Torsion Spring

Torsion Spring

A coil that twists, not stretches. Stores rotational energy and exerts torque around its axis.

Torsion springs apply rotational force when twisted. The legs at each end of the coil rotate against each other, storing energy that returns when released. Mousetraps, clothespins, garage doors — torsion is everywhere a mechanism needs to spring back to position.

We coil single-body and double-body torsion springs in left- and right-hand winds, with leg geometries from 90° to 360° turn angles.
