T2N(1.2M) has been calculated for 1200000 revolutions of the output shaft, and T2N(6M) has been calculated for 6000000 revolutions of the output shaft. The application factor KA according to DIN-3990-1 must be considered for each duty cycle and machine type. T2Peak is the maximum output torque the gearbox can tolerate during startups, inversions or other peaks. This value should never be used for continuous operation or for intermittent operation with frequent accelerations. n1N is the rated input speed for continuous operation n1Max is the maximum input speed for intermittent service. For continuous operation at speeds over n1n please inquire Dimensions st_sx-220-dimensions-web-optim.svg
