5.4 Permissible overhung load and permissible
thrust load
The overhung load on the motor’s output shaft or gear output shaft must be kept
within the permissible values listed below.
Note
Failure due to fatigue may occur if the motor’s bearings and output shaft
are subject to repeated loading by an overhung or thrust load that is in
excess of the permissible limit.
