Traction Strut vs Compression Gas Strut

Traction Strut Definition
A traction strut is a mechanical device that uses internal gas pressure to pull two parts together. In industrial machinery, this type of strut helps control the movement of equipment that needs a pulling force rather than a pushing force. The traction gas strut works by retracting when force is applied, which means it pulls components toward each other. This action is useful in applications where controlled retraction is necessary for safety or performance.
The traction gas strut features a unique design that allows for smooth and reliable operation. It contains a cylinder filled with nitrogen gas and a piston rod. When installed with the piston rod facing down (to ensure internal seal lubrication), the strut provides consistent force as it retracts. Juteng's traction gas struts are engineered with precision-ground, micro-crack-detected chrome rods for minimal seal wear. Many engineers choose the traction gas strut for its durability and ease of installation. It is often used in situations where precise control over movement is required, such as in adjustable machinery or safety covers.
Compression Gas Strut Definition
A compression gas strut is a device that pushes two parts apart using gas pressure. This type of strut extends when force is applied, which means it pushes components away from each other. The compression gas strut is common in industrial equipment that requires lifting, holding, or opening actions. It is found in applications like machine guards, access panels, and heavy lids.
The compression gas strut consists of a sealed cylinder and a piston rod filled with high-purity nitrogen gas and flame-retardant oil. When compressed, the gas inside the cylinder creates pressure that pushes the rod outward. This action provides support and control for moving parts. Juteng's compression gas struts are manufactured to withstand 10,000-50,000 double strokes and operate within -40°C to +80°C. They are valued for their reliability and long service life.
Key Differences in Force Direction
The main difference between a traction gas strut and a compression gas strut lies in the direction of force they provide. This difference is important when selecting the right strut for industrial applications. The force direction determines how the strut interacts with the equipment and what kind of movement it supports.
The table below shows how each type of gas strut operates:
Type of Gas Strut | Force Direction |
|---|---|
Traction Gas Strut | Pulls parts together |
Compression Gas Strut | Pushes parts apart |
In industrial machinery, the choice between a traction gas strut and a compression gas strut depends on the movement required. If the application needs parts to move closer together, the traction gas strut is the best option. If the equipment must push parts apart or hold something open, the compression gas strut is more suitable.
Tip: Always consider the direction of force before choosing a gas strut. The right choice improves safety, performance, and efficiency in industrial settings.
The traction gas strut stands out in applications where controlled retraction and smooth operation are critical. Its design ensures reliable performance and easy integration into various systems. The compression gas strut, on the other hand, excels in tasks that require strong extension and support for heavy components.
Industrial Applications

Traction Gas Strut Uses
A traction gas strut provides controlled retraction in many industrial settings. This type of strut is often used in adjustable machinery, safety covers, and equipment that requires parts to move closer together. Engineers select a traction gas strut when they need smooth and reliable movement for retracting panels or guiding sliding mechanisms. In assembly lines, a traction strut can help manage the position of guards or shields, ensuring safe operation. Some conveyor systems use traction gas strut designs to maintain tension or control the return of moving parts. These applications benefit from the consistent force and easy installation that a traction gas strut offers.
Compression Gas Strut Uses
A compression gas strut is common in equipment that needs to lift, hold, or open heavy components. Many industries rely on this strut for its ability to push parts apart and support weight. The following table shows some common applications and highlights the effectiveness of compression gas struts in each sector:
Application Sector | Description of Effectiveness |
|---|---|

