Characteristics of air springs:

1. Long service life, self-sealing type has excellent durability due to less rubber deformation during expansion and contraction.

2. The maintenance is very simple, there is no friction sliding part, so there is no need to add lubricating oil.

3. The installation height can be reduced. Compared with other springs, the installation height can be reduced and the stroke can be effectively increased.

4. The elastic and soft spring parameters can be obtained, the load is large and the elasticity is soft, and the anti-vibration performance is excellent.

5. The output of bearing capacity is variable, and the bearing capacity can be changed in a wide range by changing the internal pressure.

6. The height can be controlled, if used together with the height adjustment valve, it can maintain a constant height for different loads.

7. It has a damping effect. If it is used together with an auxiliary air chamber and a throttle valve, an excellent damping effect can be obtained, thereby reducing the resonance amplitude.

8. Easy to install, simple structure, easy to install and dismantle.
