Shock absorbers and vibration dampers

Our dampers differ in pipe diameter, piston rod diameter, force classes and in different designs:

HD 1313 mm5 mm50 - 400 N
HD 1515 mm  6 mm50 - 500 N
HD 1818 mm  8 mm

HD 3434 mm  8 mm100 - 5,000 N
HD 3838 mm10 mm100 - 6,000 N


These sizes are also available by request with a path-dependent damping. The path-dependent damping is the change across the path at constant speed. It should be noted that the force classes (damping forces) may change at higher test speeds.

The sizes named in the table above are available with the following models depending on the application:

  • Standard damper

    The standard damper is suitable for versatile applications. A compensation chamber remains in the pressure pipe for the retracting piston rod. An idle stroke may result here depending on the installation position.

     

    Characteristics

    • Without extension force F1
    • With idle stroke
    • Positionally-dependent

     

    Application Examples

    • Waste containers
    • Shop counter
    • Medical applications
    • Furniture flaps
    • Commercial vehicle interior
    • Overhead compartment
    • Seats for commercial vehicles
  • Dampers with gas pressure (GD)

    The damper with gas pressure corresponds to the standard damper, but with extension force.

     

    Characteristics

    • With extension force F1
    • With idle stroke
    • Positionally-dependent

     

    Application Examples

    • Industrial applications
    • Seats for commercial vehicles
  • Dampers with gas pressure and separating piston (GDTK)

    For dampers with gas pressure and separating pistons, oil and gas is separated by the separating piston so that the damper can be installed in any position without having an idle stroke.

     

    Characteristics

    • With extension force F1
    • With idle stroke
    • Positionally independent 

     

    Application Examples

    • Waste containers
    • Overrun brakes
    • Industrial applications
    • Commercial vehicle interior
    • Seats for commercial vehicles
  • Dampers with bottom valve (BV)

    With this type of damper, the bottom valve separates the oil from the compensation chamber. The damper has no extension force and has to be installed with the piston rod facing down.

     

    Characteristics

    • Without extension force F1
    • Without idle stroke
    • Positionally dependent  

     

    Application Examples

    • Shop counter
    • Commercial vehicle interior
    • Engine vibration damper
    • Belt tensioner 
    • Seats for commercial vehicles
  • Dampers with bottom valve and membrane (BVM)

    The membrane in the compensation chamber behind the bottom valve expands when loaded (pressure) or contracts (tension). The damper thus works without extension force in any installation position.

     

    Characteristics

    • without extension force F1
    • without idle stroke
    • Positionally independent (installation of the piston in any position) 

     

    Application Examples

    • Overrun brakes
    • Commercial vehicle seats
    • Belt tensioner
    • Universally applicable
  • 2-tube damper

    The 2-tube dampers consist of an inner and outer tube, whereby the inner tube forms the working space. The space between the two tubes accommodates the oil displaced by the retracting piston rod. The damping force spring of the 2-tube dampers can be variably adjusted due to the internal structure. The weight is also reduced to a minimum due to the use of an aluminum outer tube.


    Characteristics

    • Model HD34: Ø Outer tube 34 mm oval (not adjustable)
    • Model HD38: Ø Outer tube 38 mm round (adjustable)
    • Ø Piston rod 10 mm
    • Damping force max. 6,000 N
    • Without extension force F1
    • Without idle stroke
    • Positionally dependent (installation of the piston rod on top)

     

    Application Examples

    • Commercial vehicle seats (vertical damping)
