Basic Information

Mechanical extension springs are designed specifically for a height and weight of a product. The initial tension is the force that holds the coil together and must be exceeded to get the extension spring working. Although the standard initial tension is appropriate for most extension spring needs, initial tension can be customized for specific situations.

Extension springs are commonly used in automotive mechanisms, garage doors, trampolines, washing machines, tools, toys, and equipment in a wide array of industries. Extension spring ends are designed to meet specific application needs. Configurations include hooks, threaded inserts, extended twist loops, crossover center loops, expanded eyes, reduced eyes, rectangular ends and teardrop-shaped ends. Another extension spring configuration features a drawbar spring. In this design, the load at the ends of long, steel loops that pass through the spring center and compress the spring upon loading.
