What are gas springs and what are they used for?

Gas springs, also known as gas springs or gas pressure springs, are innovative technical solutions that are used in a wide range of applications. These springs consist of a cylindrical housing filled with gas under high pressure and a piston rod that moves freely within the housing. The gas pressure within the housing provides the critical ability to absorb and exert controlled forces to assist, create or block movement (lockable gas springs). Especially when it comes to simply lifting, lowering or holding a heavy load. This makes gas springs indispensable components in areas such as automotive, rail, furniture, commercial vehicles, industry, medicine and aviation. They enable the smooth opening and closing of doors, cabinets, flaps and hoods as well as the balancing of heavy loads, significantly improving the efficiency and safety of modern systems.

Standard gas spring 

This type of gas spring is most commonly used in a variety of applications, from furniture to cars to industrial machinery. They are available in different sizes and capacities and are usually easy to use and install. Once forces are applied to this type of spring, the compression of the gas inside allows for smooth and controlled movement. As soon as the external force is released, the compressed gas expands again and the gas spring returns to its original position. This type is ideal for applications where a constant, smooth movement is required, e.g. when opening, closing and sliding doors and flaps. A general distinction is made between the following options:

  • Gas spring without connections
  • Gas spring with welded connections
  • Gas spring with ball joints

Lockable gas spring

Lockable gas struts can be locked in any position and are divided into rigid and elastically lockable gas struts. Find out more under our menu item lockable gas struts.

Individual gas springs

In the diverse world of gas springs, there is not always a "one size fits all" that can be used for all applications. Instead, there are individual gas springs that are designed to meet the requirements and needs of the application. Both the spring force and the specific gas pressure are regulated in order to adapt the damping or support to the requirements. 
Individual springs also include the gas traction spring (tension spring), which expands or contracts when it is loaded. It generates a tensile force that is used to pull or stabilize objects. Gas tension springs are often used in applications where the object needs to be pulled or held in an extended position, such as in loading mechanisms of transport vehicles or in motorized gates.
Whether it's special dimensions, unique force specifications, special materials or unusual installation angles - let us advise you on individual gas struts. We ensure that you receive not just a gas spring, but a precise, reliable and durable solution. 
In addition, we offer a wide range of components such as connecting elements and release systems that allow you to tailor the various gas struts precisely to your specific application. With our product range, we are able to provide you with tailor-made solutions for every requirement and offer you the optimum quality standard and the desired control in your application.

Insights into the mechanics and mode of operation - How does a gas spring work?

Gasfeder_Schnittdarstellung

Structure of a gas spring

Gas springs are pneumatic adjustment elements and are often simply referred to as springs. Most gas springs are made of steel and are therefore extremely robust. As already described, they consist of a pressure tube and a piston rod including an associated piston packet. There are various connecting parts at both ends of the pressure tube and the piston rod, which enable smooth integration into your specific application.

At the heart of a gas spring is its sealing and guide system, which ensures excellent sealing of the interior - even under extreme environmental conditions. The spring is filled with non-toxic nitrogen under pressure. Different filling pressures inside the spring lead to individual extension forces. In the application, the piston rod extends when the extension force of the gas spring is greater than the (weight) force acting from the outside, while it contracts, i.e. retracts, when the extension force is lower. The speed of extension is tailored to your needs thanks to the adjustable damping system. 

In addition to nitrogen, the interior contains a fixed amount of oil for lubrication and end-position damping.

The basics of the gas spring mechanism

The operation of gas springs is based on an ingenious principle that precisely controls the movement of the piston rod. The gas pressure inside the cylindrical housing is regulated by the nitrogen filling process, which allows the extension force of the gas spring to be set to a predefined value that meets the specific requirements of the application. This piston rod extension movement is continuous, resulting in a controlled movement. In addition, internal overflow channels ensure that the movement is damped to prevent abrupt movements and ensure a smooth, controlled movement right up to the end stop. Overall, the design of our gas springs enables smooth and controlled movement.

Pressure Regulation during the Installation of the Gas Spring

Calibrated pressure gauges ensure precise control of the pressure inside the gas spring. These pressure gauges also allow adjusting the gas pressure to an optimal and predefined value tailored to the specific requirements of the application. Higher pressure results in stronger spring force, while lower pressure generates a weaker spring force.

Damping of Gas Springs

A crucial aspect of gas springs is damping. When the piston rod moves in the extension direction, nitrogen is directed through the piston. Its variably sized flow channels control the extension speed of the rod. The oil in the gas spring gently slows down the piston during extension. This process prevents abrupt movements and ensures a smooth, controlled speed until reaching the end position.

Different areas of application for gas springs

Gas springs are used in a wide variety of industries and sectors, where they fulfill different functions.

How is the correct extension force of a gas spring calculated?

The calculation of the correct pressure, and thus the extension force of gas springs, is a crucial step to ensure they function effectively and perfectly in the selected application. Generally, the required pressure depends on various external and internal factors. These factors include the weight of the load to be moved, the installation length, rotational angle, stroke, and the ambient temperature, among others.
It's also important to note that additional factors such as friction, contamination, vibrations, and speeds need to be taken into account. As experts, we are available to help you determine the appropriate extension force for your specific application and ensure the best possible performance of your gas springs.
