Torsion Springs FAQs

1. Does the Load change?
The load on a torsion spring can vary for the same torque and deflection depending upon the position on the leg where the force is applied. The load decreases as the point of contact moves out from the center axis of the spring. If a specific application extends the length of the spring leg, i.e. lever, the lever must be considered as an extension of the leg of the spring.

2. What is the Helix Direction?
A right-hand-wound spring loads in a counter-clockwise direction. A left-hand-wound spring loads in a clockwise direction. Both are available.

3. What is Torque?
Torque is the product of a force times a distance. It is measured in inch-pounds (in the US). Torque should not be confused with Load, which is measured in pounds.

4. What position is Torque measured at?
The Torque "M" listed in the catalog is at the maximum deflection. Since the torque is linear, intermediate torques can be computed by proportion. For example: if a spring is deflected .5 of the maximum value, the torque is .5 of that printed value.
