Torsion Springs:

Torsion springs have a helical design that exerts pressure along a circular path to apply torque, or, in other words, the spring action happens when it is twisted instead of compressed or pulled. The ends of torsion springs are attached to different components which rotate around the center of the spring, which will then recoil to push the components back to their original positions.

Custom Torsion Springs:

Coiling Technologies manufactures torsion springs in a variety of shapes and sizes to meet the needs of your project. Torsion spring legs may be attached to a range of components so end configurations can vary greatly, but our flat table department can design all types of torsion spring ends to fit your requirements. At Coiling Technologies we also offer double torsion springs for special applications like the hatch springs on naval vessels, and our advanced CNC-controlled lathes will make sure your pitch and leg positions remain constant on each and every piece we manufacture.

Designing Torsion Springs:

At Coiling Technologies, Inc. we can custom design your torsion springs to meet a variety of needs, and our engineers can professionally design and produce the right solution for your specific job. Contact us today to learn more about what we can do for you.


Key Parameters

  1. Free Length of Torsion Springs
    1. Length of Torsion Springs being subjected to load.
    2. When designing, remember that a Torsion Springs will grow as it rotates.
  2. Wire Diameter of Torsion Springs
    1. Diameter of the round, square, or rectangular material used in manufacturing the Torsion Springs
  3. Mean Coil Diameter of Torsion Springs
    1. Measurement of the Outside Diameter of the Torsion Springs minus one wire size.
    2. Remember that this will decrease as the Torsion Springs rotates
  4. Wind Direction of Torsion Springs
    1. Torsion springs are only meant to be work in one direction; so always specify the wind direction of the Torsion Springs.
  5. Spring Rate of Torsion Springs
    1. The angular return torque provided per unit of angular displacement of the Torsion Springs.
