At 3:1 reduction, input speed translates directly: 3000 rpm on the motor side yields 1000 rpm on the output. The 94 % efficiency means about 6 % of the input power is lost as heat inside the housing — negligible for most servo axes, but worth accounting for in a continuous-duty thermal budget. ## Lifecycle reality — obsolete, but still specifiable as a critical spare The housing is black anodized aluminium, 80 mm diameter, with a C45 steel output shaft. Shaft output is IP54 — protected against dust ingress and splashing water, but not submersion. The unit is lubricated for life, so no maintenance schedule for oil changes. ## Noise, backlash, and service life — the mechanical envelope Rated noise is 60 dB at 1 m, no-load — quiet enough for a cabinet-mounted axis in a production hall without acoustic enclosure. Maximum torsional backlash is 9 arc-minutes, which places this in the standard-precision range; for a positioning application requiring less than a few arc-minutes of lost motion, a low-backlash or zero-backlash reducer would be needed. Service life is 30,000 hours at 100 rpm and 30 °C — roughly 3.4 years of continuous operation. The radial and axial load limits at that life point are 650 N (radial, mid-shaft) and 900 N (axial). For shorter life targets (10,000 hours), both limits increase: 950 N radial and 1200 N axial.","metaTitle":"Schneider GBX0800031403F Planetary Gearbox, 3:1, 85 N.m","metaDescription":"Schneider Electric GBX0800031403F planetary gearbox, 3:1 ratio, 85 N.m continuous torque at 100 rpm, 94% efficiency, 60 dB noise level.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"60 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6 N.m/arcmin","Maximum output torque":"1203.7 lbf.in (136 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":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"752.3 lbf.in (85 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"9 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/5b41c7a9c211ee347efe97b540e1d8bd.pdf","sourceUrl":"https://www.se.com/uk/en/product/GBX0800031403F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-31-9arcmin-85-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800031403F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX0800031403F?","answer":"85 N.m at 100 rpm and 30 °C.
