6.7 Permissible radial load and permissible axial load
Make sure the radial load and axial load received by the motor (gearhead) output shaft will not exceed the allowable
values shown in the table below.
Note If the radial load or axial load exceeds the specied allowable value, repeated load applications
may cause the bearing or output shaft of the motor (gearhead) to undergo a fatigue failure.
