Torsion springs are typically used to counterbalance mechanical loads. Proper design considerations must be taken to size the spring(s) to perform the work at hand. Leg configuration options are endless from straight legs to multiple bends. Wire diameters of .010”-.625” coiled to specification. Torsion spring loads are typically expressed in inch pounds, similar to a torque wrench. Most torsion springs have a few degrees of pre-load to stabilize assemblies such as simple levers.
