1. Automobile
The turbine charger of automobile uses ceramic bearings, which can obtain low temperature rise, reduce the amount of lubricating oil, obtain high speed and good acceleration reactivity, and low torque, low vibration and low temperature rise under high speed rotation.
In addition, rail vehicles will also use the same type of bearings, but the requirements for durability and reliability will be more stringent.
2. Motor
The motor uses ceramic bearings to realize electrical insulation, so as to prevent the bearing from being damaged by electric arc discharge caused by internal leakage when installed in the deceleration or energy-saving device.
3. Aeroengine
In the fuel pump of aeroengine, ceramic bearings can work normally in liquid oxygen, liquid hydrogen and other media. The data shows that they will not be damaged after 50 launches.
4. Aircraft parts
The aircraft flap adjuster can use ball screws with ceramic balls, and the engine of the gas turbine can also use hybrid ceramic bearings.
Motor ceramic bearing
Advantages of ceramic bearings
1. It can be used normally in corrosive working environment.
2. It is not affected by sudden increase and decrease of working temperature.
3. The elastic modulus is higher than that of steel, so it will not be deformed due to stress.
4. The density of ceramic rolling ball is much lower than that of steel, its weight is light, the friction of outer ring is small, and its service life is longer.
