SUSPA®Updated 2 years ago


SUSPA® Gas springs, also called gas pressure springs, gas dampers or gas pressure dampers, will solve your individual requirements for opening, closing, tilting and damping flaps, tables, seats or loungers thanks to our decades of experience. They take care of the controlled movement sequence and offer the following advantages:

  • Simple installation
  • Compact design
  • Integrated damping
  • Definable spring characteristics and extension speed

The SUSPA® gas spring is filled with non-toxic nitrogen under high pressure. This produces a charging pressure that acts on the cross-sectional area of the piston rod. This generates the extension force. If the extension force of the gas spring is higher than the force of the counterweight, the piston rod extends. If the extension force is lower, then the piston rod retracts. The flow cross-section in the damping system determines how quickly the extension occurs. In addition to nitrogen, there is a defined amount of oil in the interior for lubrication and end position damping. The suspension comfort of a pneumatic spring can be determined as needed and for the respective task.

The SUSPA®  gas spring Liftline is individually designed depending on the installation situation. For us, the focus is on the function of the entire application as well as the individual coordination of the kinematics and the spring characteristics in accordance with the requirements profile. Gas springs are tested in our technical department on systems, test equipment and trial facilities:

  • Linear test benches
  • Folding test benches 
  • Climate test chamber 
  • Hydropulser
  • Tailgate simulation 
  • Speed/acceleration measurement 
  • Laboratory for metallurgy and corrosion tests 

The following conditions are generally considered when selecting the suitable SUSPA®  gas spring: 

  • The ratio of the diameter of the piston rod to the pipe determines the force progression of the spring characteristic. Flat characteristic curves require a small piston rod diameter and a large pipe cross-section.
  • A longer stroke means smaller required forces of the gas spring and in this respect smaller reaction forces at the pivotal points. 
  • A larger piston rod diameter should be chosen for extremely long strokes paired with high extension forces. This solution offers a higher level of safety against the gas spring buckling. Correspondingly, the effect of transverse forces acting on the gas springs should be avoided in general. 

SUSPA®  gas springs correspond to the highest requirements in a variety of application areas due to their basic design and their reliability. However, it is up to the user to check the suitability for the respective application case. We are happy to help you select the appropriate SUSPA® gas spring and install it properly.
