Shock Control and Vibration Isolation
Air spring isolators are another part of Fabreeka's portfolio. Bellows cylinder air springs, also known as rolling lobe isolators or airbag isolators, provide low frequency vibration isolation for applications requiring high dynamic vibration amplitudes and lifting heights.
Rubber air springs may have vertical and horizontal natural frequencies from 0.6 Hz, depending on operating height, and belted bellows cylinder design (single, double or pneumatic air bellows). Horizontal spring rate, that is the stiffness of the system, and stability also depend on operating height, so each air cushion type has an ideal operating height.
