Torsion springs offer resistance to twisting or torque action.

Torsion Springs It is usually close-wound like the extension spring but with minimum initial tension. There are single bodied and double-bodied torsion springs. The spring legs/ends ultimately deliver the force required in the mechanism. So we can configure custom spring ends to suit the application.

The springs are usually designed to close the application. So careful attention must be paid to give enough clearance for the shaft or arbor that is going through the springs. When defining a torsion spring, the relative position between the legs are critical to apply the necessary force required.

The wire in the torsion spring experience bending force in contrast to torsion force in the compression springs. We can also design torsion springs with square or rectangular wire if required.

Torsion springs are commonly seen in clipboards, counterbalance mechanisms, ratchets and many other machine components.
