(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. 
(2) T2Max only  for very short time intervals
(3) Up to 1000 times during the gearbox's lifetime
