Removing the hollow shaft with parallel key

Inadequately fastened gearboxes or geared motors can break loose
Before driving out the machine shaft, fasten a suitably dimensioned means of absorbing
load to the gearbox.
Slightly pretension the pulling equipment so that the gearbox does not drop onto it when
the plug-in shaft is released.
NOTICE
Subjecting stress to the hollow shaft causes bearing failure
It is essential to prevent misalignment when removing the unit.
NOTICE
Excessive forces during removal
Excessive forces can occur during removal of the hollow shaft via the housing.
Stresses in the hollow shaft can lead to bearing failure and damage to the gearbox housing.
Note
