Nitrogen Gas Spring
A self-contained cylinder using pressurized nitrogen to deliver high, near-constant force in a small package.
What it means on the floor
Nitrogen gas springs provide very high initial force in a compact cylinder and a flatter force curve than coil die springs. They are used for pressure pads, blank holders, and form stations where space is tight and consistent force is needed.
Force is set by charge pressure and piston area; systems can be plumbed together for synchronized force across a tool.

Applying the term
Interpret Nitrogen Gas Spring in the context of the drawing, governing standard, and customer requirement in front of you — the same word can carry different limits in design, quality, and production documents. Check whether a stated value is nominal, minimum, maximum, or reference-only, and whether it applies before forming, after forming, or after heat treatment.
