(1) T2N value is calculated at n1n, continuous duty cycle, uniform operation, KA=1 and unlimited theoretical life time as per ISO-6336 (NL>N00 in the Woehler line). The application factor KA according to DIN-3990-1 must be considered for each duty cycle and machine type. Generally, T2Peak=2·T2N
(2) Maximum radial force on a solid input shaft
(3) Maximum radial force on the output shaft
