How do gas struts work?

13 February 2023 How do gas struts work?

Everything you need to know about the gas strut

Have you ever wondered how gas struts work and why they are used in so many different places? Gas struts are essential equipment with wide applications in numerous industries, from transport to construction. They can be used to lift heavy objects, such as lids or doors, or provide safety around homes and public spaces. In today's blog post, we'll explore the fascinating world of gas struts and how they work to gain an appreciation for these under-the-radar mechanisms.

Firstly, what are gas struts?

Gas struts, sometimes referred to as gas springs, are a special type of spring that relies on pressurised gas inside a tubular structure to apply excessive force. Most commonly found in automotive applications such as tailgates and bonnets, these components are used for space-saving furniture pieces, medical equipment, toolboxes, and many other mechanical systems. 

Manufactured from high-grade steel and containing a nitrogen-charged outer tube with an internal piston rod assembly, compressed gas struts offer a smooth resistance profile. By combining durable materials with specialised technology and precise engineering, these lightweight mechanisms deliver consistent performance while allowing gas pressure differential levels with easy installation.

How gas struts operate

Gas struts are components commonly used to hold heavy objects such as doors, lids and hoods. They are a type of spring that uses pressurised gas to generate external force and provide the required support. Here is how they operate:

  1. Gas struts consist of a metal rod with rubber ends containing pressurised gas inside.
  2. As these mechanical springs are stretched or compressed, the internal pressure from the gas increases or decreases respectively due to the movement of the metal rod. This change in high pressure creates a force used for support and stability.
  3. The force generated by gas struts only changes over time if there is an increase or decrease in the pressure of the gas inside the rod. This means they can be relied on for long-term support in various applications.
  4. Replacing gas struts can be tricky, so seek professional help!

The different types of gas struts

There are several different types of gas struts available in the market. When choosing a gas strut for your application, it is important to consider the type most suitable for the particular task. 

Depending on your needs, you can choose from single-acting or double-acting gas struts, which differ in the directionality of their force generation; and preset gas struts, which offer greater flexibility; heavy-duty and lightweight gas struts designed for heavier and lighter applications, respectively; and locking and non-locking gas struts that offer added security when needed. With a wide variety of options, finding the right gas strut has never been easier!

Vehicle gas struts

Vehicle gas struts, also known as automotive gas struts are responsible for holding hoods and trunks open while they are being accessed, providing much-needed convenience and safety. 

Dampner struts

Dampner struts are a type of gas strut designed specifically for dampening mechanical vibrations. These dampers provide improved stability for machinery by absorbing shocks and preventing oscillations from occurring in the system. 

Dampner struts have been used in many applications, from industrial machines to lab equipment, providing smooth and dependable operation while minimising noise generated by the systems they support. Additionally, they benefit from a long service life and can be used in virtually any environment. 

Industrial application gas struts

Industrial applications gas struts are designed to provide additional support for industrial settings, allowing machines and systems to handle heavy loads while minimising vibration and noise. 

Gas struts in industrial applications may be used to keep safety doors open or closed when needed or easily lift heavy machinery parts into place. In many cases, these struts' higher temperature range and pressure load capacity make them ideal for use in an industrial setting. Furthermore, they have a long service life due to their robust construction and can be easily replaced if necessary without too much downtime.

Heavy-duty replacement gas struts

Heavy-duty replacement gas struts are a great option for replacing worn or damaged factory-installed gas struts on machinery and industrial components. These heavy-duty replacement struts offer superior performance in terms of pressure load capacity, operating temperature range and reliability, ensuring that your equipment operates smoothly for years to come.

Frequently asked questions about gas springs and struts

Are gas struts and gas springs the same thing?

Although both use compressed nitrogen gas for power, there are distinct differences between these two pieces of equipment. Gas struts provide rigid support, while gas springs work to primarily offer smooth motional control capabilities. In summary, although both types of equipment are powered by nitrogen gas, each has its own unique capability and purpose.
