How are gas strut positions determined?
How are gas strut positions determined?
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.
How are struts measured?
How To Measure Gas Struts
- Measure the Gas Strut when it is fully extended from the Centre of the End Fittings.
- Measure the Diameter of both the Barrel and the Rod.
- Measure the exposed Rod length from the Barrel to the centre of the End Fitting.
How are gas springs measured?
The first type of gas springs are springs with welded mesh at either end. With this type of springs, we measure the total length from the centre of one mesh to the middle of the second mesh. The second type of springs are terminated threads. Both types of gas springs are measured in a fully distended state.
Are gas struts measured open or closed?
The compressed length of a gas strut is when the gas strut is completely closed. Normally when the window or door is closed and can be measured pretty easily when a gas strut fails because it no longer has any Newton Meters (force) left in so the gas strut will be very easy to push closed.
What does N mean in gas struts?
Newton Meters
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.
Which way round do gas struts go?
Note: – Always install after painting, welding etc. – The gas strut should always be fitted with the piston pointing down. – Use suitable end fittings and angle joints to avoid coupling jamming.
Can gas springs be recharged?
There is no problem with refilling gas springs, but postage costs often mean it is not worth it, as a gas spring is not an expensive product. Variload gas springs are often used for testing and development.
What is a gas charged strut?
A: gas charged shock or strut uses high-pressure nitrogen gas to reduce oil foaming during high-speed damping, and therefore maintains performance. It is possible to do a quick check at home for wear on your vehicle’s shocks or struts.
How big of a gas strut do I Need?
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.
What should the crossover angle be for a gas strut?
As is seen in the figure below, at 20°C crossover occurs at an opening angle of around 7°, with the handling forces being acceptable in both opening and closing. Gas Spring and gas strut installation handling forces chart. Crossover at 20 degrees Celsius. Angle of opening (Degrees) vs. force (N).
How big is a gas spring strut lid?
Basics of sizing a gas spring Gas Spring Size Approximate Lid Weight 6-15 Up to 10kg 8-18/19 10-40kg 10-23 40-150kg 14-28 150-350kg
How can I tell if my gas strut is moving?
This type of mounting can be identified by the end at the lowest point of the strut when closed, rotates to the highest point when fully open. It can also be identified by the moving mounting point being located further away from the hinge than the fixed mounting point
