How To Measure A Gas Spring

Gas springs are widely used in a variety of applications, including automotive, machinery, and furniture. Their primary purpose is to provide reliable support for lifting, lowering, and counterbalancing operations. Accurate measurement of gas springs is crucial to ensure proper functionality. In this article, we will explore different methods for accurately measuring gas springs, providing detailed instructions to ensure consistency and safety.

Method 1: Measuring the extended length

The extended length is a critical dimension of a gas spring, representing its fully extended position. To measure this length accurately, follow the steps outlined below:

1. Place the gas spring on a flat surface in its fully extended position, ensuring that it is stable and secure.

2. Use a measuring tape or ruler to measure the distance from the center of one end fitting to the center of the opposite end fitting. Make sure to measure from the center to ensure accuracy.

3. Record the measurement, noting the units (e.g., centimeters or inches) for future reference.

Method 2: Measuring the compressed length

The compressed length is another important dimension of a gas spring, representing its fully compressed position. To measure this length accurately, follow the steps outlined below:

1. Place the gas spring on a flat surface in its fully compressed position, ensuring it is stable and secure.

2. Use a measuring tape or ruler to measure the distance from the center of one end fitting to the center of the opposite end fitting. Again, be sure to measure from the center for accuracy.

3. Record the measurement, including the corresponding units.

Method 3: Measuring the stroke length

The stroke length refers to the difference between the extended length and compressed length of a gas spring. It indicates the total distance the gas spring can travel. To measure the stroke length accurately, follow the steps outlined below:

1. Measure the extended length and compressed length of the gas spring using the methods described above.

2. Subtract the compressed length from the extended length to determine the stroke length. This calculation provides the total travel distance of the gas spring.

3. Record the measurement and units accordingly.

Method 4: Measuring the force

The force of a gas spring represents the pressure it can exert when compressed or extended. Measuring the force accurately is crucial for determining the spring's suitability for specific applications. To measure the force, follow the steps outlined below:

1. Attach the gas spring to a fixed object, such as a wall or bench, ensuring it is securely fastened and cannot move during measurement.

2. Attach a fish scale or a force gauge to the free end of the gas spring, making sure it is accurately aligned with the direction of force.

3. Slowly compress or extend the gas spring, applying an even force until fully compressed or extended.

4. Take note of the reading on the fish scale or force gauge at any given point of travel. This reading represents the force exerted by the gas spring at that specific position.

5. Record the measurement, including the corresponding units.

Method 5: Measuring the diameter

The diameter of a gas spring significantly influences its strength and load capacity. To measure the diameter accurately, follow the steps outlined below:

1. Measure the distance between the center of the piston rod and the outer edge of the cylinder. Ensure the gas spring's components are properly aligned and the measurement is taken at the widest point.

2. Record the measurement, noting the units used for future reference.

In conclusion, accurate measurement of gas springs is essential to ensure their proper functioning and safety. By following the methods described above, you can accurately measure the different dimensions of gas springs, including the extended and compressed lengths, stroke length, force, and diameter. These measurements will facilitate the selection of the right gas spring for your application or the replacement of a faulty one. Always remember to follow the manufacturer's guidelines and consult a professional if in doubt. Proper measurement ensures reliable performance, enhances operational efficiency, and contributes to the overall success of your project or application.
