In recent years, ceramic bearings have been used in more and more fields, such as aviation, aerospace, navigation, petroleum, chemical industry, automobiles, electronic equipment, metallurgy, electric power, textiles, pumps, medical equipment, scientific research, and national defense and military fields. Ceramic bearings are now more and more obvious in the use of new products. China Bearing Network will tell you what are the advantages of using ceramic bearing materials based on specific understanding.
The advantages of ceramic bearing materials mainly include the following:
1. High speed: Ceramic bearings have the advantages of cold resistance, small elasticity under force, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. In precision equipment;
2. High temperature resistance: The ceramic bearing material itself has a high temperature resistance of 1200°C, and is self-lubricating. The operating temperature does not cause expansion due to temperature difference between 100°C and 800°C. It can be used in high temperature equipment such as kiln, plastic making and steel making;
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 are non-magnetic and do not absorb dust, which can reduce the premature peeling of the bearings and loud noises. Can be used in demagnetization equipment. Precision instruments and other fields.
5. Electrical insulation: Due to the high resistance of ceramic bearings, it can avoid arc damage to the bearings, and can be used in various electrical equipment requiring insulation.
6. Vacuum: Due to the unique oil-free self-lubricating properties of ceramic materials, in an ultra-high vacuum environment, silicon nitride full-ceramic bearings can overcome the problem that ordinary bearings cannot achieve lubrication.
