 For a metre spring, you need to measure :

  • the diameter of the wire d
  • the external diameter Do
  • the free length Lo
compression metre traction metre

For a compression spring you need to measure:

  • the diameter of the wire d
  • the external diameter Do
  • the free length Lo

compression spring

 

 For an extension spring you need to measure:

  • the diameter of the wire d
  • the external diameter Do
  • the free length Lo
    this is measured to the inside of the loop

For an extension springn

 

For a torsion spring you need to measure:

  • the diameter of the wire d
  • the external diameter Do
  • the length of the free ends E
  • you also need to specify the angle for the free ends (90°, 180°, 270° or 360°)
