Torsion springs

Torsion springs are available with left or right-hand winding. They can also be supplied with a double helix. The most important parameters in the specification of torsion springs are:

wire diameter
internal diameter
number or coils
leg design
winding direction


We work in most types of spring material, of which the most common are:

EN 10270-1- SM (SS 1774-04) Spring steel
EN 10270-3-1.4310 (SS 2331-06) Stainless steel

We also handle any surface treatment required.
Our modern machines allow us to manufacture torsion springs diameters of 0.20–15 mm.
We supply batch sizes from a single spring to limitless quantity.

Our torsion springs are used in products such as:

Roller blinds, clothes pegs, doors and pliers.


When ordering torsion springs:

State all measurements in mm and forces in N.
Unless stated otherwise, the material used will be spring steel.
Please include requests for special material, surface treatment and any special conditions. If required, we can provide assistance with calculations and dimensioning.

D1 = Wire diameter

Di = Internal diameter – if the spring is controlled externally, please state the external diameter Dy

L0 = Free length

nt = Free length

  • nt = Total number of coils.
  • Please state the winding direction.
  • Please state the leg design.

A1/A2 = Arm length

α° = Angle between the legs in degrees.

Please state the force, if necessary.
We also manufacture double-helix torsion springs.
