Conpower® Springs and Power Springs
Vulcan Spring is a leading designer and manufacturer of power springs (also known as clock springs), including Conpower® springs and conventional Power Springs. Conpower® is Vulcan Spring’s brand name for its pre-stressed power spring, a brand that is well known and highly respected for quality throughout the world.
Vulcan Spring's Conpower® and conventional 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. Rotational torque is obtained from a center arbor or from the case. This torque increases throughout the total winding of the spring. Conpower®springs, compared to conventional power springs:
- Are pre-stressed to produce a flatter torque gradient
- Can be used to increase the number of turns in a case of a given diameter
Both Conpower® and conventional power springs provide rotational energy from either the arbor or the case, or linear motion with the use of a pulley or cable. Power springs are sometimes referred to as clock springs.

Technical Considerations for Power Springs
Design criteria for both types of power springs - Conpower® springs and conventional power springs - are the same. The decision to use a conventional power spring or Conpower® spring is based on the application. A Vulcan engineer can help with this determination. Important considerations for designing and manufacturing power springs include:
- Arbor size (see A in Diagram)
- Inside diameter (I.D.) of case (See B in Diagram)
- Available case width (See C in Diagram)
- Turns required
- Torque required
- Location of center eye/tab
- Life cycle requirement in total estimated uses
- Environment in which the power spring will be used
- Mounting requirements for case and arbor
