Ceramic bearing

In recent years, ceramic bearings have been used in more and more fields, such as aviation, aerospace, navigation, petroleum, chemical, automotive, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research, national defense and military fields. Nowadays, the advantages of using new products of ceramic bearings are becoming more and more obvious. Tell everyone about the advantages of using ceramic bearing materials.

The advantages of ceramic bearing materials are mainly as follows:

1. High speed: Ceramic bearings have the advantages of cold resistance, small force elasticity, high pressure resistance, poor thermal conductivity, light weight, and low friction coefficient. They can be applied to high-speed spindles of 12,000 rpm to 75,000 rpm and other high-speed spindles. Precision equipment;

2. High temperature resistance: The ceramic bearing material itself has a high temperature resistance of 1200°C and is self-lubricating. The use temperature is between 100°C and 800°C without expansion due to temperature differences. It can be used in high temperature equipment such as furnace, plastic making, steel making, etc.;

3. Corrosion resistance: The ceramic bearing 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.

4. Anti-magnetic: Ceramic bearings do not absorb dust because they are non-magnetic, which can reduce the bearing peeling off in advance and loud noise. Can be used in demagnetization equipment. Precision instruments and other fields.

5. Electrical insulation: ceramic bearings can avoid arc damage due to high electrical resistance, and can be used in various electrical equipment requiring insulation.

6. Vacuum: Because of the unique oil-free and self-lubricating characteristics of ceramic materials, the silicon nitride full ceramic bearing can overcome the problem that ordinary bearings cannot achieve lubrication in an ultra-high vacuum environment.
