to ensure the performance and reliability of mechanical equipment.
