Spiral Torsion Springs

Spiral torsion springs are mechanical components designed to store and release energy by applying rotational force. This rotational force acts in two directions with a “return to center”. The springs deliver a linear torque per revolution. When the deflection exceeds itself, the coils begin to “close-out”, generating friction as they meet. Depending on the spring’s design, the torque will increase rapidly due to the “close-out” friction.

Spiral torsion springs are particularly effective in delivering high torque over a short rotational distance. During manufacturing, these springs are formed into a concentric spiral shape, optimizing their performance for specific applications. Using flat types of steel and their unique shape, spiral torsion springs are best suited for confined spaces.
