Maximum radial load Fr is 1,500 N at 100 rpm over 30,000 h and rises to 2,000 N at 100 rpm over 10,000 h; maximum axial load Fa is 2,100 N at 100 rpm over 30,000 h and 2,800 N over 10,000 h — the higher figures apply only at the shorter life target. ## Precision, stiffness, and efficiency Maximum torsional backlash is 12 arc.min and torsional rigidity is 13 N.m/arcmin, with a moment of inertia of 1.3 g·cm² — positioning this unit on the standard-precision side of the GBX line, suited to motion control where repeatable indexing matters but ultra-low backlash is not required. Efficiency is 94 % at the gear stage and noise level is 65 dB at 1 m on no-load — consistent with a straight-tooth planetary stage; helical or low-noise variants would be quieter at the cost of higher cost and a different ratio ladder. ## Lifecycle status and supply posture The GBX1200400703D has been cross-referenced in the OEM catalogue as a GBX-series planetary gearbox with a 40:1 ratio and 120 mm frame; buyers fitting a replacement should confirm the output shaft diameter, pilot flange, and motor adapter plate against the mating servo before committing to a substitute, since a same-family alternative is not guaranteed to be a drop-in mechanical replacement.","metaTitle":"Schneider GBX1200400703D Planetary Gearbox, 40:1, 230 N.m","metaDescription":"Schneider GBX1200400703D — Ø 120 mm planetary gearbox, 40:1 reduction, 230 N.m continuous output, 12 arc.min backlash.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"40:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"1.3 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"368 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N at 100 rpm, during 30000 hour at 30°C 2800 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"1500 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"230 N.m","Gearbox external diameter":"120 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"12 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/87b10404ab484c81282ebcbc7eafcf3d.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200400703D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-401-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200400703D/alternatives.json"},"ai":{"faq":[{"question":"What is GBX1200400703D's listed efficiency (94 %) on this Gear Reducers & Gearboxes line?","answer":"The datasheet efficiency is 94 % at the gear stage, consistent with a straight-tooth planetary reducer of this frame size; the figure is the mechanical efficiency of the gear train and does not include motor losses."},{"question":"What is GBX1200400703D's listed noise level (65 dB at 1 m, no-load) on this Gear Reducers & Gearboxes line?","answer":"Noise level is specified as 65 dB at 1 m on no-load, measured at the gearbox body rather than at the driven load — typical of a straight-tooth planetary stage and louder than helical equivalents at the same ratio."},{"question":"Who supplies GBX1200400703D and how is it quoted for volume purchases?","answer":"The part is sourced to order through independent distribution.
