Are the right locking gas spring with release button parameters important? They directly affect whether your equipment runs normally. As a Locking Gas Spring manufacturer, GASTAC provides measurement, calculation, and installation procedures in this guide, so you can find and get the right Locking Gas Spring with Release Button type, parameters, and installation.
Send us your load weight, mounting points, and required stroke. Our engineering team will confirm the right parameters and send a factory-direct quotation. Free technical consultation, no minimum order for samples.
Measurement — Confirm These Before You Order
Choosing the right Locking Gas Spring with Release Button starts with confirming the parameters. If you have the original part, measure it directly.
The center-to-center distance decides whether the strut mounts at all. The stroke decides the movement range — on an overbed table, stroke is the tabletop travel from lowest to highest. The end fitting type decides whether it connects to the existing bracket. For the full procedure, follow How to measure my gas strut?
Stroke and extended length are calculated together, not measured separately. If you only know the installation position, you can still work out the required stroke — see How to Calculate Gas Strut Length?
Mounting position decides whether the locking function works. A strut mounted beyond the specified angle may fail to lock or wear prematurely. For the standard procedure, see How to Determine the Gas Spring Mounting Position.
Calculation — Force Is Calculated, Not Guessed
Force depends on load weight, mounting geometry, and a safety factor. Too low and the lid will not hold. Too high and the user cannot push it down.
The mounting geometry — the distances from the hinge to the strut and to the load center — sets the required force. For how these distances are determined, see How to Determine the Gas Spring Mounting Position.
The full formula and worked examples are in The Gas strut force calculator. Stroke and length can also be calculated from the geometry rather than measured — see How to Calculate Gas Strut Length?
Installation — A Correct Strut Can Still Be Installed Wrong
Direction, angle, and cable routing decide whether the strut works after installation. Even a correctly sized strut can fail if it is installed rod-up or beyond the specified angle.
Rod-down keeps the oil seal lubricated. For the full step-by-step procedure, follow Installing a gas strut is essential for smooth, controlled motion.
Mounting angle must stay within the specified limit — beyond it, the strut may bind or leak. See What you must know about the Gas Strut Mounting Orientations.
Never modify the end fitting to force a fit. If the original bracket does not match, choose a different end fitting option. See If you already have a gas spring, follow the instructions below.
For release-button models, the cable needs a smooth path from the button to the valve. Sharp bends make the release stick. See Installing a gas strut on a lid transforms the experience.
Replacement — Match the Original, Do Not Approximate
A replacement must match force, stroke, end fittings, and locking type. Similar dimensions with the wrong locking type will not perform the same function.
Measure the old strut or note the part number before ordering. For the replacement process, see Introduction-replacing liftgate struts.
Worn struts lose force gradually, so the failure is often not obvious. Signs include difficulty lifting, the lid not staying up, oil residue on the rod, and noise during operation. For symptoms and diagnosis, see Over time, car hood or rear hatch gas struts components wear out.
