Its 8:1 reduction ratio delivers 120 N.m continuous torque at 100 rpm and 30 °C, with a maximum intermittent rating of 192 N.m at the same speed and temperature. Efficiency sits at 94 %, meaning about 6 % of input power is lost as heat through the gear mesh — typical for a single-stage planetary with straight teeth. The 8 arc.min maximum torsional backlash is standard for precision positioning in indexing or pick-and-place axes where cumulative error matters. ## Rated life and load limits Service life is specified at 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no field re-greasing interval. At the same speed and temperature, maximum axial force (Fa) is 2100 N for the full 30,000-hour life, or 2800 N if you accept a 10,000-hour service window. Radial force (Fr) applied at mid-span on the output shaft is 1500 N for 30,000 hours, 2000 N for 10,000 hours. The shaft output seal is rated IP54 — fine for dry indoor environments but not washdown. Housing is black anodized aluminium; the shaft is C45 steel. Operating ambient range is -25 to 90 °C. ## Obsolete — sourced through independent channels Schneider Electric lists the GBX1200081403F as obsolete. This gearbox is available through independent surplus and broker channels — quantities are lot-specific, and condition (new-in-box, sealed) is confirmed at RFQ time. A functional replacement would require a different frame size or ratio — a mechanical re-design.","metaTitle":"Schneider Electric GBX1200081403F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1200081403F planetary gearbox, 8:1 ratio, 120 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":"65 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"1699.3 lbf.in (192 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1062.09 lbf.in (120 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"8 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/6e3b80a079f8d652be1f32d706f026f9.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200081403F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-81-8arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200081403F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX1200081403F?","answer":"120 N.m (1062.09 lbf.in) at 100 rpm and 30 °C.
