3.4 Permissible radial load and permissible axial load
The radial load and the axial load on the output shaft of the motor (gearhead) must be kept under the permissible values listed
below.
Note
Failure due to fatigue may occur when the motor (gearhead) bearings and output shaft are subject to
repeated loading by a radial or axial load that is in excess of the permissible limit.
