Counterbalance systems need stable force, predictable motion, and compact installation. A well-designed constant force spring can help reduce manual effort, support smooth movement, and keep the mechanism reliable over repeated cycles.
Common applications
- Display lift and positioning systems
- Sliding panels, covers, and vertical movement structures
- Industrial equipment with limited installation space
- Products that need stable force over a long stroke
Key design inputs
- Required load and target balancing force
- Working stroke and available drum space
- Cycle life and expected operating frequency
- Mounting direction, end fitting, and safety margin
Selection notes
For counterbalance projects, the spring should be selected around the real working stroke rather than only the maximum load. The installation angle, friction, and guide structure also affect the final feel of the mechanism.

FAQ
Why use a constant force spring in a counterbalance system?
It provides near-constant force over the working stroke, which helps balance weight and improve user operation.
Can the force be customized?
Yes. Strip width, thickness, coil diameter, material, and pre-load can be adjusted according to the target force.
What should be tested before mass production?
Force consistency, cycle life, noise, installation stability, and safety at the end positions should be tested.
