That ratio means the output shaft turns once for every three input revolutions — a common step-down for servo or stepper applications where the motor runs at higher speed and the load needs torque multiplication. Rated efficiency hits 94 %, so only about 6 % of the input power is lost to friction and windage inside the gear train. For a 100 W motor, that's 94 W delivered to the load — the thermal rise stays low enough that the housing stays cool to the touch in most duty cycles. ## Load limits and service life at 100 rpm The gearbox is rated for 30000 hours of service life at 100 rpm and 86 °F (30 °C) ambient — that's about 3.4 years of continuous operation at that speed. The lubricant is sealed for life, so no maintenance interval for grease changes; the unit runs until the bearings or gears wear out. Maximum axial force on the output shaft is 200 N at 100 rpm for a 10000-hour life target, dropping to 160 N if you need the full 30000-hour envelope. Radial force follows the same derating curve: 200 N at mid-shaft for 10000 hours, 160 N for 30000 hours. These limits govern how the load couples to the shaft — an overhung pulley or sprocket that exceeds the radial rating will shorten bearing life fast. Torsional rigidity is 1 N·m/arcmin — meaning 1 N·m of torque twists the output shaft by one arc-minute. For positioning applications, that stiffness combined with the 24 arc.min maximum backlash sets the repeatability floor: under a 10 N·m load, expect about 34 arc.min of total angular error (backlash plus windup). ## Obsolete — sourcing through independent channels Available through independent surplus and broker channels. No stock-holding claim — each procurement is verified against current availability before quoting.","metaTitle":"Schneider Electric GBX0400031403F Planetary Gearbox","metaDescription":"Schneider Electric GBX0400031403F planetary gearbox, 40 mm diameter, 3:1 reduction, 94% efficiency, 24 arc.min backlash.","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":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"1 N.m/arcmin","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","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","Gearbox external diameter":"1.6 in (40 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"24 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/232d4d83d182300b0144b0a3ab2301a1.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0400031403F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-31-24arcmin-11-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400031403F/alternatives.json"},"ai":{"faq":[{"question":"What is the noise level of GBX0400031403F?","answer":"The gearbox is rated at 55 dB measured at 1 m distance under no-load conditions.
