Juteng’s compressed gas springs are well-suited for these uses, offering reliable performance in a compact design.

Key Advantages

Simple Installation

Many users choose a single gas strut setup because of its straightforward installation process. With only one mounting point on each side, the setup requires fewer parts and less time to install. This makes it ideal for projects where speed and simplicity are important. Most single damper applications can be completed with basic tools and minimal adjustments.

Cost Savings

A single gas strut setup is often more affordable than dual configurations. Fewer components mean lower material costs and reduced labor expenses. For projects with tight budgets, this setup provides an effective way to achieve smooth operation without unnecessary spending.

Main Limitations

Limited Load Support

A single gas strut can only support a certain amount of weight. If the panel or lid is too heavy, the strut may not provide enough force to hold it open or move it smoothly. In some cases, insufficient force can cause panels to drop or sag, requiring two hands to keep them open. Excessive force, on the other hand, may damage hinges or prevent proper closure. Real-world factors such as friction, seal drag, and uneven weight distribution can also affect performance.

Potential for Uneven Lift

When only one gas strut is used, there is a risk of uneven lifting, especially if the load is not balanced. This can lead to twisting or stress on the mounting brackets. Proper matching of extended length, compressed length, stroke, and end fittings is crucial for smooth operation. Incorrect strut length may prevent full opening or cause stress on the hardware.

Tip: Always consider real-world variables like body flex and wind load when selecting a gas strut for your application.

Best Use Cases

A single gas strut setup is a smart choice for lightweight, low-frequency applications. Juteng’s compressed gas springs offer customizable options to match your specific needs, making them a dependable solution for many projects.

Dual Gas Strut Setup

A dual gas strut setup uses two gas springs, one on each side of a lid, door, or panel. This configuration is common in heavy-duty applications where stability and smooth operation are important. Juteng’s gas springs are designed to handle these demanding tasks with precision and reliability.

Core Benefits

Even Force Distribution

• Dual gas strut setups distribute the load evenly across both mounting points.

• This reduces torsional stress on each gas spring and the connected hardware.

• The result is a balanced motion when opening or closing heavy lids or doors.

When both sides share the load, the dual setup can operate at its best. This configuration helps prevent twisting or bending, which can occur if only one side supports the weight. Even force distribution also means less wear on each component, leading to a longer service life.

Enhanced Stability

• Dual setups provide greater stability for large or heavy panels.

• The operation feels smoother because both sides move together in perfect alignment.

• This precise movement reduces the risk of sudden drops or uneven lifting.

Enhanced stability is especially important for applications that require frequent use or must support valuable equipment. The dual configuration ensures that the motion remains consistent, even under heavy loads or repeated cycles.

Drawbacks

Higher Cost

A dual gas strut setup usually costs more than a single setup. Two gas springs, extra mounting hardware, and more installation time add to the overall expense. However, the investment pays off in terms of safety, durability, and a smoother operation for heavy-duty applications.

Tip: For any application where weight, size, or frequency of use is high, consider a dual gas strut setup for maximum performance and safety.

Gas Strut Force and Performance

Understanding Gas Strut Force

Gas strut force is the amount of pressure a gas spring applies to lift, support, or control a lid, door, or panel. Selecting the correct gas strut force is essential for safe and reliable operation. If the force is too low, the cover may drop suddenly. If the force is too high, the lid may open too quickly or damage the mounting hardware.

How Force Affects Operation

The right gas strut force ensures smooth and controlled movement. It protects users and equipment from sudden falls or slams. Proper force selection also reduces wear and tear, which helps extend the life of the hardware. Here are some key effects:

• Controlled movement prevents accidents and injuries.

• Adequate support keeps the lid or panel stable during use.

• Reduced stress on hinges and brackets increases durability.

• Smooth operation improves user experience.

Note: Always match the gas strut force to the weight and size of your application for optimal safety.

Choosing the Right Force Value

Calculating the correct gas strut force involves several factors. The weight of the cover, the distance from the hinge to the center of gravity, and the angle of operation all play a role. Engineers use formulas to determine the ideal force value:

• Gas Spring Force Calculation:
  F_gas = (W × d_cog × cos(θ)) / (L × sin(α))

• Moment Balance Equation:
  ΣM_hinge = 0
  F_gas × L × sin(α) = W × d_cog × cos(θ)

• Vector Decomposition Method:
  Decompose the weight and force into perpendicular vectors.
  Moment = force × distance.

For example, if a lid weighs 100 N, the lever arm is 0.5 m, and the angle is 45°, the required gas strut force is close to 170 N. At JUTENG, we calibrate the exact F1 force (the nominal force measured at 20°C and 5mm extension) to match your calculation. Our manufacturing capabilities cover a precise force range from 5N to 3000N, ensuring perfect customization for both single and dual setups.

Single vs Dual Force Distribution

Gas strut force distribution changes depending on whether you use a single or dual setup. Each configuration handles loads differently and affects the longevity of the equipment.

Load Handling Differences

A single gas strut must provide all the force needed to lift and support the cover. This setup works well for lightweight applications. In dual setups, the force is split between two gas springs. Each spring shares the load, which reduces stress on the mounting points and hardware.

• Single setups require higher gas strut force per spring.

• Dual setups allow for lower force per spring, improving balance.

• Even force distribution prevents twisting and misalignment.

Tip: For heavy or large covers, dual gas strut setups offer better load handling and stability.

Impact on Longevity

The way gas strut force is distributed affects the lifespan of the equipment. When force is balanced across two springs, components experience less wear. This leads to longer service life and fewer maintenance needs.

• Balanced force reduces wear on hinges and brackets.

• Even distribution prevents warping and misalignment.

• Proper force selection extends the performance of the gas springs.

Juteng’s gas springs are designed for durability and reliability. Customizable installation methods and force values help users achieve the best results for both single and dual setups.

Mounting Considerations

Single Side vs Both Sides

Single gas strut setups require mounting on only one side of the lid or panel. This approach simplifies the installation process. Users need to secure the gas spring between the frame and the moving part. Most projects can be completed with basic tools. The single-side method works best for lightweight covers and small doors.

Dual gas strut setups require mounting on both sides. Each gas spring must be installed in a mirrored position. This method provides better balance and stability for heavy or large panels. The process takes more time and attention to detail. Both gas springs must match in length, force, and mounting angle. This ensures even movement and prevents twisting.

Tip: For heavy or wide panels, always consider a dual setup. It reduces stress on hinges and extends the life of your equipment.

Alignment and Orientation Tips

Proper alignment is critical for smooth operation and long-term reliability. Misaligned gas struts can cause binding, uneven lifting, or even damage to the mounting points. Here are some crucial installation tips:

• Rod-Down Orientation: Always install gas struts with the piston rod facing down. This ensures the internal seal is continuously lubricated by the oil inside the cylinder, reducing friction and preventing nitrogen permeation.

• Measure the mounting points carefully before installation.

• Use a level to check that both sides are even (for dual setups).

• Mark the positions with a pencil before drilling holes.

• Tighten all fasteners securely, but avoid over-tightening to prevent binding.

A well-aligned setup ensures that the gas springs work together. This prevents unnecessary wear and keeps the motion smooth.
