What are stainless steel gas springs?

Stainless steel gas springs are mechanical devices that use compressed gas to provide smooth, controlled force, typically to lift, lower, or support a moving part.

These sealed, nitrogen-filled struts are constructed with stainless steel components for enhanced durability and corrosion resistance in harsh environments, such as those found in marine, medical, and food production applications.

How do stainless gas springs work?

Stainless steel gas springs use compressed nitrogen gas sealed inside a corrosion-resistant cylinder to provide smooth, controlled force for lifting, lowering, or holding loads. As the piston rod moves, the gas pressure creates a pushing force, while internal valves regulate the motion, with the gas charge and piston area determining the force. Their stainless steel construction and high-quality seals make them ideal for harsh, hygienic, or outdoor environments. Lockable versions offer secure positioning under load.

Stainless steel gas spring material grades

Lesjöfors supplies stainless steel gas struts for corrosive and hygienic environments. Many use 316 or 316L-grade components for superior resistance. Precision rod finishes, high-performance seals, and compatible lubricants add wear resistance. They also improve cleanability and extend service life in marine and food applications.
