Constant Force Spring CFS-002
Materials：Including SUS301 and precision steel strips, with customization available to suit your application.
Thickness : 0.04 - 1.0mm
Width : 2.5 - 90mm
Features:Constant force、Safety design、Wide range of applications
Applications:Suitable for products that operate in a linear motion. The force remains consistent during the extension process, and also remains consistent during the retraction process. Overall, the extension force is slightly greater than the retraction force, by approximately 10–20%.

Introduction
[Constant Force Spring] / [Customized Constant Force Spring]
Constant force springs are a special variety of extension spring. They consist of a spiral of strip material with built-incurvature. When the strip is extended the inherent stress resists the loading force, just as in a common extension spring, but at a nearly constant rate.
In use, the constant force spring is usually mounted with a drum and the free end attached to the loading force. This relationship can be reversed, however, with the free end mounted stationary and the constant force spring itself providing the working force, as with carbon brushes in electrical apparatus.
