Continuous duty is lower at 20 N.m under the same conditions, so the application must not exceed that sustained load. Service life is 30,000 hours at 100 rpm and 30 °C with the 20 N.m continuous torque. The gearbox is lubricated for life — no maintenance interval for oil changes, but the sealed grease limits the thermal envelope. ## Shaft loading and mounting constraints Maximum axial force (Fa) is 200 N for a 10,000-hour life at 100 rpm and 30 °C, dropping to 160 N for the full 30,000-hour service life. Radial force (Fr) follows the same derating curve — 200 N at 10,000 hours, 160 N at 30,000 hours, measured at mid-span on the output shaft. The shaft output carries an IP54 rating — splash-proof from the shaft side, but the housing itself is not sealed for washdown. The black anodized aluminium housing and C45 steel shaft are standard for dry indoor environments. ## Backlash and noise profile Maximum torsional backlash is 28 arc-minutes — this is a standard-precision straight-teeth planetary, not a zero-backlash unit. For positioning applications requiring repeatability under 0.5°, the 28 arc-min play needs to be accounted for in the servo tuning or mechanical preload. Noise level is 55 dB at 1 meter under no-load conditions — quiet enough for most machine-tool or conveyor applications without additional acoustic enclosures. The 94 % efficiency means about 6 % of input power is lost as heat through the gear mesh and bearing friction.","metaTitle":"Schneider Electric GBX0400121403F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0400121403F planetary gearbox, 12:1 ratio, 32 N.m max 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","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","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/195050a67a001147d6081cad9fcd40af.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX0400121403F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-121-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400121403F/alternatives.json"},"ai":{"faq":[{"question":"How can I order GBX0400121403F or check availability?","answer":"Submit an RFQ for current availability, pricing, and lot quantities — no stock-holding claim is made here; every shipment is confirmed before order commitment."},{"question":"What is the continuous torque rating of GBX0400121403F?","answer":"Continuous output torque is 20 N.m (177.01 lbf.in) at 100 rpm and 30 °C ambient.
