What this gearbox delivers in a motion train
The GBX0400080552F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, with straight teeth and a 8:1 reduction ratio — sized for servo or stepper motor output stages where compact inline torque multiplication is needed. Continuous output torque is 6 N.m at 100 rpm, with a maximum intermittent rating of 10 N.m — the limiting factor for sizing is the continuous figure, not the peak, since the 30,000-hour service life is quoted at the lower torque. Efficiency is listed at 94 %, typical for a single-stage planetary with straight spur teeth; the 30 arc-min maximum torsional backlash means this is a commercial-grade gearbox, not a zero-backlash precision stage for indexing or positioning tables.

Mounting and environmental limits
Shaft output carries an IP54 rating — the gearbox body is sealed against dust ingress and splashing water at the output shaft, but the motor-mount face and input coupling are not covered by that rating; the IP class applies only to the shaft exit. The gearbox is lubricated for life — no maintenance oil changes required over its 30,000-hour service life at rated load. Maximum radial force at mid-span on the output shaft is 200 N for a 10,000-hour life at 100 rpm; axial force is also 200 N for the same duty cycle. Derate to 160 N axial and radial for the full 30,000-hour target.
