Materials：Including SUS301 and precision steel strips, with customization available to suit your application.Thickness：0.04 - 1.0mmWidth：2.5 - 90mmFeatures：Constant force、Safety design、Wide range of applicationsApplications：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%.

Materials：Including SUS301, SAE1080, SK5 and precision steel strips, with customization available to suit your application.Thickness：0.04 - 1.0mmWidth：2.5 - 90mmFeatures：The steel strip is wound around a central arbor, starting from a naturally relaxed state. It offers a gentle torque curve, making it ideal for short travel distances and continuous release. The design allows for simple assembly and convenient operation.Applications：Used in devices that required fewer spring turns to operate, such as car window regulators, toys, rowing machines (fitness equipment), clocks, and others.

Materials：Including SUS301 and precision steel strips, with customization available to suit your application.Thickness：0.04 - 1.0mmWidth：2.5 - 90mmFeatures：Pre-wound with internal pre-stress, delivering stable and high torque with quick response. Offers long service life, high reliability, easy assembly, and user-friendly operation.Applications：Used in devices that require a higher number of spring turns to operate, such as fall arresters, air (or water) hose retractors, and automotive seat belts.

Materials：Including SUS301 and precision steel strips, with customization available to suit your application.Thickness：0.04 - 1.0mmWidth：2.5 - 90mmFeatures：Suitable for various motor carbon brushes, provides smooth and stable output, long service life.Applications：Used in electric motors (vacuum cleaners, power tools, industrial fans), generators, electric drills.

Materials：Including SUS301 and precision steel strips, with customization available to suit your application.Thickness：0.04 – 0.3mmWidth：2.5 - 90mmFeatures：rotational movement, consistent force output.Applications：automatic cable retraction, counterbalancing weights, and power sources.
