Why Accurate Gas Strut Length Measurement Matters
Accurately measuring gas strut length is essential for proper fit and function, preventing issues like binding, improper sealing, or failure to support weight. Understanding the correct measurements ensures replacements match original specifications or new struts perform as intended. This mechanism is critical for many everyday applications.
- Measure both extended and compressed lengths for full compatibility.
- Identify strut end fittings for secure attachment points.
- Note the rod and cylinder diameters for clearance checks.
- Document force (Newtons) if replacing a worn strut.
Understanding Gas Strut Terminology
Before you start measuring, familiarize yourself with key terms. The extended length is the total length of the strut when fully extended. The compressed length is the total length when fully collapsed. The rod diameter (the shiny shaft) and cylinder diameter (the main body) are also vital specifications. For replacement purposes, understanding the existing strut's force output, often listed in Newtons (N), is equally important; a gas strut for 1967 c10 tailgate, for instance, needs precise force to operate correctly.
You'll often encounter specific fittings on each end. Common types include eyelets, ball sockets, and clevises. These must match the mounting points on your application. Knowing your strut angle bracket or universal strut clamps will also influence how you interpret measurements and install new units.
This mechanism is critical for many everyday applications.
How to Measure Extended Gas Strut Length
Measuring the extended length is generally straightforward but requires attention to detail. You need to find the distance between the centers of the two mounting points (fittings) when the strut is fully extended. If the strut is still installed and functioning, measure from the center of the connection point on the rod end to the center of the connection point on the cylinder end. Ensure the strut is fully extended without forcing it. If the strut is removed, lay it on a flat surface and gently extend it until it stops. Then, measure between the centers of the end fittings.
For example, if you're replacing a gas strut windows system, you'd measure the distance between the pivot point on the frame and the pivot point on the window edge when the window is fully open. This ensures the new strut will hold the window in its highest position without straining the mounting hardware.
The most critical measurement for fit is the extended length between fitting centers.
Always measure from the absolute center of the mounting hole or stud on each end fitting to ensure precision.
How to Measure Compressed Gas Strut Length
The compressed length is measured when the strut is fully collapsed. This measurement is often taken from the center of the rod end fitting to the center of the cylinder end fitting when the rod is pushed as far as it will go into the cylinder. This is crucial for applications where space is limited when the strut is not under load, such as within a closed cabinet or a retracted vehicle component.
If the strut is still installed, you'll need to carefully compress it to find this measurement. This can be challenging and may require two people or a specialized jig, especially for larger struts. If you are dealing with a mini 14 accu strut or similar compact units, the process might be simpler, but care is still needed not to damage the strut or mounting points. The garage door reinforcement strut, for instance, needs accurate compressed length to ensure it doesn't interfere with door mechanisms when closed.
When replacing, consider the application's constraints. A full strut turkey mount, for example, might have specific height limitations when collapsed that dictate the required compressed length.
Understanding the interplay between extended and compressed lengths is fundamental to selecting the correct strut.
This often overlooked dimension is vital for installation clearance.
Additional Measurement Considerations
Beyond basic lengths, other factors influence strut selection. The stroke length, which is the difference between extended and compressed lengths, indicates how much movement the strut provides. For instance, if you have lesjofors gas struts rear specifications for a vehicle, the stroke length is just as important as the overall dimensions for proper articulation.
End Fitting Types
The type of end fittings (e.g., ball socket, eyelet, clevis) must be compatible with your application's mounting hardware. Measure the hole diameter or stud size if you need to source new fittings or ensure compatibility with universal strut clamps.
Force Output (Newtons)
The force, measured in Newtons (N), determines how much weight the strut can support or lift. If the existing strut is weak or you're designing a new system, you'll need to calculate the required force based on the weight of the object being moved and its leverage. This is critical for safety and functionality, preventing unexpected drops or an inability to lift.
Always verify the force (N) requirement if replacing an old strut.
Consult manufacturer datasheets for precise specifications on force and stroke for specific models.
