In the world of motion control, few components work as quietly—or as effectively—as the gas strut. From heavy industrial hatches to compact cabinetry and vehicle panels, gas struts provide the lifting, dampening, and stability we often take for granted. But getting the right one isn’t always as simple as grabbing the closest replacement. It’s about size, pressure, function—and getting it right can make all the difference.
This blog breaks down the basics of choosing the ideal gas strut, including the variables that matter and where to turn when precision counts.
Understand the Role
Gas struts are used to ease the lifting and controlled lowering of heavy or awkwardly positioned objects. They consist of a pressurised cylinder with a piston rod that provides consistent force across its range of motion. When operating correctly, struts offer smooth and stable support, keeping things open when they should stay open, and letting them close safely and quietly.
Know Your Requirements
Every strut is designed with specific technical parameters. To make sure you select the right replacement or new application, consider:
- Extended length: The measurement from one mounting point to the other when fully open.
- Stroke length: How far the piston travels between extended and compressed states.
- Force rating (Newtons): Dictates the amount of lift—too much and it’s hard to close, too little and it won’t stay up.
- End fittings: Ball sockets, clevis forks, brackets, and eyelets are among the common types.
- Mounting position and orientation: Depending on the environment, some struts must be installed rod-down to ensure lubrication and longevity.
Applications Beyond the Obvious
Gas struts are ubiquitous in automotive and industrial settings, but their use doesn’t stop there. You’ll also find them in:
- Overhead kitchen cabinets
- Medical and dental equipment
- Camper trailer lids
- Marine hatches
- Caravan doors and pop tops
- Toolboxes and utility compartments
Each application presents its own challenges—whether it’s exposure to weather, angle of deployment, or frequency of use.
When Standard Won’t Do
Even with a large catalogue of off-the-shelf products, sometimes the standard dimensions or pressure won’t suit. That’s where trusted suppliers like Schutts Industrial come in. Their team has decades of experience matching gas struts to the demands of specific equipment and machinery—and when needed, they offer made-to-order struts tailored to your exact requirements.
Better still, their support goes beyond shipping a box. They assist with fittings, installation advice, and adjustments—so you’re not left guessing.
Fixed vs. Adjustable
Standard gas struts are pressurised to a set value at the factory. This works perfectly if the load and geometry are known—but not so much for prototypes or systems with variable weight.
Adjustable gas struts provide flexibility: gas pressure can be gradually reduced through a release valve until the optimal force is achieved. Once set, they perform just like fixed-force versions. It’s a smart option for builders, engineers, and anyone refining a new design.
Caring for Your Investment
Gas struts are built to last, but like any mechanical part, they thrive with proper treatment. Here are a few pro tips:
- Always mount with the rod facing down to maintain internal lubrication.
- Avoid side loading by keeping the strut aligned during motion.
- Don’t lubricate the piston rod—it’s already coated and self-lubricating.
- Replace in pairs for balanced performance and load distribution.
- Protect in harsh environments using boots or covers, especially in coastal or industrial settings.
Wrapping Up
Whatever your project—from a busted tailgate to a custom bench seat—choosing the right car bonnet gas strut or general-purpose gas spring comes down to details. Take the time to measure, match, and consider how your component will be used. And if you need backup, Schutts Industrial is right there with advice, inventory, and fast fulfillment to get you moving again—no guesswork needed.
