As an important mechanical component, ceramic bearings have been widely used in various fields because of their excellent performance that metal bearings cannot match. According to the application, ceramic bearings can be divided into the following categories:

High speed bearings

High-speed bearings have the advantages of cold resistance, small force elasticity, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. They can be used in high-speed spindles from 12,000 rpm to 75,000 rpm and other high-precision equipment.

High temperature bearing

The material itself has a high temperature resistance of 1200 ° C, and is self-lubricating, and the use temperature is between 100 ° C and 800 ° C without expansion caused by temperature difference. It can be used in furnaces, plastics and steel high temperature equipment.

Corrosion Resistant Bearings

The material itself has the characteristics of corrosion resistance and can be used in strong acid, strong alkali, inorganic, organic salt, seawater and other fields, such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

Antimagnetic bearing

Because there is no magnetism and no dust absorption, it can reduce the bearing peeling off in advance and the noise. Can be used in demagnetization equipment. Precision instruments and other fields. Antimagnetic bearings can be used in the fields of demagnetization equipment, precision instruments, etc.

Electrically insulated bearings

Due to its high electrical resistance, it can avoid arc damage to the bearing and can be used in various electrical equipment requiring insulation.

Vacuum bearing

Due to the unique oil-free self-lubricating properties of ceramic materials, it can overcome the problem that ordinary bearings cannot achieve lubrication in an ultra-high vacuum environment.
