What are gas struts?
Gas struts or gas springs, utilize compressed air to perform the work of the device. Due to their unique performance advantages, they are widely used in modern industrial design and mechanical engineering. Compared to traditional springs, gas struts provide a smoother and more controlled force output. Making them ideal for controlling the smooth opening and closing of objects. Such as flaps, doors, and windows.
Working principle
The basic principle of gas struts is to utilize the pressure change of the gas inside to generate force. When the gas is compressed, the internal pressure increases, creating an outward thrust. When releasing the pressure, the gas struts return to their original state. This reversible mechanical characteristic makes gas struts excel in load regulation, vibration absorption, and positional positioning.
Key parameters
- Force (F): The force generated by a gas spring, usually measured in Newtons (N). It is key for measuring the performance of gas struts.
- Stroke (S): the maximum distance a gas spring can extend and contract, indicating its range of action.
- Dimensions (D): include the diameter and length of the gas spring. These dimensions are very essential to ensure the fit of the gas spring to the mechanical equipment.
Types
- Free-standing gas struts: allow free movement and are commonly used to easily lift or support heavy objects.
- Locking gas struts: can be locked in any position and are used in applications where a fixed position is required.
- Traction Gas Struts: The opposite of a traditional thrust gas spring, they shorten when force is applied.

- Apply Load: Slowly apply a load to the gas spring until the desired stroke point is reached.
- Record reading: Record the reading on the force gauge when the specific stroke is reached.
Tips: To ensure the measurement is of utmost precision. It is recommended to repeat the measurement several times at different travel points and calculate the average value.
Measuring stroke (S)
- Marking the starting point with the gas struts in the fully un-extended state.
- Measurement of the extended length: Slowly extend the gas struts to their fully extended state and mark it again.
- Calculate the stroke: Measure the distance between these two marked points using calipers.
Tips: Make sure the gas spring stays straight during the measurement process. This avoids bending or twisting which may affect the measurement result.
Measuring diameters(D)
- Measuring Diameter: Measure the outside diameter of the gas spring using calipers. Including cylinder OD and rod OD.
- Measuring Length: Measure the total length of the gas spring in its fully contracted state.
Tips: When measuring the dimensions, make sure the calipers are parallel to the measuring surface. This is to maintain a high accuracy of each measurement.
Recording and analyzing data
- All measurement results are recorded and analyzed as necessary. e.g. mean value calculation or comparison with design parameters.
Assessment and adjustment
- Evaluate whether the gas struts meet the design requirements based on the measurement results.
- If necessary, make adjustments or select a gas strut of a different size.
Tips: During the evaluation process, consider the actual applications and working conditions of the gas struts. This is to ensure that the selected gas struts will meet the actual requirements.
Questions and solutions when measuring gas struts
These solutions enable customers to more effectively address challenges encountered during the measurement process. They can ensure the accuracy and reliability of measurement results. Helps customers optimize their manufacturing processes and product designs. They also improve the performance and satisfaction of the final product.
Unstable readings when measuring force
Ensure that the force gauge being used is properly calibrated. Make sure that the load is applied steadily during the measurement. Avoid rapidly changing loads as this can lead to fluctuating readings. In addition, check if there are disturbing factors in the working environment. Such as vibration or temperature fluctuations, which can affect measurement accuracy.
Inconsistent stroke
When measuring the stroke, make sure that the gas struts remain straight from fully contracted to fully extended. Use a high-quality measuring tool and repeat the measurement several times under the same conditions to calculate the average value. Inconsistencies may be caused by inaccuracies in the measurement method or variations in the gas spring itself.
Unsure how to choose the right measuring tool
The selection of a suitable measuring tool depends on the specific requirements. For force, electronic force gauges are recommended as they provide accurate and easy-to-read results. For stroke and dimensions, use highly accurate calipers or digital slide rules. Make sure all tools are suitable for the size range and accuracy requirements you need to measure.
How to secure the measurement process
When handling high-force or large-size gas springs, you need to wear appropriate personal protective equipment (PPE). Such as safety glasses and gloves. Ensure that the work area is clean, tidy, and free from any obstacles that could cause slips or trips. Follow all our safety guidelines and recommendations when applying loads or taking measurements.
The mismatch between gas strut specifications and design parameters
If the measurement results show that the actual specifications of the gas struts differ significantly from the design parameters. First, confirm the accuracy of the measurement method and tool. If the measurements are confirmed to be correct, consider communicating with the supplier. Design modifications might be required or change the gas spring specifications.
