It delivers 20 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 32 N.m under the same conditions. Rated efficiency is 94 %, and the gearbox is lubricated for life — no maintenance schedule for oil changes. The housing is black anodized aluminium with a C45 steel output shaft, sealed to IP54 at the shaft output. ## Torque, backlash, and load ratings that govern the fit Continuous output torque is 20 N.m at 100 rpm; the maximum intermittent torque reaches 32 N.m at the same speed. Maximum torsional backlash is 28 arc.min — this is the angular play between input and output under reversing loads, a key parameter for positioning accuracy in indexing or pick-and-place applications. The gearbox can handle 200 N axial force (Fa) and 200 N radial force (Fr) for a 10,000-hour service life at 100 rpm and 30 °C. For the full 30,000-hour rated life, both axial and radial limits drop to 160 N. Torsional rigidity is 1.1 N.m/arcmin, which defines how much the output shaft twists under load — relevant for servo-driven positioning where stiffness affects settling time. ## Lifecycle status — obsolete, sourced through independent channels Schneider Electric has marked the GBX0400121402F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a BOM line that requires this exact 40 mm planetary gearbox with 12:1 reduction and 20 N.m continuous torque, the GBX0400121402F remains the only direct fit.","metaTitle":"Schneider Electric GBX0400121402F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0400121402F planetary gearbox, 40 mm diameter, 12:1 reduction, 20 N.m continuous torque, 94% efficiency.
