Gas spring is a pressure pneumatic accessory. They consist of a steel tube and a piston rod with a piston unit. Connecting elements on the steel tube and piston rod provide the appropriate connection for your application.

The gas spring is filled with non-toxic high-pressure nitrogen. This creates inflation pressure, which acts on the cross-section of the piston rod, creating a stretching force. If the extension force of the gas spring is greater than the balancing force, the piston rod will extend; otherwise, the piston rod will extend. If the extension force is small, retract. The speed of extension is determined by the flow cross-section in the damping system.
