End design of our torsion springs

End forms torsion springs

Everything as you need them for your torsion springs

The requirement controls the end design you should choose for your torsion springs. Lesjöfors can offer any conceivable end design and can even design completely new customised end designs, if necessary.

The forces and tolerances set the limits, and then you have to use lateral thinking!


Unique shank positions are commonly used.
In general, the helix diameter of the torsion spring has to be controlled, either with a shaft or a sleeve.
The torque is force multiplied by the arm. I.e. the further out that the arm is loaded, the smaller is the force available.
Lesjöfors has probably the deepest knowledge in spring design calculation
