Ensure that the strength of the shaft material is adequate in shrink disc designs. When using typical steels (e.g. C45, 42CrMo4), the torques listed in the
selection tables can be used without restriction. When using material that is considerably weaker, please consult us.
Medium surface roughness Rz must not exceed 15 μm (turning operation is sufficient).
