The permissible axial forces are shown in the diagrams for the appropriate mo-
tors.
!
Caution
For motors with integrated holding brake, no axial forces are permitted!
When using, e.g. gear wheels with helical teeth as the drive element, in addition
to the radial force, the bearing is also subject to an axial force. For axial forces
acting towards the motor, the bearing alignment force can be overcome, so that
the rotor can move corresponding to the actual bearing axial play (to 0.2 mm).
The permissible axial force can be approximated using the following formula:
F
A
= 0.35 F
Q
More accurate data can be taken from the diagrams, taking into account the
mounting position.
