HAHN Gasfedern lockable gas spring, locking over full stroke, elastic and rigid locking

The HAHN Gasfedern lockable gas spring locks continuously over the full stroke. Pressing the release opens a valve in the piston so the rod can be extended or pushed in; when released, the valve closes and the rod stays in the selected position. In elastically locking springs nitrogen passes through the piston, so the locked spring yields slightly and absorbs shocks. In rigidly locking springs oil passes through the piston.

Versions: elastic locking; rigid in tension; rigid in compression (locking force independent of extension force); rigid in tension with low progression for smooth height adjustment; rigid in both directions, including an adjustment element without extension force. In some designs the locking force depends on the filling pressure and is set via a valve.

Release actuation is by the hydraulic HAHN HY release, maintenance-free and adaptable to the chair or table. Materials: steel for high mechanical loads, V2A for humidity, V4A for food and marine environments.

Key features:

• Any position along the stroke, stepless
• Elastic locking absorbs shocks, rigid locking holds precisely
• Hydraulic HAHN HY release without electronics
• Force adjusted via filling valve
• Stainless steel for medical and wet areas

Specifications:

• Locking: continuous over full stroke
• Elastic locking: nitrogen through piston, shock absorption in locked position
• Rigid, tension: locked in tension; compression force depends on pressure
• Rigid, compression: compression locking force independent of extension force
• Low progression: smooth linear height adjustment
• Both directions: locking in compression and tension, version without extension force possible
• Release actuator: hydraulic HAHN HY, maintenance-free
• Material: steel; V2A (AISI 304); V4A (AISI 316)

Application: Office and massage chairs, backrest adjustment, operating and treatment table sections, couches, vehicle and boat seats, height-adjustable tables.

Scope of supply: Lockable spring with agreed end fittings. Release actuator and brackets are separate items.

Before ordering: Before ordering, specify the locking type (elastic or rigid, direction), stroke, required force, release actuator and material.
