Power springs store rotational energy and release torque in a controlled way. They are widely used in retractable devices, seat belt retractors, cord reels, timers, mechanical return mechanisms, and compact motion-control assemblies.
Common applications
- Seat belt retractors and safety mechanisms
- Cord reels, cable reels, and retractable products
- Mechanical timers and rotary return devices
- Compact assemblies requiring stored rotational energy
Custom design information
For custom power springs, key parameters include torque range, rotation angle, housing size, arbor size, strip width, strip thickness, cycle life, lubrication, and working temperature.

FAQ
What is the difference between a power spring and a spiral spring?
A power spring is a spiral-wound spring designed to store and release rotational energy. It is often used inside a housing with an arbor.
Can power springs be designed for high cycle life?
Yes. Material selection, stress control, lubrication, and correct torque range are important for improving service life.
What applications use power springs?
Typical applications include seat belt retractors, cord reels, mechanical return systems, timers, and retractable devices.
