Hollow shaft with shrink disc
Dimensions in [mm]
* 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. The average surface
roughness Rz must not exceed 15 μm (turning operation is sufficient).
