HAHN Gas & Tension Springs

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 (progression) depending on the diameter of the piston rod and the volume of the cylinder. HAHN gas springs contain an oil filling for lubrication and end damping. These gas springs are available in steel, in AISI 303/304 and AISI 316L/316Ti.

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 road and the inside cylinder diameter is decisive. When no load is applied, the piston rod always is compressed. The tension springs of series 'Z' have no dampint. The series ZD is available with damping and series ZC is available as locking tension spring. HAHN tension springs are available in steel, in AISI 303/304 and AISI 3161/316Ti.
