Traction Gas Spring
Traction gas springs, also called tension gas springs or pull type gas springs, are designed to provide pulling force rather than pushing force. They are used in special motion control applications where reverse-direction force, compact installation, or controlled pulling assistance is required.
Compared with compression gas springs, traction gas springs are typically selected for pull applications, hinged panels, counterbalance systems, hidden access structures, and other motion layouts where pushing support is not suitable. This page helps explain the product concept, typical applications, technical parameters, installation considerations, and customization options in one place.

Overview of Traction Gas Spring
Traction gas springs are designed to provide controlled pulling force for applications where a standard push type gas spring cannot match the required motion path. They are commonly used in structures that need reverse-direction assistance, compact installation, or more controlled balance during movement.
In many applications, traction gas springs help improve motion control, reduce abrupt movement, and support better balance in special opening or closing systems. They are often used in pull applications, hinged panels, counterbalance mechanisms, hidden access structures, flaps, covers, and other special motion control designs.
Depending on the application, traction gas springs can be supplied in standard sizes or customized according to force, stroke, length, fittings, and installation geometry. Correct matching is not only about force level, but also about movement direction, leverage change, and available mounting space.

What Is a Traction / Tension Gas Spring
A traction gas spring is a type of gas spring designed to generate pulling force rather than pushing force. It is also commonly called a tension gas spring or pull type gas spring.
Unlike compression gas springs, which extend outward to support lifting and opening, traction gas springs work in the opposite direction. They are used when the application needs controlled pulling assistance, return force, or a more compact movement solution.
This makes traction gas springs suitable for pull applications, hinged panels, counterbalance systems, and special motion control layouts where standard compression gas springs may not be the right fit.

Quality & Testing
For traction gas springs used in pull applications, hinged panels, counterbalance systems, and other special motion control structures, stable pulling force and reliable long-term performance are especially important.
At Land Gas Spring, quality control and testing are important parts of both product development and production. Because traction gas springs work differently from standard compression gas springs, correct force behavior, sealing reliability, dimensional accuracy, and cycle performance all play an important role in real application results.
Reliable traction gas spring performance depends not only on design, but also on consistent production control, proper material selection, and practical quality verification during manufacturing.
This helps support more reliable performance in pull applications, hinged panels, hidden access systems, counterbalance structures, and other special motion control designs where stable movement and predictable force behavior are important
Typical Applications
Traction gas springs are commonly used in applications where a pulling force is needed to support motion, improve balance, or control movement more effectively. They are especially useful in special layouts where the structure does not allow a standard compression gas spring to work properly.
Hinged Panels
Traction gas springs can be used in hinged panel systems where the movement path requires pulling assistance instead of pushing support.
Counterbalance Systems
Suitable for counterbalance mechanisms that need smoother return force and better movement balance during operation.
Pull Applications
Used in pull applications where the structure requires controlled closing assistance or reverse-direction support.
Hidden Access Panels
Useful for hidden or internal access systems where limited installation space requires compact motion control.
Covers & Flaps
Applied in covers, flaps, and special lid systems that benefit from controlled pulling force and improved movement stability.
Industrial Motion Control
Used in industrial equipment where a pull type gas spring can improve movement control, balance, or structural integration.
Special Door Structures
Suitable for special door layouts and access systems where compression gas springs are not the ideal solution.
Equipment Linkage Systems
For many special motion control designs, traction gas springs provide a practical solution when the required force direction, mounting layout, or movement geometry differs from a standard push type gas spring application.
Cylinder: Gas traction springs consist of a cylindrical tube that houses the other components. The cylinder is usually made of steel and is sealed to contain the gas inside.
Piston: Inside the cylinder, there is a piston that divides the cylinder into two chambers: the gas chamber and the oil chamber. The piston is typically a rod with a seal at one end and a piston head at the other.
Compressed Gas: The gas chamber of the cylinder is filled with compressed gas, often nitrogen. The gas is pressurized, creating a force that pushes against the piston head.
Oil: The oil chamber, located on the opposite side of the piston, is filled with a special hydraulic oil. This oil acts as a damping medium, controlling the speed of the piston's movement and preventing sudden, uncontrolled motions.
Mounting: Gas traction springs are mounted between two points in the application, typically with a ball joint or eyelet at each end. One end is attached to a fixed point, while the other end connects to the moving component.
Installation Precautions
Observe Design Limits
Use gas springs only within their rated load capacities, temperature ranges, and environmental tolerances.
01
Regular Inspection
While gas springs require little maintenance, periodic inspection for signs of wear, leaks, or damage is recommended. Catching issues early helps prevent unexpected failures.
02
Correct Installation
Follow manufacturer guidelines for mounting orientation, alignment, and torque on fittings. Incorrect installation can reduce lifespan or cause malfunction.
03
Avoid Unauthorized Modifications
Never attempt to open, refill, or modify a gas spring unless explicitly designed for adjustment.
04
Safe Disposal
When a gas spring reaches end-of-life, safely release internal pressure and recycle according to local regulations. Specialized recycling may be required for some industrial gas springs.