These examples show how a compression gas strut improves safety, accessibility, and ease of use in many fields.
Suitability for Different Scenarios
Selecting the right strut depends on the movement and force needed in each application. A traction gas strut works best when equipment must retract or pull parts together. This makes it ideal for safety covers, adjustable guides, and tensioning systems. A compression gas strut is better for lifting, holding, or opening actions, such as supporting lids, panels, or access doors. When choosing between these options, consider the direction of force, the weight of the components, and the required motion. Matching the strut type to the specific needs of the application ensures reliable performance and long service life.
Performance Comparison
Load Capacity
Load capacity is a critical factor when selecting between a traction gas strut and a compression gas strut. Each type offers unique strengths for industrial applications. The compression gas strut is often chosen for its ability to lift and support heavy components. It provides robust support for machine guards, access panels, and industrial lids. The strength of the compression gas strut makes it suitable for tasks that require reliable lifting and holding.
The traction gas strut excels in applications where controlled retraction is necessary. It delivers consistent force as it pulls components together. This feature is valuable in adjustable machinery and tensioning systems. Both types of struts are engineered to handle demanding loads, but the choice depends on the direction of force and the specific movement required.
Industrial equipment often relies on gas strut dampers for energy absorption and vibration damping. These dampers control motion speed and reduce noise. They also protect machinery from shock. The movement of the piston through oil in gas strut dampers slows down motion, which helps absorb energy and dampen vibrations. This function improves the overall performance and safety of the equipment.
Safety and Reliability
Safety is a top priority in any industrial setting. Both traction gas strut and compression gas strut designs are built to meet strict safety standards. Unlike common misconceptions, gas struts are maintenance-free - Juteng gas struts are pre-filled with a lifetime supply of flame-retardant oil during production. Regular inspection is necessary to ensure there are no leaks and that the damping response remains consistent. Gas struts are tested to international standards, which helps guarantee their reliability in demanding environments.
Reliability depends on the ability of the strut to maintain its force and function over time. The most common failure modes include drift-down and load-holding issues, which occur when internal seals wear out. This wear can lead to gas bypass and a loss of charge pressure, making the strut ineffective. Jerky movement and high effort can result from side load binding, often caused by misalignment or wear. Predictive replacement schedules help prevent sudden failures and reduce associated costs.
Failure Mode | Description |
|---|---|
Drift-Down and Load-Holding | Caused by internal seal wear, leading to gas bypass and loss of charge pressure, rendering the strut ineffective. |
Jerky Movement and High Effort | Results from side load binding due to misalignment or wear, causing mechanical binding and accelerated wear. |
Predictive Replacement | Establishing proactive replacement intervals based on usage to prevent sudden failures and associated costs. |
Environmental factors also affect safety and reliability. Temperature changes can alter the force exerted by gas springs. For example, a gas spring rated at 200 N at 20°C may perform weaker in colder temperatures and stronger in warmer conditions. High humidity can cause corrosion, especially if the strut is not made from stainless steel. Using the right materials and regular maintenance helps maintain safety and reliability.
Note: Always follow manufacturer guidelines for installation and inspection to maximize safety and service life.
Maintenance and Longevity
Gas struts are maintenance-free - they're pre-filled with a lifetime supply of lubricant during production. This is a critical correction to a common industry misconception. As stated in Juteng's FAQ 12: "No. gas springs are equipped with a lubricant quantity during production that lasts a life time." Instead of maintenance, we recommend a "Proactive Inspection Protocol" that includes:
Wiping the exposed piston rod with a clean, dry cloth during scheduled maintenance (the "10-second rule")
Checking for leaks, wear, and alignment
Inspecting mounting points for integrity
Durability is influenced by the quality of materials and the operating environment. Stainless steel is recommended for humid or corrosive environments to protect seals and extend the life of the strut. Proper installation with the piston rod facing down also contributes to longer service life and better performance. Juteng gas struts reliably deliver a service life of 10,000 to 50,000 double strokes, even in demanding industrial environments.
The pros and cons of each strut type often depend on maintenance needs and expected longevity. Compression gas struts are valued for their strength and ability to handle heavy loads over many years. Traction gas struts offer smooth operation and consistent force, making them reliable for applications that require controlled retraction.
Tip: Schedule regular maintenance and choose the right materials to ensure optimal durability and performance.
