 Permissible overhung load and permissible thrust load
Make sure the overhung load and thrust load received by the output shaft will not
exceed the allowable values shown in the table below.
Note
If the overhung load or thrust load exceeds the specified allowable value,
repeated load applications may cause the bearing or output shaft of the
gearhead to undergo a fatigue failure.
