Cantilever/axial force diagrams
General information, refer to Chapter AL A.
Cantilever force
Caution
!
When using mechanical transmission elements, which subject the shaft end to
a cantilever force, then please observe that the maximum cantilever force,
specified in the cantilever force diagrams, is not exceeded.
Note for shaft heights 180 and 225
For applications with extremely low cantilever force stressing, it should be en-
sured that the motor shaft has a minimum cantilever force, specified in the
diagrams. Lower cantilever forces can result in the cylindrical roller bearings
rolling in an undefined fashion. This can result in increased bearing wear and
higher noise.
For these applications, the bearing design should be selected for a coupling
out–drive.
The maximum permissible and the minimum required cantilever forces are
shown in the following diagrams.
