Power Spring

A power spring is a flat strip of steel coiled into a spiral that works like a compact energy storage device. When the spring is wound up, it stores energy as torque, and as it unwinds, it releases that energy smoothly to create a steady, turning motion. This makes it ideal for mechanisms that require a smooth return movement or controlled retraction, rather than a sudden pull.

Made from high-carbon steel or stainless-steel strips, Teng Yao’s power springs combine excellent fatigue resistance with stable torque output. The lineup includes open-band designs for compact assemblies like timers and clocks, multi-layer types for long-stroke or heavy-duty retraction systems, and housed versions for convenient integration in seat-belt retractors, vacuum cleaners, and other automatic rewind mechanisms.

Power Spring PS-001

Power Spring PS-001

Materials:Including SUS301, SAE1080, SK5 and precision steel strips, with customization available to suit your application.
Thickness:0.04 - 1.0mm
Width:2.5 - 90mm

Features: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.
