Torsion Springs

A torsion spring is a spring that works by torsion or twisting; that is, a flexible elastic object that stores mechanical energy when it is twisted. When it is twisted, it exerts a force (torque) In the opposite direction, proportional to the amount (angle) it is twisted.

There are two types:

A torsion bar is a straight bar of metal that is subjected to twisting (shear stress) about its axis by torque applied at its ends.

A helical torsion spring, is a metal rod or wire in the shape of a coil that is subjected to twisting about the axis of the coil by sideways forces (bending movements) applied to its ends, twisting the coil tighter.

This terminology can be confusing because in a helical torsion spring the forces acting on the wire are actually bending stresses, not torsional or shear stresses.

Our skilled technicians are experts at producing just the right torsion spring for an array of applications, from large horse float tailgate torsion springs through to very small overhead lighting retaining springs.
