6.4 Permissible radial load and permissible axial load
Make sure the radial load and axial load received by the output shaft of the motor or gearhead will not exceed the
allowable values shown in the table below.
Note
Failure due to fatigue may occur when the bearings and output shaft of the motor or gearhead are subject
to repeated loading by a radial or axial load that is in excess of the permissible limit.
