This rubber air spring can be used in many industrial equipment. It plays an indispensable role in industrial equipment.
Improve the isolation and shock absorption capacity of the equipment: Industrial air springs can provide the best degree of isolation and shock absorption that any other shock absorber can't match. A lower natural frequency can be provided by attaching an external gas storage device.
Industrial air springs enable precise height control: AIRSUSTECH Air springs adjust the operating height through internal air pressure. Industrial air springs do not generate static friction with other components. In the case of changes in bearing capacity, the automatic adjustment of system pressure can ensure a stable operating height.
Effectively prevent resonance: The air spring damping system can be designed with two natural frequencies, so resonance can be prevented by switching the natural frequency.
Improve horizontal stability: The air spring has good horizontal stability. Effectively reduce noise: Industrial air springs can reduce structure-transmitted noise. Since it does not have the spring vibration generated in ordinary coil springs, it does not generate noise by itself.
