*
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.
Th average surface roughness Rz must not exceed 15 μm (turning
operation is sufficient).
