According to different ceramic materials, ceramic bearings can be divided into the following types:
1. Alumina ceramic bearings: Alumina ceramic is currently one of the widely used ceramic materials, and its high hardness, low wear rate, and high strength make it the main choice for manufacturing ceramic bearings.
2. Silazane ceramic bearings: Silazane ceramics have excellent hardness and wear resistance, as well as good thermal and corrosion resistance, making them suitable for bearings in high-temperature, high-speed, high load, and highly corrosive environments.
3. Boron nitride ceramic bearings: Boron nitride ceramic is a new type of high-performance ceramic material with high hardness, strength, and thermal stability, making it very suitable for bearings in high-temperature, high-speed, high load, and highly corrosive environments.
4. Silicon carbide ceramic bearings: Silicon carbide ceramic materials have advantages such as high hardness, high strength, and good wear resistance, especially suitable for bearings in high-temperature and high-speed environments.
In practical applications, different types of ceramic bearings have their own advantages and disadvantages, and the selection should be based on the specific application environment and requirements.
