Admissible load on output shaft

Based on 15,000 hours life and use of synthetic oil ISO VG150
Kr = Admissible radial on output shaft
Ka = Admissible axial load under tension or compression
l = Distance between the end face and the application point of the radial load (mm)
L = Shaft length (mm)

Output speed Loads l = 0 l = 1/4L l = 1/2L l = 3/4L l = L
