Adjustable Force Gas Strut – VARI‐LIFT

Our adjustable force gas strut- Vari-Lift can be set to meet your exact requirements in a wide range of situations. The key benefit of this type of gas strut is that the force adjustments can be made with the gas strut fitted to the application, saving you both time and effort.

What does the adjustable force gas strut do? 

If you require a gas strut but need it to be adaptable enough to respond to an unusual load or be set to a personal preference, then this is the product to consider. This product works in all the situations and for all the applications that our standard gas struts can be used for. However, this product enables customisation that is easily achievable there and then. 

 Adjustable gas springs can be used during product prototyping to attain the required force for fixed-force production gas springs. They can also be used where the weight of your products varies between models and can be degassed to provide the perfect action for your needs. 

Fixed Force Compression Gas Struts – Swift and Sure
A self-contained standard gas strut solution for lifting, supporting and counterbalancing
Fixed Force Stainless Steel Compression Gas Struts
The ideal gas strut for use in harsh environments and where high levels of cleanliness are required
Multi-Positional Gas Struts – Stop & Stay / Stop & Stay+
The gas strut that enables precise, multi-position positioning over the entire stroke
Locking Gas Struts – Blocklift (Type BL1 and BL3 only)
A gas strut that uses a special internal locking valve to allow the strut to be stopped in any position
Safety Locking Gas Strut with Shroud – Econoloc
Used where safety is of paramount importance, the strut cannot be compressed unless unlocked

What are the key benefits of the adjustable force gas struts? 

  • Adjustable to any force within range 
  • Force can be easily adjusted after installation 
  • Simple adjustment using standard tool supplied 
  • Ideal for prototyping and short production runs 
  • Available as an option on most types of Camloc gas springs 
  • Ideal where application weights vary 
  • Available in stainless steel 


How do the adjustable force gas struts work? 

All standard, shrouded, multi-positional and stainless-steel gas struts are available in a VARI‐LIFT version which can be adjusted to meet individual preferences as well as being adjusted in‐situ. 

The gas struts are charged to their maximum force during the manufacturing process and using the tool provided, gas can be gradually released via the VARI‐LIFT valve at the end of the tube to provide the force suited to your application. Once the correct force has been established,  we can measure this level of pressure and provide production fixed force gas springs that are all pre-set to your precise requirements.  

Although theoretical forces can be calculated with good accuracy, what can’t be calculated are factors such as hinge friction and the customer’s perceived speed of action. This is where the Vari-Lift option comes in.
