Gas Spring

Gas Springs, Gas Struts Components

Gas Spring
  • A.
    Tube Side Connection Part

    Connecting part available in many variations. For detailed information please check our Mounting Catalogue.

  • B.
    Pressure Tube

    Gas Spring tubes are seamles and bodies are treated with a highly corrosion-resistant coating.

  • C.
    Nitrogen (N)

    Gas springs are filled with pure nitrogen. Nitrogen is an inert gas, wich does not burn, will not explode and is not poisonous.

  • D.

    Each Tunalift Gas spring is manufactured with a specific quantity of oil, which serves both as lubricant and damping medium.

  • E.
    Piston Package

    The axially movable piston ring acts as a control element.

  • F.
    Seal and Guide Element

    The seal that prevents the pressurized gas from escaping and ensures the highest level of functional safety.

  • G.
    Piston Rod

    Induction Hardened and 3 times stoned Chrome Plated Rod for durable life time. Nitrated rod is also possible as an alternative.

  • H.
    Rod Side Connection Part

    Connecting part available in many variations. For detailed information please check our Mounting Catalogue.

Pressure Behaviours

Gas Spring Force Changes, Tolerances

Nitrogen (N) is an inert gas and and a common element in the universe which is being used in gas springs for force supply. However, Nitrogen has flexible character due to temprature changes which also affects pressurre rate of gas spring. This phenomenon is visible in (fig. a). Optimum working temprature for gas springs is 20c, yet, it is operational between -20C to 80C. Besides temprature, gas filling process also has tolerance rates because of filling pressure bar, internal tube volume, accuracy of valves and etc. These tolerance rates changes according to determined F1 value. Please check force tolerance table (fig.b) to see plus and minus tolerances of your gas spring. We test pressures of each gas springs in production stage, also after production proccess we make most accurate tests periodically to determine possible inaccuracies (fig.c).
