Definitions and Operations

A gas spring is a self-contained, hermetically-sealed hydropneumatic linear actuator containing pressurized nitrogen gas, which provides an output force.

SUSPA gas springs offer a unique alternative to conventional mechanical or coil spring lifting or counterbalancing devices. The advantages of these gas springs involve a combination of a relatively flat force curve, controlled forces and extension speed, and damping at the end of the stroke. The spring rate for a gas cylinder is far less than for any mechanical spring.
