Single Convolution Air Spring Type BZ

With the Single Convolution Air Spring series BZ it is possible to achieve a load capacity of up to 7190 lbf (32 kN) per spring element at a pressure of 87 PSI (6 bar) bar depending on the type. The natural frequencies range from 3.3 to 2.2 Hz These air springs are mainly used for the vibration-isolated mounting of floor plates. For height control please see our level control systems.
