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.
Medium surface roughness Rz must not exceed 15 μm (turning operation is sufficient).
Output flange and hollow shaft with shrink disc (output design SAK) are not possible in the same position.
For other dimensions, see Gearboxes/geared motors with hollow shaft (output design H
