Helical Torsion Springs are used when there is a need for rotational torque. Both Single and Double Torsion Spring designs are utilized, with Single Torsion Springs being the most common type. When a Torsion Spring is assembled over a shaft, it is important to note that as the spring is rotated in a normal direction, the inner diameter reduces which can cause binding on the shaft along with unnecessary stresses to the spring; it is critical to take into consideration the inside diameter of the spring along with the shaft size it works over.
Spring steels most commonly used in our process for manufacturing Torsion Springs are Oil Tempered, Chrome Silicon, Music, and Stainless Steel wire. Our Torsion Spring manufacturing capacity ranges in wire diameters from .010″ up to .750″, with many of our prototype and short run orders ranging within these sizes. We also have the capability of manufacturing a wide range of Torsion Spring leg configurations. We can supply Torsion Springs with a variety of special finishes or coatings to your specification.
