Traction gas springs
Traction gas springs, also known as pull-type gas springs, operate in the opposite way to compression springs. Instead of pushing outward, they pull inward. At rest, the rod remains inside the cylinder, and when extended, it generates a return force that ensures smooth and reliable retraction of hatches, lids, and panels.
At Lesjöfors, we design and manufacture traction gas springs for applications where controlled inward force is essential. Offering a wide range of stroke lengths, force settings, and mounting options, our traction springs deliver smooth, reliable retraction and long-lasting performance across multiple industries.

What are traction gas springs?
Traction springs, also known as pull-type gas springs, are designed to provide a controlled pulling force rather than pushing outward. They are used when components need to return smoothly to their original position, helping to prevent slamming, minimise wear, and improve safety. Common applications include doors, hatches, lids, machine covers, and panels.

How do traction gas springs work?
A traction gas strut, or pull gas strut, stores energy inside a pressurized cylinder. When the piston rod is pulled outward, the compressed gas inside applies a contracting force, pulling the rod back in.
This makes them ideal for applications where parts need to return to a closed or resting position.
Traction gas spring materials
We manufacture traction gas springs in a variety of materials and finishes, each selected to match specific performance requirements, environmental conditions, and service life expectations. Material and surface treatments are chosen with careful consideration of factors such as corrosion resistance, load capacity, and exposure levels.
