(1) Ratio ( i = N in / N out )
(2) Backlash is measured at 2% of Nominal output torque T2N.
(3) Applied to the output shaft center @ 100 rpm .
(4) These values are measured by gearbox with ratio = 10 (1-stage) or ratio = 100 (2-stage) at 3.000 rpm without load.
(5) For continuous operation, the service life is less than 10.000 hrs.

Permitted radial and axial loads on the output shaft

Permitted radial load F2r on center of output shaft X = ½ x L for various output speeds.
Values provided are for 20.000 hours life.

For continue mode (S1), the service life is reduced to 50%.
