 Expansion springs, also known as long extension springs, are designed to expand or stretch when force is applied, making them suitable for applications requiring tension.  Long Expansion springs are commonly used in applications such as trampolines, garage doors, and agricultural machinery.

One of the key benefits of adjustable compression springs is their versatility. By simply turning a screw or nut, the spring can be compressed or decompressed to adjust the amount of force it exerts. This makes them ideal for applications where precise control over compression force is required, such as in automotive suspension systems, industrial machinery, and medical devices.
