Advantages of Ceramic Bearing Materials

In recent years, ceramic bearings have been increasingly used in various fields, such as aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, power, textiles, pumps, medical equipment, scientific research, and national defense and military. The advantages of using ceramic bearings in new products are becoming increasingly apparent. The following is a specific understanding of the advantages of using ceramic bearing materials.

The advantages of ceramic bearing materials mainly include the following:

1. High speed: Ceramic bearings have advantages such as cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, and low friction coefficient. They can be used in high-speed spindles and other high-precision equipment ranging from 12000 rpm to 75000 rpm;

2. High temperature resistance: Ceramic bearing materials themselves have high temperature resistance of 1200 ℃ and good self-lubricating. They do not cause expansion due to temperature differences when used between 100 ℃ and 800 ℃. Can be applied in high-temperature equipment such as furnaces, plastics, and steel making;

3. Corrosion resistance: Ceramic bearing materials themselves have the characteristic of corrosion resistance and can be applied in fields such as strong acid, strong alkali, inorganic, organic salt, seawater, etc., such as electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

4. Anti magnetic: Ceramic bearings, due to their lack of magnetism and dust absorption, can reduce premature bearing peeling and loud noise. Can be used on demagnetization devices. Precision instruments and other fields.

5. Electrical insulation: Ceramic bearings, due to their high electrical resistance, can avoid arc damage to the bearings and can be used in various power equipment that requires insulation.

6. Vacuum: Due to the unique oil-free self-lubricating characteristics of ceramic materials, silicon nitride all ceramic bearings can overcome the problem of lubrication that ordinary bearings cannot achieve in ultra-high vacuum environments.
