We can't live without some mechanical equipment, because it is also a part of our life. Bearing is an important basic component of machinery and so on. However, there are many materials of bearing. Different materials are suitable for different mechanical equipment. Ceramic bearing may not be well understood by all of you. Let's introduce the advantages and disadvantages of ceramic bearing to you?

1、 What are the uses of ceramic bearings

1, automobile

The bearing used in automobile has the highest requirement for speed, which is the bearing of turbo charger. The bearing is required to have good acceleration reactivity, low torque, low vibration and low temperature rise under high-speed rotation. Because of its low temperature rise in operation, it can reduce the amount of lubricating oil, so the mixing resistance of oil is reduced, the bearing torque is reduced, and the speed is increased. In addition, rail vehicles also use it, and its durability and reliability under harsh conditions have been confirmed.

2. Motor

When the motor is used for deceleration and energy-saving devices, the internal leakage can cause the phenomenon of arc discharge.

3. Aeroengine

In the fuel pump of aeroengine, it can work in the medium of liquid oxygen and liquid hydrogen for a long time. It has been proved that it has experienced 50 launches without damage.

4. Aircraft parts

In the aircraft manufacturing industry, ball screws with ceramic balls have been used in the flap regulators of aircraft, and hybrid ceramic bearings have also been used in the engines of gas turbines.

2、 Advantages of ceramic bearing

1. It has the advantage of zero corrosion. It can be used without obstacles even in the working environment with dissatisfaction with corrosion.

2. Whether the temperature suddenly rises or falls, it can be unaffected.

3. The biggest characteristic of ceramic bearing is that it will not deform because of the force, because the elastic modulus of bearing is higher than that of steel.

4. The density of ceramic rolling ball is much lower than that of steel, so the weight is much lighter naturally. Therefore, the friction of rotating outer ring centrifugal can be reduced, and the service life of natural ceramic bearing will be longer.

In conclusion:

Advantages of ceramic bearing: it can be used in high temperature, insulation, corrosion resistance and non lubrication occasions.

Disadvantages of ceramic bearing: difficult processing and high cost.
