With the continuous advancement of processing technology and the increasing level of technology, the cost of ceramic bearings has been declining. It has been applied in a small range of high, fine, and sharp fields from the past, and has been gradually extended to various industrial sectors of the national economy. It is also gradually approaching practicality, reaching a level acceptable to users, and the wave of large-scale application of ceramic bearings has come!
Ceramic bearing use classification
1. High-speed bearings: It has the advantages of cold resistance, low stress elasticity, high pressure resistance, poor thermal conductivity, light weight, low friction coefficient, etc. It can be applied to high-speed spindles of 12,000 rpm-75,000 rpm and other high-precision Equipment.
2. High temperature bearing: The material itself has a high temperature resistance of 1200 ℃, and has good self-lubrication. The use temperature does not produce expansion due to temperature difference between 100 ℃ and 800 ℃. It can be used in high-temperature equipment such as furnaces, plastics, steel, etc.
3. Corrosion-resistant bearings: The material itself has corrosion-resistant characteristics, and can be used in the fields of strong acids, strong alkalis, inorganics, organic salts, seawater, and other fields, such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.
4. Anti-magnetic bearing: Because it is non-magnetic, it does not absorb dust, which can reduce the peeling of the bearing surface, thereby reducing the operating noise. Can be used in demagnetizing equipment. Precision instruments and other fields.
5. Electrically insulated bearings: Due to the high electrical resistivity, the bearings are protected from arc damage and can be used in various electrical equipment requiring insulation.
6. Vacuum bearings: Due to the unique oil-free self-lubricating characteristics of ceramic materials, in the ultra-high vacuum environment, it can overcome the problem that ordinary bearings cannot achieve lubrication.
The above five types of bearings, the same set of bearings can be applied to high temperature, high speed, acid and alkali, magnetic field, non-insulation, but because the material performance is different, please choose the most suitable material according to the application Suitable ceramic bearings.
