Construction of a Gas Strut Infographic
Our made-to-order gas struts and dampers provide engineered motion control solutions for a range of applications – solving complex product issues that can turn cloudy visions into reality.
Product designers often know that they need a gas strut to support and move their product or application, but not everyone knows and understands exactly what goes into making a gas strut in order to achieve the desired outcome.
We’ve put together this useful infographic and supporting content to break down how a gas strut is constructed and provide a quick overview of what its constituent parts do when applied to an application.
Gas struts are used for the lowering of weights as well as the lifting, damping and general safe manoeuvring of applications. Our range of gas struts have been used across sectors including aerospace, military, signage, medical, specialty vehicles and rail.
A gas strut is the same as a mechanical coil spring in so far as it’s a device for storing energy. However, where a coil spring’s energy comes from straining the material that makes up the spring, a gas spring’s energy comes from compressing the Nitrogen gas contained within it.
Gas struts are closed systems that are charged with inert Nitrogen gas and require no external energy source in order to operate. The pressure on either side of the piston remains equal irrespective of its position, which differs to a hydraulic or pneumatic cylinder that requires a pressure differential across the piston in order to move.
So, if this is the case, how does it work when no further gas is introduced, and the internal pressure remains equal? The answer lies in the small cross-sectional area of the rod where the gas is unable to exert any pressure. It is the difference between the gas pressure acting on the internal cross-sectional area of the rod, and the atmospheric pressure acting on the external end side of the rod that causes the rod to extend.
As the rod is pushed into the tube the available gas volume is reduced and the gas contained in the spring is compressed. This increases the pressure (or resistance to force applied) and this compression of gas creates the spring-like behaviour. A small path through the piston enables the gas to flow across the piston and also provides the means of controlling the speed of the spring as it is depressed and extended.
The strut is sealed with the end plug, preventing the gas from escaping and providing the attachment point for the end fitting.

How do gas struts work?
At Camloc Motion Control, we design and manufacture a wide range of engineered gas springs, struts and damper solutions to fit your requirements. Whether your project involves, for example, the door of a specialist vehicle or the hidden mechanisms of an operating table, our solutions will help you achieve the range of motion your application requires to work properly.
How to get the most out of your gas strut
At Camloc Motion Control, we’re proud to produce high-quality gas struts and dampers that contribute to manufacturing success in a variety of industries, from medical to aerospace. However, as a manufacturer, we’re heavily investing in the durability, strength and manoeuvrability of our products when they’ve left our factories, which is why we want to share how you can get the most out of your gas struts, improve their lifespan and quickly identify any warning signs that need attention.
How you choose the right gas strut for you and your product
At Camloc Motion Control, we understand that for every kind of project, there is a gas strut that can help you to lift, lower and control. However, there are so many different kinds to choose from. How do you know which type of gas strut you need? If you’re confused by which of our products is right for you, this blog post will help to guide your selection, if you’re still unsure you can visit our products page for each one, or alternatively contact one of our experts.
