What this planetary gearbox delivers
The GBX0400081402F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, with straight teeth and an 8:1 reduction ratio. It delivers a continuous output torque of 6 N.m (53.1 lbf.in) at 100 rpm and 30 °C, with a maximum output torque of 10 N.m (88.5 lbf.in) under the same conditions. Efficiency is listed at 94 %, meaning about 6 % of input power is lost to friction and heat — typical for a single-stage planetary of this size. The torsional rigidity of 1 N.m/arcmin tells you how much the output shaft twists under load; at the continuous torque of 6 N.m, expect about 6 arcminutes of windup.
Backlash, noise, and service life — the real-world numbers
Maximum torsional backlash is 30 arcminutes — that is the angular play between input and output when reversing direction. For positioning applications where repeatability matters, this is the spec to watch; a lower-backlash gearbox would be needed for servo-grade indexing. Noise level is 55 dB at 1 m, no-load — roughly the sound of a quiet office. Service life is rated at 30,000 hours at 100 rpm and 30 °C, and the gearbox is lubricated for life, so no maintenance re-greasing is required. The shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion. The housing is black anodized aluminium, and the shaft material is C45 steel.
Obsolete status and how to source it
Schneider Electric has marked the GBX0400081402F as obsolete. No official successor part number is listed by the manufacturer, so any replacement would need to be a parametric cross — same 40 mm frame, 8:1 ratio, and 6 N.m continuous torque. We source this gearbox through independent distribution channels. Same part, different passport — genuine is genuine, and we handle the cross-region logistics.
