description
- Firestone air springs are time-proven industrial actuators and vibration isolators. As an actuator, air springs offer a unique ability to provide linear or angular motion in a very low profile when compared to air cylinders. Their unique, flexible properties lend well to numerous duties on machines that press, tension, roll, convey, lift and package. As an isolator, air springs are effective in reducing the harmful effects of vibration.
