Push-to-Unlock Gas Springs — Pressure-Release Locking

Push-to-Unlock Gas Springs — Pressure-Release Locking

Compress to the shortest length to lock and press again to release, with no external levers or cables. Configurable force and stroke.

Push-to-Unlock Gas Springs: Features

Built-in Locking Device

Locking engages by compressing the rod to the shortest position and releases with an extra press, without external cables or handles.

Convenient Operation

A simple press down releases the lock and the rod extends at the configured nominal force. No external cables, handles or buttons required.

Space-Saving Design

Does not occupy too much internal space. Ideal for height adjustable desk gas springs, medical beds and styling chairs where external release mechanisms won't fit.

Reliable Performance

Maintains compression state reliably. Suitable for all kinds of situations that need to be locked.

Push-to-Unlock Gas Spring FAQ

What is a push-to-unlock gas spring and how does it work?
It is a lockable gas spring that stays fixed at its shortest length and releases when you push the rod. The bistable mechanism unlocks the spring, which extends to adjust height or position.
Can I customise the force and stroke of a push-to-unlock spring?
Yes. We tailor the locking force (50–650 N), stroke (30–600 mm), extension speed and end fittings to your application. Send your drawing or measurements and we will propose a specification.
Is it suitable for outdoor or corrosive environments?
Yes. We offer AISI 304/316L stainless steel versions with SGS salt-spray resistance of 96–244 h, suitable for marine, agricultural and medical applications.
