In production

Extension springs are helical coil springs designed to absorb energy while resisting pulling forces. The further they are stretched, the more force is generate, making them ideal for bringing two components together.

Common applications include Throttle Turn Mechanisms in Automotive, Trampolines, Fitness Equipment and Vibration Dampening Systems.

It is available in both Music Wire material, which is ideal for temperatures between -30 C and +120 C and for use in dry environments, and stainless Steel material, which is ideal for temperatures between -200 C and +250 C and for use in both dry and humid or wet environments. Key Factors to consider when choosing a spring for an application include Spring Material and the Working Environment, Spring Dimensions in both extended and non-extended states.
