Adjustable Force Gas Strut

Introducing our innovative adjustable force gas strut - the Vari-Lift. With its remarkable flexibility, the Vari-Lift allows you to effortlessly adjust the force to perfectly meet your specific requirements across a multitude of situations. This outstanding gas strut stands out because it offers the convenience of making force adjustments while the strut is still fitted to your application, saving you valuable time and effort.

What does the adjustable force gas strut do? 

The adjustable force gas strut is a versatile solution designed for projects that require adaptability and precise adjustments. If you need a gas strut that can easily adapt, respond, and be customised to specific requirements, then the adjustable force gas strut is the perfect choice.

This product offers all the reliability and functionality of our standard gas struts, with the added benefit of being easily customisable. It excels in a wide range of situations and can be used in various applications just like our standard gas struts.

One of the key advantages of adjustable gas springs is their suitability for product prototyping. During this phase, having the ability to attain the required force is crucial. Adjustable gas springs provide the flexibility to fine-tune the force to meet your needs, allowing for a smooth transition to fixed-force production gas springs.

These gas springs are also ideal for scenarios where the weight of your products varies between models. With the option to degas the gas springs, you can ensure that the correct action is achieved precisely when it is needed.

What are the benefits of the adjustable force gas struts? 

  • They are adjustable to any force within range  
  • The force can be easily changed after installation  
  • They are simple to adjust using standard tool supplied  
  • It’s the ideal solution for prototyping and short production runs

How do the adjustable force gas struts operate? 

At Camloc, we offer a wide range of gas struts, including standard, shrouded, multi-positional, and stainless-steel variations, all available in our VARI-LIFT version. The VARI-LIFT gas struts can be easily adjusted to meet your individual preferences, providing unparalleled versatility for your applications.

During the manufacturing process, our gas struts are charged to their maximum force. However, with the VARI-LIFT version, you have the power to fine-tune the force to suit your specific needs. Using the tool provided, you can gradually release gas via the VARI-LIFT valve located at the end of the tube. This allows you to precisely adjust the force to match your application requirements.

Once you’ve established the correct force setting, we can measure the pressure level and provide production fixed-force gas springs that are pre-set to your precise specifications. This ensures consistency and eliminates the need for further adjustments, saving you time and effort.

While theoretical forces can be calculated accurately, certain factors like hinge friction and the customer’s perceived speed of action cannot be predicted. This is where the Vari-Lift option truly shines. It allows you to fine-tune the gas strut’s force to overcome any unforeseen variables and achieve the desired performance.

Trust in Camloc’s VARI-LIFT gas struts to offer exceptional adaptability and customisable force settings. Our commitment to providing reliable and high-quality gas spring solutions is matched by our dedication to making them accessible and understandable to anyone. Experience the convenience and precision of our VARI-LIFT gas struts and take control of your applications with confidence.
