Rotary mechanisms often require controlled torque rather than simple linear force. Constant torque springs can support smooth rotation, return movement, and predictable mechanical behavior in compact assemblies.
Common applications
- Spring-loaded reels and rotary return systems
- Hinges, covers, and controlled opening structures
- Display and positioning mechanisms
- Compact equipment requiring repeatable torque output
Key design inputs
- Required torque and acceptable tolerance
- Rotation angle and working turns
- Arbor diameter, drum diameter, and available space
- Cycle life, noise requirements, and installation method
Selection notes
The best spring design depends on the target torque curve and the final assembly space. Early confirmation of the mechanism layout can reduce redesign time.

FAQ
What is a constant torque spring used for?
It is used when a rotary mechanism needs stable torque, return force, or controlled movement.
Can torque be adjusted?
Yes. Torque can be adjusted by material, strip size, coil diameter, and working turns.
What should be confirmed before production?
Torque range, installation direction, working angle, cycle life, and available space should be confirmed.
