Constant Force Springs Suppliers in Telford, Pennsylvania

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.

Unlike other extension springs, a consistent degree of force is exerted despite the degree of deflection. (more)
