What the torque ratings mean for your drive train
The GBX0600051403F delivers 40 N.m continuous output torque at 100 rpm and 30 °C ambient, with a maximum intermittent peak of 64 N.m under the same conditions — the continuous figure is the one to size against for duty cycles above 60 %. Rated service life is 30,000 hours at 100 rpm and 30 °C; the torque and force ratings (axial 450 N, radial 340 N at mid-shaft) all reference this life target, so exceeding any one parameter shortens the service window proportionally.
Sourcing an obsolete planetary gearbox
Schneider Electric lists this GBX series gearbox as obsolete — no direct successor order code is published, so replacement relies on independent surplus and broker channels. The 60 mm diameter, 5:1 straight-tooth planetary with 16 arc.min backlash and 40 N.m continuous torque defines the mechanical envelope; any substitute must match the output shaft interface (C 45 steel) and the IP54 shaft seal to drop into the same mounting footprint.
Mechanical integration checklist
Black anodised aluminium housing, 60 mm external diameter, shaft output sealed to IP54 — the gearbox mounts directly to the motor face and the output shaft carries the load; no additional enclosure protection is needed for the gearbox body itself in a dry cabinet. Lubricated for life — no oil-change interval to schedule, which simplifies MRO spares planning but also means the gearbox is a sealed unit; a leak or contamination event requires full replacement, not a re-lube.
