OPW Engineered Systems Datasheets for Torsion Springs

Helically wound springs that deflect torque rotationally, torsion springs express mechanical energy through the property of elasticity: the spring action happens when it is twisted rather than compressed or pulled. Despite the name, torsion springs are subject to bending stress--not torsion--as the torque is carried through the length of the wound material.
