3:1 planetary stage — 28 N.m continuous, 45 N.m peak
The GBX0600031401F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX family, built with straight-cut teeth and a 3:1 reduction ratio. It delivers 28 N.m continuous output torque at 100 rpm and can handle 45 N.m maximum for peak loads, making it a fit for servo-driven indexing tables, pick-and-place axes, and conveyor positioning stages where the motor runs at moderate speed and the load needs a compact single-stage reduction. At 94 % efficiency, the power loss through the stage is low enough that the gearbox runs cool in continuous duty — important when the motor is mounted directly and the assembly is enclosed in a cabinet without forced ventilation.
Torque, backlash, and bearing loads — what the numbers mean for a build
The continuous torque rating of 28 N.m at 100 rpm is the thermal limit for 30000 hours service life at 30 °C ambient — push past it and the gearbox life shortens faster than the torque increase. The maximum output torque of 45 N.m covers acceleration peaks and emergency stops, but the cycle must return to the continuous band for the bulk of the duty cycle. Maximum torsional backlash is 16 arc.min — this is a commercial-grade planetary, not a precision stage. For a positioning axis that repeats to within a few arc-minutes, the backlash is acceptable; for a rotary table holding tighter than 5 arc-min, you need a low-backlash or preloaded planetary. The output shaft carries a maximum radial force of 340 N applied at mid-shaft over the full 30000-hour life, or 500 N if the duty is limited to 10000 hours. Axial force is capped at 450 N under the same conditions. These limits govern the overhung load from a belt pulley or chain sprocket — exceed them and the bearing race spalls before the gear teeth wear. Torsional rigidity is 2.3 N.m/arcmin — the wind-up under the continuous torque is about 12 arc-min, which adds to the backlash for the total positioning error under load.
Lifecycle and sourcing — obsolete, sourced per RFQ
Schneider Electric lists the GBX0600031401F as obsolete — no longer in active factory production.
What ships in the carton — no holes in the kit
The GBX0600031401F ships as a single unit in the package, lubricated for life with no maintenance interval for oil changes. The housing is black anodized aluminium, the shaft is C 45 steel, and the shaft output seal carries an IP54 rating — splash-resistant but not washdown-rated. Ambient operating range is -25 to 90 °C, so it lives in an unheated cabinet or near a warm motor without derating the service life. Noise level is 58 dB at 1 m, no-load — quiet enough for a lab or assembly cell without an acoustic enclosure.
