Type RB

TYPE RB

CFM Air Springs type RB have a natural frequency between 1.2 Hz and 1.5 Hz, depending on size. At an operating pressure of 8 bar, a maximum load capacity of 54.2 kN per air spring can be achieved.

The type RB air spring is primarily used as an isolation element for systems that require a low vertical tuning frequency of 1.2 Hz to 0.9 Hz (with additional volume).

The support housing provides high horizontal stiffness to the air spring. It also serves as a vertical end stop.
