Torsion springs operate by flexion. They pull towards their axis by concentric rotation.
All coils in these torsion springs are active. Therefore even the fractions of coils must be taken into account in the calculation.
Available in all dimensions and qualities from 0.25 to 8 mm in wire thickness in small, medium or large series.
