Why choose our gas springs?
Our standard gas springs are charged with the exact amount of gas during manufacturing so that they deliver the right force in every application, for safe, reliable and long lasting operation. Their main benefits are:
- Constant opening force along the whole stroke.
- Automatic opening and comfortable closing with a light push.
- Hydraulic damping on the automotive models, which prevents knocks at the end of the opening.
- Interchangeable threaded end fittings for greater versatility.
- A wide range of sizes, forces and accessories.
- Springs built to the needs of each project.
How does a gas spring work?
A gas spring works from the internal pressure of the gas held in the cylinder. The compressed nitrogen presses on the piston and the rod, which generates a continuous extension force.
The force of the spring depends on the amount of gas introduced during manufacturing. Since the behaviour of the gas varies slightly with temperature, the springs are designed to keep a stable performance across a wide range of working conditions.
During movement, the hydraulic oil fitted to certain models provides progressive damping, which reduces impacts and extends the service life of the assembly.
Technical characteristics
Every standard gas spring is made up of:
- A high strength steel cylinder.
- A precision ground rod.
- A guide and sealing system.
- A nitrogen charge set during manufacturing.
- Threads for interchangeable end fittings.
The most common sizes include:
- Diameters from 6/15 mm up to 14/28 mm
- Lengths matched to each application
- Forces from 50 N to over 2,200 N
- A wide variety of end fittings and brackets

Applications of the standard gas spring
Gas springs are used across many sectors thanks to how reliable and easy to install they are.
Furniture
They are ideal for:
- Wall beds and storage bed bases
- Kitchen furniture
- Chest lids
- Hatches
- Office furniture
- Industrial furniture and equipment
When a lid has to lift a heavy load, the spring offsets the weight and makes opening easier.
Automotive
In the car industry, gas springs are used to lift:
- Boots
- Bonnets
- Tailgates
- Compartments on special vehicles
They also carry damping systems similar to small hydraulic dampers, which prevent violent closing.
Machinery and industry
They are also found in:
- Industrial machinery
- Technical cabins
- Production equipment
- Maintenance covers
- Machine guards
- A range of industrial applications
Other applications
Our springs are also suitable for:
- Skylights
- Marine hatches
- Refrigerated display cabinets
- Medical equipment
- Electronic equipment
Advantages of a standard gas spring
Choosing a standard gas spring brings a number of advantages:
- Fully automated opening.
- Completely self-contained operation.
- Simple installation with two fixing points.
- Lower cost than other lifting systems.
- Less maintenance.
- Wide availability of sizes and forces.
- Longer service life thanks to the quality of its components.
By offsetting the weight of the lid or the moving part, the user needs less effort and the installation is safer to use.
Fully customised configuration
We hold a very wide range of configurations so we can fit any project.
We can build a spring with:
- A custom length
- A force in Newtons to match
- Specific threads
- Compatible end fittings
- Different finishes
We also carry stainless steel models for applications exposed to damp, marine environments or corrosive conditions.
Compatible end fittings and accessories
Our wide range of accessories lets you install the spring in practically any application.
Eyelet end fittings
They carry a 6, 8 or 10 mm through hole for fixing with a screw or a bolt, and come in different thicknesses to suit each assembly.
Cup end fittings
They use a 10 or 13 mm ball socket that clips onto a ball stud bracket, which allows smooth movement and quick installation.
Brackets
We supply:
- Industrial brackets
- Cabinet brackets
- Ball stud brackets
- Steel and stainless steel versions
Solutions matched to each project
Every application calls for different behaviour. That is why we configure each gas spring around:
- The length needed
- The force of the spring
- The space available
- The weight it has to offset
- The working conditions
- The specific needs of the customer
Our aim is always to offer the most efficient solution for any sector, whether industrial, automotive or furniture.

Frequently asked questions
What is a gas spring?
A gas spring is a sealed mechanical actuator that uses pressurised nitrogen to make it easier to open, close and hold lids, doors and other moving parts.
How does a gas spring work?
The compressed gas inside generates a constant force that helps lift or hold a load smoothly and under control.
What is the difference between a standard gas spring and a locking one?
The standard spring moves continuously and cannot be fixed at intermediate positions. The locking model can be stopped and held at any point of the stroke.
How do I choose the right force?
The force depends on the weight of the load, the mounting position and the opening angle. It is expressed in Newtons (N) and has to be calculated for each application.
What details do I need to replace a gas spring?
You need the length, the stroke, the force in Newtons and the type of end fitting to find a compatible model.
Can a gas spring be made to measure?
Yes. We can build springs with the length, force and end fittings that best suit each application.
What are gas springs used for?
They are used in boots, bonnets, wall beds, kitchen furniture, industrial machinery, skylights, refrigerated display cabinets and many other applications.
Do gas springs need maintenance?
No. They are sealed systems that need no maintenance or lubrication during their service life.
How long does a gas spring last?
Its life depends on the use and the working conditions, although a quality spring is designed to withstand thousands of opening and closing cycles.
Can the end fittings be changed?
Yes. Our springs have threaded end fittings that can be swapped for others compatible with the installation.
Are there stainless steel gas springs?
Yes. We carry stainless steel models for damp or marine environments and for anywhere there is a risk of corrosion.
How do I know when to replace a gas spring?
If the lid no longer stays open, loses force or the movement stops being smooth, it is time to replace the spring.
