Torsion spring single

Cylindrical wound torsion springs are used for axial loads, i.e. a circular movement. When loaded, the wire is exposed to a deflection. Normally, the inside body diameter is mounted on a shaft or similar. Mounting must be carried out in such a way that there is always play between the inner diameter and the shaft. See examples in the tables below.
