Gas springs, or gas struts, are rods that provide support for doors, hatches, lids and covers that are horizontally hinged. They act as support in a variety of ways including, lifting, positioning and lowering; because of this versatility they are used in a wide range of applications.
What can gas struts be used for?
Gas struts are used in many ways to give mechanical assistance to lifting and supporting components such as tool box lids, car bonnets, boot lids, rear doors and camping trailer hatches. Office chairs are another common use of a similar but different form of gas strut.
Is gas spring better?
Coil springs are used primarily because they are more economical, and have no parts to fail or seals to leak so they also have extreme longevity.
| Coil Springs | Gas Cylinders |
|---|---|
| Not as smooth or quiet in operation | Smooth, silent operation |
| Faster “kick back” (stronger release force) | Slower “kick back” |
Are gas springs reliable?
What is a Gas Spring? Gas springs are a proven and reliable method of counterbalancing large covers and objects. They offer ideal capabilities for safely lifting, lowering and positioning heavy or cumbersome objects.
How do gas strut positions work?
In general, the length to choose for gas struts is about 55% of the height of the Hatch you are trying to keep open. So if you have a door that is 1000 MM in height a 550 MM long gas strut would be about right. In simple terms, we are talking half the door height plus a bit when determining optimal gas strut length.
How long do gas springs last?
Gas springs normally lose their pressure gradually over a period of 2-7 years depending on operating conditions.
Do gas struts need springs?
Mainly used in vehicle suspension, gas struts contain a coil spring which supports the weight of the vehicle and a shock absorber that absorbs and dampens shocks and vibrations.
Do gas springs push or pull?
Gas pressure internal to the strut provides a push or pull force depending on configuration, but also contains a dampening circuit typically to control the speed of motion through one or both directions of travel. Gas struts are often referred to as Gas springs, gas pistons, gas shocks, among other names.
Is a gas spring a damper?
Fully damped gas springs can be described as damper units filled with nitrogen gas at high pressure (Figure 4). These units provide an even control through their stroke and can be used at any orientation.
What are the different types of gas springs?

Why do gas springs fail?
The dirt collects on the piston rod whilst it is extended so that, when compressed, it mixes with the gas and oil. This causes progressive damage to the chamber seal, eventually causing the spring to fail.
How do I choose a gas spring?
Follow these steps to calculate a gas spring:
- Decide what you want to use the gas spring for.
- Enter the dimensions of the application.
- Measure the thickness of the application.
- Investigate which material the application is made of.
- Determine the total weight of the application.
- Determine the position of the pivot point.
How does a gas lift work?
Gas lift is a method of artificial lift that uses an external source of high-pressure gas for supplementing formation gas to lift the well fluids. The principle of gas lift is that gas injected into the tubing reduces the density of the fluids in the tubing, and the bubbles have a “scrubbing” action on the liquids.
What is a locking gas spring?
The locking gas springs, also called gas pressure springs, gas dampers or gas pressure dampers, aid the ergonomics and comfort for conveniently safely changing seated and lying positions, for effortlessly and precisely operating machine covers and are used in many other applications.
How does a lockable gas spring work?
The fascinating feature of a lockable gas spring is that its rod can be locked at any point in its travel – and remain there indefinitely. The tool that activates this mechanism is a plunger.When the plunger is released – and this can occur at any point in the stroke – the rod is locked in a specific position.
Where should gas struts be placed?
When installing a gas strut it should be on a sixty degrees or less tilt with the cylinder the highest point not the shaft. This is because the Gas Strut cylinder houses a small amount of oil in charge of keeping the seal lubricated and oiling the shaft as it passes through the seal.
What does N mean in gas struts?
It stands for Newton Meters and is a measurement of pressure. It essentially makes your gas strut work. Look for a N or Nm after a number on you Gas Strut…see below.
Are all gas struts adjustable?
Can I adjust the force of a gas strut? Yes, all our gas struts are adjustable gas struts.
Can you repair gas springs?
Gas springs are self-contained units that require no periodic maintenance or service beyond being kept clean and dry. Lubrication of the spring is internal and no external lubrication is required. Repair of gas springs is not possible as loss of force is caused by main seal damage and gas springs should be replaced.
Do springs wear out?
Springs typically last a long time and, in some cases, can even last the lifetime of the vehicle. However, that doesn’t mean springs don’t wear and become worn out over time. When springs do reach the end of their lifespan because they’ve lost their resilience or have become broken, ride quality and safety suffer.
When were gas springs invented?
1891
The first gas springs were patented in 1891 by Paul Giffard, a Parisian engineer. Giffard designed them for use in guns.
