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.
Dimensions: Inner Diameter, Outer Diameter, Wire Diameter, and Spring Length. The Inner Diameter is specified when the spring is required to slip over a mandrel with sufficient clearance to operate freely. The Outer Diameter is specified when the spring is required to fit into a circular hole with sufficient exterior clearance to operate freely, or if there are outer housing clearance issues. The Spring Length is the length of the spring coil.
