Design and function of HAHN gas springs HAHN gas springs are used for all applications that require controlled moving and braking of weights without having to apply strong forces. Gas springs by HAHN are used in virtually every field today. In furniture industry, engineering, for sports, leisure and home appliances, in medical engineering and other areas of industrial and private use. For special applications in medical engineering, the chemicals and food industry and shipbuilding, we manufacture our products in stainless steel. We produce all types and series in AISI 303/304 and AISI...

Step 1: Selection of the product G = Gas spring Z = Tension spring ZD = Tension spring with damping ZX = Locking tension spring F = Elastic locking gas spring S = Rigid locking gas spring X = Absolutely rigid locking gas spring SL = Free-moving locking gas spring SX = Double rigid locking gas spring D = Preset oil damper Order system Step 2: Select a series on the basis of the required force, the desired stroke and the maximum installation length. Step 3: Enter the desired stroke in mm. Step 4: Select the damping (1= with, 0 = without damping, 9 = special nozzel) or the braking direction...

HAHN Gasfedern provides several decades of experience in gas spring technology. The first HAHN gas springs were already developed and produced in 1966. Today we manufacture 17 different series in steel and stainless steel AISI 303/304 and AISI 316L/316Ti. The HAHN modular system provides more than 5 million variants. At the same time, we are the manufacturers of the smallest gas spring in the world, market leaders in the sector of stainless-steel gas springs and the only manufacturers of special series such as double-stroke and telescopic gas springs.

Design and function of HAHN gas springs Base plate Nitrogen Sealing HAHN gas springs are hydropneumatic, closed and maintenance-free adjustable elements. The spring force F1 results from the internal pressure (160 bars without load at the most) in the cylinder, which is generated by the filling medium nitrogen. On the gas spring, this pressure is applied to the cross-section of the piston rod. When no load is applied, the piston rod always is extended. By pushing in the piston rod, the volume in the cylinder is reduced, and the gas is compressed. Thus the gas spring force increases...

Tension springs

HAHN tension springs are used for all applications where normal gas springs cannot be used for lack of space. Tension springs work in the opposite way as gas springs, i.e. the piston rod is pulled towards the inside by means of the gas pressure in the cylinder. The spring force F1 results from the internal pressure (160 bars without load at the most) in the cylinder, which is generated by the filling medium nitrogen. In the tension spring, the piston ring area between the piston rod and the inside cylinder diameter is decisive. When no load is applied, the piston rod always is compressed....

HAHN locking gas springs can be locked steplessly along the complete stroke. Furniture, vehicle seats, flaps, etc. can be locked in the desired position and readjusted. When the release is actuated, the piston valve opens. In the elastic locking gas springs it is nitrogen, in the rigid locking gas springs it is oil that flows through the piston, and the piston rod is extended or can be pushed in. When the release is actuated, the valve in the gas spring closes automatically, and the piston rod is locked in the desired position. HAHN Gasfedern adjusts the locking type exactly to the...
