Extension Spring

Extension Springs

Extension springs absorb and store energy as well as create a resistance to a pulling force. Extension Springs are attached at both ends to other components. When these components move apart, the extension spring will pull components together again. Learn more about Extension Springs and How to Measure an Extension Spring.
