Caution
When using mechanical transmission elements, which subject the shaft end to a
cantilever force, it should be ensured that the maximum limit values, specified
in the cantilever force diagrams, are not exceeded.
Note
Shaft heights 180 and 225
For applications with an extremely low cantilever force load, it should be ensured
that the motor shaft is subject to a minimum cantilever force load as specified
in the diagrams. Lower cantilever forces can cause the cylindrical bearings to roll
in an undefined fashion. This results in increased bearing wear and higher noise.
For these applications, bearing designs for a coupling out-drive should be
selected.
The maximum permissible and the minimum required cantilever forces are shown
in the following diagrams.
