(1) Ratio (i=N(in)/N(out))
(2) Backlash is measured at 2% of Nominal Output Torque T(2N)
(3) Applied to the output shaft center at 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 time is less than 10,000 hrs

If radial force F(2r) is not exerted on the center of the output shaft X<1/2xL or X>1/2xL, the permitted radial and axial loads can be calculated by the position load factor Kb on the above diagram.

Permitted radial load F(2r) on center of output shaft X=1/2 x L for various output speeds. Values provided are for 20,000 hours(C) life.

(A) ∅ = Input shaft diameter.
(B) Permitted load values on the output shaft. Please refer to P. 33 glossary.
(c) For continuous Operations(S1), the service life reduced to 50%.
