How to Measure Gas Struts: 5 Easy Steps for Accurate Measurements

Gas struts, also known as gas springs or gas shocks, are ubiquitous in various applications, from car boots and furniture to industrial machinery. Understanding how to accurately measure gas struts is crucial for replacement, repair, or custom design. This comprehensive guide provides five easy steps for accurate gas strut measurement, ensuring you get the perfect fit every time. Proper gas strut measurement avoids costly mistakes and ensures optimal performance.

1. Identifying the Key Gas Strut Dimensions

Before you even start measuring your gas strut, it’s essential to understand what dimensions are critical for proper identification and replacement. Gas struts are identified not only by their physical size but also by their force rating (measured in Newtons). This rating dictates how much force the strut can exert. Failing to measure correctly could lead to a strut that’s either too weak to perform its function adequately or too strong, potentially causing damage.

Understanding the Critical Measurements:

Extended Length (L1): This is the total length of the strut when fully extended. Measure from the center of the eyelet (or mounting point) at one end to the center of the eyelet at the other.
Compressed Length (L2): This measurement is taken when the strut is fully compressed. Again, measure from eyelet center to eyelet center.
Stroke Length (L3): This is the difference between the extended and compressed lengths (L1 – L2). It represents the distance the strut travels during its operation.
Body Diameter (D): The diameter of the cylindrical main body of the gas strut.
Eyelet Diameter (d): The diameter of the eyelets (mounting points) at each end.
Mounting Style: Note the type of mounting points (e.g., ball stud, clevis pin, eyelet). This is crucial for selecting a compatible replacement.
Force (N): This is the most critical specification, representing the force (in Newtons) the gas strut can exert at its fully extended position. Often found stamped onto the strut itself.

2. Gathering the Necessary Tools for Gas Strut Measurement

Accurate gas strut measurement requires the right tools. Improper tools can lead to inaccurate measurements and potentially dangerous situations. To avoid this, make sure you prepare the following:

Measuring Tape: A flexible, accurate tape measure is vital for obtaining precise lengths. A digital caliper can provide even greater accuracy for smaller measurements like eyelet diameters.
Caliper: A caliper is essential for precise measurements of the body diameter and eyelet diameter. Both digital and vernier calipers work well.
Pen and Paper: Always keep a notepad handy to record your measurements. Don’t rely on memory; write down everything.
Camera: Take several pictures of the gas strut from different angles. This is especially helpful when ordering a replacement.

3. Measuring the Extended and Compressed Lengths

Accurately measuring the extended (L1) and compressed (L2) lengths are pivotal steps in gas strut measurement. This is where you’ll need your measuring tape and potentially a helper.

Step-by-Step Process:

Extend the Strut Fully: Ensure the gas strut is fully extended. This will give you the L1 measurement.
Measure from Eyelet Center to Eyelet Center: Carefully measure the distance between the centers of the eyelets at both ends using your tape measure, recording the result as L1.
Compress the Strut Fully: Gently compress the gas strut until it’s fully compressed. This may require some force, so be careful.
Measure the Compressed Length: Measure the distance between the eyelet centers again to obtain the compressed length (L2).
Calculate the Stroke Length: Subtract L2 from L1 to obtain the stroke length (L3).

4. Accurately Measuring the Body Diameter and Eyelet Diameter

Measuring the body diameter (D) and eyelet diameter (d) provides further detail for selecting the right replacement. This is where your caliper comes into play.

Precise Measurement Techniques:

Body Diameter: Carefully position the caliper jaws across the widest part of the gas strut body. Ensure the jaws are perpendicular to the body for an accurate reading.
Eyelet Diameter: Use the caliper to measure the inside diameter of the eyelets. For precise measurements, ensure the jaws are centered in the eyelet.

5. Documenting the Mounting Style and Force Rating

This final step completes your gas strut measurement process. Beyond physical size, the mounting style and force rating (in Newtons) are critical for selecting a suitable replacement.

Crucial Details to Note:

Identify the Mounting Style: Carefully examine the ends of the gas strut. Common mounting styles include ball studs, clevis pins, and standard eyelets. Take photos to ensure you capture these details accurately.
Locate the Force Rating: Most gas struts have their force rating stamped on the body. Look carefully. If it is not clearly visible, you may require further investigation.

6. Using Your Measurements to Find a Replacement

Once you have meticulously measured all parameters, leverage your data to source a correct replacement. Many online retailers and suppliers allow you to filter their gas strut inventory based on the dimensions you’ve collected. Always cross-check your measurements with the supplier’s specifications to ensure a perfect match. Remember that even minor discrepancies can affect the performance and longevity of your new gas strut.

7. Sourcing Accurate Replacement Parts

Finding the precise replacement can be tricky. Many manufacturers exist, and each uses its own numbering system; therefore, knowing the measurements is vital for correctly identifying the gas strut you need. Utilizing online search engines with the specific measurements obtained can aid in this process.

8. Gas Strut Measurement: Preventing Common Mistakes

Avoiding errors in gas strut measurement is important to avoid costly mistakes.

Avoiding Common Pitfalls:

Inaccurate Measurements: Always double-check your measurements. Use multiple tools and techniques where possible.
Incorrect Identification: Carefully examine and document all aspects of the gas strut, including its mounting style and force rating.
Ignoring Force Rating: The force rating is crucial for proper operation. A strut with an incorrect force rating can be dangerous.
Not taking pictures: Taking clear pictures, close-ups, and overall pictures of the current gas strut will help when ordering a replacement.
