Maximum intermittent torque reaches 32 N.m at the same speed — the margin matters if your application sees occasional overloads like a jam or a hard start. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this size. The noise level of 55 dB at 1 m, no-load, is quiet enough for most production-floor environments — you won't hear it over a conveyor drive or a pump motor. Torsional backlash is rated at 28 arc-min maximum. That's a standard-precision grade — fine for positioning conveyors, indexing tables, or general motion axes, but not for a CNC ballscrew or a robot joint where you'd want sub-10 arc-min. ## Sourcing reality — obsolete, but available through surplus channels Schneider Electric lists the GBX0400120702F as obsolete. This gearbox is sourced through independent surplus and decommissioned-line channels. Quantities are lot-specific — confirmed at RFQ. ## Mechanical limits — axial and radial load capacity Maximum axial force (Fa) is 200 N at 100 rpm for a 10,000-hour life at 30 °C, derating to 160 N for a 30,000-hour target. Radial force (Fr) follows the same curve: 200 N at 10,000 hours, 160 N at 30,000 hours, with the load applied at mid-span on the output shaft. The shaft is C45 steel, the housing is black anodized aluminium, and the IP54 rating on the shaft output means it keeps dust and splashing water out — fine for a dry indoor machine, but not for washdown. The gearbox is lubricated for life, so no maintenance schedule for oil changes. That covers most indoor industrial environments, but if your enclosure sits next to a furnace or in a freezer, check the thermal margin against the continuous torque derating.","metaTitle":"Schneider GBX0400120702F Planetary Gearbox, 12:1, 20 N.m","metaDescription":"Schneider Electric GBX0400120702F planetary gearbox, 40 mm diameter, 12:1 ratio, 20 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"55 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"12:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"1.1 N.m/arcmin","Maximum output torque":"283.2 lbf.in (32 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N 100 rpm, during 10000 hour at 30°C 160 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"200 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Continuous output torque":"177.01 lbf.in (20 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"1.6 in (40 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"28 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5e27060354e0f0f35ae78831acb79bce.pdf","sourceUrl":"https://www.se.com/uk/en/product/GBX0400120702F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-121-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400120702F/alternatives.json"},"ai":{"faq":[{"question":"What is GBX0400120702F's continuous torque rating?","answer":"20 N.m (177.01 lbf.in) at 100 rpm and 30 °C ambient.
