    • lockable gas springs
    • Lockable gas springs

    • Controlled pushing, lifting and adjusting up to absolutely rigid locking in both directions.

      When considerable forces influence moveable construction parts, the reliable locking is important. The piston rod of the lockable easylift gas spring can be adjusted in every required position of the whole stroke by actuating the release pin. Depending on the occuring forces in your application, we can fit your lockable easylift gas spring for different load limits in a reasonable way. In this production program, the absolutely rigid locking easylift gas spring in both directions is a worldwide recognized innovation.

      The main use of the lockable gas springs of the easylift system is the independence of an external energy source, the comprehensive measures and the damped, controlled movement. Please see the 4 basic models and further function variations on our website. Or if you have the possibility you can see numerous function models in our facility. We assist you in the realisation of your projects.

      Of course, lockable easylift gas springs have the same positive characteristics – low friction forces and high reliability – as the other easylift gas spring types. You will receive the lockable easylift gas springs with the requested size and force within shortest time.

    • Lockable gas traction springs

    • Lockable gas traction springs are continuously adjustable over the whole stroke. The lockable gas traction spring can be released by pushing the release pin. When the piston valve opens, gas or oil can flow through the piston and the piston rod will be inserted. Due to the high reliability, this type of spring is preferentially used for medical equipment.

      Pull-in force: 100-4000 N (depends on diameter piston rod/cylinder
      Locking force in push and pull direction max. 10.000 N

    • Stainless steel gas springs

    • Gas springs are available with a lot of different lengths, forces and variants. They are also available in highly corrosion-resisting material.

      We mostly use high-quality stainless steel material, e. g. 1.4404 (V4A i.e. AISI-no. 316L) for the production of the stainless steel gas springs. They are not only resistant to water but are commonly found in the food, chemical and salt water applications. Please note the stainless class of the available connecting parts. All gas springs of these high-quality product groups are made with valve, with the exception of P-models and traction springs with damping.
    • MC Damper (Motion Control)

    • MC-Damper are used as safety and function elements in order to damp speed and to slow down masses.

      MC-dampers (motion control) is the generic term for special, delaying (damping) easylift products which can be used for many different safety and operating functions.

      Easylift MC-dampers slow down masses or damp speed according to the model. (They are not shock-, impact absorbers, or limit stop dampers.)
    • Connecting parts

    • The reasonable variety of the easylift connecting parts knows only one measure... your daily experience!

      For a detailed and controlled force development, you also need connecting parts which guarantee movement and force transfer in an ideal way. The comprehensive easylift range of hinge eyes, clevises, elbow joints, ball joints and metal fittings will fit nearly every mounting requirement.

      Regarding connecting parts, there will, of course, be new requirements from time to time for our easylift system. If the prospective application can be solved with easylift gas springs, we will also solve the problems regarding the connecting parts.

      Please note that the length of gas springs will change depending on your choice of different connecting parts. The length of the easylift gas springs is calculated as follows:

      From mid boring to mid boring for hinge eyes, clevises and hinge heads
      From mid ball to mid ball for elbow joints
      Without connectors the thread length is not included
  • Easymotion

  • Function of easymotion
    An alternative to the linear adjustment with Bansbach gas springs is our linear hydraulic actuation system which controls multiple adjustment cylinders synchronously. This is achieved by simultaneously controlling each cylinder. If light or heavy, the easymotion can be fitted on any application and can be customised to fit your individual needs - even if on multiple legs. Numerous Bansbach gas spring components are used in the production of the easymotion, which guarantees our well known high quality.

    easymotion components
    The easymotion system consists of a hydraulic pump, adjustment cylinders and the tubes for connecting each component. The system can be operated using an electric motor or manual crank.

  • Gas spring "Click & Go"

  • Only one push on the release button...

    The new Click & Go gas spring is a very comfortable alternative for all applications where the lockable gas spring shall always be pushed out completely after the release process. Due to the new Click & Go gas spring, this is possible with a single short push on the button. A permanent release over the whole stroke of the gas spring isn't necessary anymore. After a single release, the gas spring remains in
    released position.

    This gas spring type can, of course, be released by a hydraulic release system as well as by bowden wire. For further information about release systems and its respective connecting parts, please see our latest Bansbach-catalogue.
