In general the length to choose for gas struts is about 55% of the height of the door you are trying to keep open. So if you have a door that is 1000mm in height a 550mm 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.
What can I use instead of gas struts?
A mechanical stainless steel strut called the mStrut has been developed by Associated Spring as a reliable alternative to gas struts, which are widely used to ease the effort of lifting or lowering interior hinged bulkheads.
How do gas struts work on bed?
Bed struts
The reason why a pull down bed can be easily folded and unfolded is due to the use of gas struts. Without a gas strut, folding the bed in and out would be much heavier. The gas strut provides a springy effect, which dampens the movement.
How do you calculate gas strut strength?
Introducing Gas Struts to something.
When adding struts for the first time you need to follow our Gas Strut Selection Formula:
- Calculate half the dimension of what you are lifting (H),
- Weight of what you are lifting (G),
- Mounting distance from the hinge (L)
- What size struts you require.
What size gas struts do I need? – Related Questions
Do gas struts have to be fully extended?
Extended length: You need the length of the gas strut when it’s fully open or extended.
Do gas struts push or pull?
The pull type gas springs operate according to the converse functional principle as the push type gas springs. That means the gas pressure in the cylinder pulls the piston rod inside. Application examples are flaps, windows and hatches that mostly open downwards.

What does 100N mean on gas struts?
European gas springs have the letter ‘N’ for Newton. The Newton value can easily be used to estimate the kilogram force: 1 kg is equivalent to approximately 10N. For example, if your hatch weighs 10 kg, you will need a 100N gas spring.
How do you calculate gas strut length and force required?
The length of the gas strut should be around 60% of the length of the lid, hatch or door. The position of the gas strut is determined by the length of the lid. The gas strut should be placed on the lid on 20% of the length. By following those guidelines, you will be able to close the lid, hatch or door in a proper way.
What do the numbers mean on a gas strut?
On the body of the Stabilus gas strut you will find the part number (product code) usually a 6 Character code and can be followed with a series of other digits. which denote the Force (N), the manufacturing batch and may also denote the End fitting type in some cases.
How are gas strut mounts measured?
How to measure Gas Struts
- Step 1 – Extended Length. Measure the gas strut from middle of end fitting to the middle of the end fitting when gas strut is fully extended.
- Step 2 – Diameter. Measure across the Rod/Shaft.
- Step 3 – Newton Meters or Force. There are few ways to work out the Newton Meters (Nm).
- Step 4 – End Fittings.
How long do gas struts last?
That depends. “Driving on rough or unpaved roads, towing a trailer or carrying heavy loads, can shorten their functional life,” says Reina. “With heavy use, you could be looking to replace them at 40,000 or 50,000 miles or sooner. Under normal conditions, 75,000 to 90,000 miles might be reasonable.”
Why do gas struts fail?
Most failures are due to a gradual loss of pressure to the gas which results in the strut being unable to support the load. The risks are that the component being supported will gradually creep down or drop without warning.
What angle do you install gas struts?
This will normally be around 10° to 30° from fully closed. In practice, this will vary by several degrees between opening and closing, due to factors such as friction of the internal components of the spring, hinges and end connectors.
Can you adjust pressure on gas struts?
The internal pressure of a gas strut is very high and should be treated with caution. Using the Allen key provided undo the grub screw until gas can be heard escaping. Then re-tighten the grub screw. Only release the gas in one second bursts to avoid releasing too much gas.
Can gas struts be used vertically?
Gas struts should be mounted at an angle of 60° to the vertical with the piston rod down to ensure lubrication of the cylinder seals.
Can gas struts work vertically?
Photo: A vertically mounted gas spring supports the seat of this “gas-lift” office chair, making it easy to adjust the height. Gas springs generally work best in a vertical position like this. There’s less chance of them buckling when fully extended and the oil inside lubricates them more smoothly and evenly.
How long do gas springs last?
A gas spring can usually be operated around 40,000 times. In other words, its lifespan depends on how many times it is opened and closed. A gas spring for a kitchen cupboard will usually remain functional for around 3–5 years.
Why won’t my gas struts compress?
If your gas strut will not compress you need to let more gas out of it. The pressure is too high for the strut to compress under the weight of the door. If all the gas has been released out of the strut and it still won’t compress it is likely that your struts have been overextended.
Where do you mount a gas strut?
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.
Can a gas strut explode?
Compressed gas struts where the gas and fluid inside the strut becomes overheated during a vehicle fire can result in an explosion of the strut assembly, launching a projectile that can cause serious injury to first responders.
