Principle

The air spring is actually a carefully designed air bag composed of rubber and wire mesh layers, which contains a certain volume of compressed air cylinders. The rubber bladder itself does not provide force or support the load, but rather the air column within it carries the load.

The 2B120-17 can replace the Contitech FD120-17. This product air inlet is G3/4. Also, we have G1/4, G3/8, RC3/8 air hole. We can do as per your requirements. Cause we have dedictiacted to air spring over 10 years.The brand named AIRSUSTECH air bags offer superior quality and performance. As actuators, AIRSUSTECH air springs provide linear or angular motion. As air springs, air springs effectively reduce the harmful effects of vibration.
