How Do You Measure Gas Springs?

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.

How do I know what size gas struts 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. In simple terms we are talking half the door height plus a bit when determining optimal gas strut length.

How do you calculate gas spring placement?

The force required to hold the lid open (F1) can be calculated using the formula: Gas Spring Force (F1) = Mass of lid x Centre of Gravity / Radius of Force x Number of Springs. The calculations show that the closer towards the hinge the moving mounting point gets, the higher the opening force required.

How do you measure gas struts to replace?

Co-Mac’s gas strut length is measured from the centre of the ball joint at each end. If you want to replace an existing gas strut, measure the length of your strut from the centre of each ball joint. If your gas strut does not have ball joints, measure the length of the gas strut with no end attachments.

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.

How do you calculate gas strut pressure?

Next… The General Rules

1. The Extended Length of Gas Strut = 60% of the Length of the Lid. So say the lid is 1000mm you would need: 600mm long gas strut. Extended Length: 600mm.
2. The Position of the Gas Strut on Lid = 20% of the Length of the Lid. So the Lid is 1000mm you would position your Gas Strut: 200mm.

How are cabinet struts measured?

Measure out from the edge of the door on the hinge side 2 1/2 inches and make a 2-inch-long mark across the side of the door. Measure perpendicularly along the first mark and make a mark at 1 inch. The point where the lines intersect is the center point of the bracket that holds the strut to the door.

How are gas canopy struts measured?

How To Measure Gas Struts

1. Measure the Gas Strut when it is fully extended from the Centre of the End Fittings.
2. Measure the Diameter of both the Barrel and the Rod.
3. Measure the exposed Rod length from the Barrel to the centre of the End Fitting.

How do you test gas struts?

How to Measure

1. 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.
2. Step 2 – Diameter. Measure across the Rod/Shaft.
3. Step 3 – Newton Meters or Force.
4. Step 4 – End Fittings.
5. Step 5 – Order your Gas Strut.

Are all gas struts adjustable?

Can I adjust the force of a gas strut? Yes, all our gas struts are adjustable gas struts.

How do you read a stabilus number?

The number is listed in the red square and consists of six digits or 4 digits and 2 letters. The number to the right is the pressure (here: 900N).

How much pressure is in a gas strut?

Struts contain nitrogen gas under pressure and some oil to damp movement and to lubricate the seals. Operating pressures are typically in the range of 1700 to 15200 kPa (250 to 2 200 psi).

How do you unlock a gas spring?

To unlock, the support tube is swivelled back into the central position. The lock of a gas spring with the lock on the inside is comparable with the mechanics of a ball point pen. A light push on the piston rod in the extended position locks it; a quick movement in the extension direction releases the lock.

How do I select gas springs?

Follow these steps to calculate a gas spring:

1. Decide what you want to use the gas spring for.
2. Enter the dimensions of the application.
3. Measure the thickness of the application.
4. Investigate which material the application is made of.
5. Determine the total weight of the application.
6. Determine the position of the pivot point.

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.

How do you calculate travel shocks?

Raise the wheel to ~4” above ride height (measured vertically), record the exact compression. Measure and record the distance between the shock mounts. The amount the shock moved between droop and bump divided by the amount you moved the wheel is your motion ratio.

How do I know what size lift is on my truck?

Look at the front crossmembers for the lower control arms. Measure the distance from a lower control arm bolt to the factory control arm mounting hole above it. If your kit uses blocks in the rear instead of leaf springs, measure the size of the block. The rear of most kits will be 2-3 inches less lift than the front.

How do tension gas springs work?

Gas Tension Spring
These springs are built on a two-cylinder principle. The gas is only on one side of the piston. The gas is compressible. When enough external force is applied, the piston rod is pulled out of the cylinder and the gas spring compresses the gas in the outer cylinder.

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.

What angle should a gas strut be?

sixty degrees
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.
