These springs are designed with heavier material than the clock spring and generate higher torques over shorter degrees of rotation. The other style of spiral wound spring that we build is the spiral torsion spring, often called a power spring. Power springs are used to store and release rotational energy. When used, these springs are wound on an arbor and are typically restrained in a cylindrical case. The small size and rotational output of Power Springs make them fantastic options for manufacturers and engineers.Power springs are springs that are made from a strip of flat, spring tempered material that has been tightly wound in a flat spiral shape.

Power spring Power Springs are used to create a compact power source in applications that require counterbalancing, sometimes through a cable/cord retraction mechanism.
