Load graphs are accurate if:â— Loads are gradual with no shock loading â— The motor is operating within its designed operating envelope â— Loads are applied to the midpoint of the shaft (no incurring large moments loads)For irregular operating conditions (e. g. shocks, vibrations, cyclic loading, temperature, enviroment) please contact us. 300ST with solid shaft
