What’s torsion spring?
Torsion springs is a complex design principle in all spring categories,and the types vary widely,so the theory involved in design is also the most complicated. The ends of the torsion springs are secured to other components that pull them back to their original position as the other components rotate about the center of the spring,creating a torque or rotational force.A torsion spring can store and release energy. The direction of the wind is also important for the application of the torsion spring, since the bearing/attachment position of the leg must be on the left or right side during assembly.
Type of torsion spring and ends
There are two types of torsion spring for you to choose from, one is single-bodied torsion spring, another one is double-bodied torsion springs.
There are many different types of ends for you to choose from, such as short hook ends, straight offset ends, double torsion, hinge ends, straight torsion ends, special ends, and so on.

How to Measure Torsion Springs? Pay attention to the following four elements:
- Wire diameter: Wire diameter is found by placing your calipers on the wire.
- Inner diameter: The inner diameter of the spring is the outside diameter minus the two-wire diameter (d).
- Free length of spring: To measure the free length of spring, place your calipers on the full length of the spring.
- Determine Spring Wind: The right way to determine the direction of wind of a spring is facing it as if looking down the barrel. With torsion springs, you must position it so that the back leg is at the top and in a horizontal position. Whichever way the back leg is pointing will tell you the direction of wind. If it is pointing left, it’s a left handed spring and viceversa
