HAHN Gasfedern GK gas spring with ballpoint-pen locking principle, 10–800 N

The HAHN Gasfedern gas spring with the ballpoint-pen principle (Kugelschreiberprinzip) is a maintenance-free hydropneumatic unit. Nitrogen provides the extension force, and in the free state the rod is extended. A light push, as on a ballpoint pen, locks the rod in the retracted position; the next push releases it and the spring extends by itself. No separate release system (cable, button, hydraulics) is needed, so the unit can be hidden in a drawer, shutter or household appliance.
