Hershey Extension Spring
Extension Springs are close-coiled helical springs designed to resist an axial pulling force. Extension Springs or tension springs stretch from free length to a longer extended length to store energy, and offer resistance or provide a restoring force to a pulling force between two points.
Most extension springs are manufactured from round wire and are close wound with initial tension which offers a small deflection load for secure installation. You can design an extension spring with open wound coils when zero initial tension is required or when the spring needs to perform as an extension and a compression spring for the same application. Hershey Spring Solutions manufactures custom extension springs in different lengths and degrees of tension to suit your specifications.
