Adjustable Locking Gas Strut

How Adjustable Types Work
Adjustable locking gas struts use a combination of pneumatic force and a precise locking mechanism. Inside the strut, a pressure tube holds compressed gas. A piston moves within this tube. When the strut is unlocked, the gas pushes the piston, allowing smooth movement. The user can activate an internal valve to lock the piston at any point along its stroke. This design lets you hold a load securely in any position, making it ideal for situations where the required position or force may change.
Note: This variable positioning is possible because of the internal valve system and the balance between gas pressure and hydraulic oil inside the strut.
Features and Benefits
Adjustable locking gas struts offer several distinct advantages:
Flexible Positioning: Users can lock the rod at any position, not just preset points.
Precise Control: The mechanism allows for fine adjustments, which is useful during prototyping or when requirements are uncertain.
Safety and Stability: The strut holds loads securely, reducing the risk of sudden movement.
Customization: Juteng offers a wide range of options, including force ratings from 50N to 2000N, different stroke lengths, and various end fittings. Materials like stainless steel are available for harsh environments.
Juteng’s product range covers many needs. For complex projects, you can utilize Juteng's free computer-aided gas spring design services to calculate the exact F1 force and mounting geometry.

Locking Gas Strut Comparison
Adjustability & Versatility
Adjustable locking gas struts stand out for their ability to lock and unlock at any position along the stroke. This feature gives users more control and flexibility. For example, in custom machinery or medical equipment, the need to stop at different points is common. Adjustable types allow for this, making them ideal for projects where requirements may change over time. Fixed locking gas struts, on the other hand, have preset positions. Once installed, they offer limited adjustability. This makes them suitable for applications where the movement is consistent and does not need frequent changes.
The versatility of adjustable locking gas struts has led to their widespread use in automotive, furniture, and industrial sectors. They provide controlled lifting and lowering of heavy loads, which improves ergonomics and safety. Fixed types are more common in routine applications, such as cabinet doors or machinery covers, where the same action repeats daily.
Note: Adjustable locking gas struts are often chosen for projects that require frequent adjustments or fine-tuning, while fixed types are best for stable, repetitive tasks.
Ease of Use
Fixed locking gas struts are known for their simplicity. Users can install them quickly and operate them with minimal effort. The locking mechanism works automatically at preset positions, so there is little need for adjustment after installation. This makes fixed types a popular choice for furniture, home appliances, and other daily-use items.
Adjustable locking gas struts require more setup. Users must determine the correct position and activate the locking mechanism as needed. This process may take more time, especially during the initial installation or when frequent changes are necessary. However, the added flexibility can be valuable in environments where requirements are not fixed.
Fixed types: Simple operation, minimal training needed
Adjustable types: More setup, but greater control
Reliability & Maintenance
Both adjustable and fixed locking gas struts are designed for durability, but maintenance needs can differ. Over time, all gas struts may face issues such as loss of pressure, oil leakage, or sticking due to dirt. Proper installation and regular checks help maintain performance.
Here is a table summarizing common maintenance issues:
Maintenance Issue | Description |
|---|---|
Loss of Pressure | Struts can lose gas over time, leading to reduced force and functionality. |
Oil Leakage | Fluid leaks can occur, often indicating a seal failure. |
Sticking or Binding | Dirt or debris can cause struts to stick, affecting smooth operation. |
Corrosion | Exposure to moisture can lead to rust and deterioration of the strut’s exterior. |
Overloading | Exceeding the weight capacity can damage the strut and shorten its lifespan. |
Misalignment | Improper installation can lead to uneven force distribution and premature wear. |
⚠️ Safety Warning: Gas struts are filled with high-pressure nitrogen (up to 8-10 MPa) and are completely irreparable. Never attempt to open or repair a leaking strut, as it can cause an overpressure burst releasing deadly high-speed debris. Always replace worn units.

Choosing the Right Type
When to Pick Adjustable
Adjustable locking gas struts work best in situations where flexibility is important. These struts allow users to lock the rod at any position, making them ideal for projects that require frequent changes or fine-tuning. Prototyping is a common example. During the design phase, engineers often need to test different positions and forces. Adjustable types make this process easier.
When selecting an adjustable locking gas strut for prototyping, consider the following factors:
Force range and load behavior
Stroke length and cylinder dimensions
Rod diameter
Mounting orientation
End fittings and accessories
Environmental conditions, such as temperature, corrosion, or hygiene requirements
Applications with uncertain force requirements also benefit from adjustable types. Variable gas struts allow pressure adjustment, which helps users find the right force. Some designs offer elastic locking for minor adjustments, while others provide rigid locking for complete stability.
Tip: Adjustable locking gas struts are a smart choice for medical equipment, custom furniture, and machinery where requirements may change over time.
When to Pick Fixed
Fixed locking gas struts are best for applications with consistent, repetitive movements. These struts lock only at preset positions, which simplifies installation and daily use.
