Vulcan's Conpower and Power Springs are formed by winding a strip of material on an arbor and into a case or retaining ring to create a compact power source. Conpower springs are pre-stressed to produce a flatter torque gradient than conventional power springs, and can be used to increase the amount of turns in a given case diameter. (read more)

Power Springs and Pre-Stressed Power Springs produce rotational torque from a case or an arbor. Most power springs are designed to the specific application. Please contact Vulcan to discuss your parameters. (read more)
