Maryland Precision Spring, an MW Industries Company Datasheets for Constant Force Springs

Constant force springs are a variety of extension spring. A strip of steel with a preset curvature is coiled tightly so that each turn of the strip rests on its inner neighbor. The spring is actuated in a pulling, liner motion with the deflection resistance originating from the material's stiffness and spring construction. Unlike other extension springs, a consistent degree of force is exerted despite the degree of deflection.
