Maximum output torque is 32 N·m at 100 rpm and 30 °C ambient — this is the peak intermittent rating, not the continuous duty point. Continuous output torque is 20 N·m at the same speed and temperature — the figure that governs steady-state operation in a conveyor, indexing table, or positioning axis. Exceeding 20 N·m continuously accelerates wear and reduces the 30,000-hour service life at rated conditions. ## Backlash, efficiency, and the straight-tooth trade-off Maximum torsional backlash is 28 arc-minutes — a standard-precision grade for straight-tooth planetary gearboxes. This is adequate for general motion control and simple positioning, but not for high-accuracy indexing or servo axes where sub-arc-minute backlash is needed. Efficiency is listed at 94 %, which is typical for a single-stage straight-tooth planetary at full load. Straight teeth are inherently noisier than helical — the noise level is 55 dB at 1 m, no-load — but they avoid the axial thrust loads that helical gears generate, simplifying bearing selection in the driven assembly. ## Force limits and service life — derating for real loads Maximum radial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life, or 160 N for 30,000 hours — force measured at mid-span of the shaft extension. Axial force limits are identical: 200 N for 10,000 hours, 160 N for 30,000 hours. These are the constraints that govern overhung load capacity from pulleys, sprockets, or direct-coupled loads. The gearbox is lubricated for life — no oil-change interval — and operates from -25 °C to 90 °C ambient. Shaft output sealing is IP54, meaning dust-protected and splash-resistant, suitable for indoor industrial environments but not washdown. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0400200704F as obsolete. No official successor or pin-compatible replacement is recorded from the manufacturer. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ.","metaTitle":"Schneider Electric GBX0400200704F Planetary Gearbox, 20:1","metaDescription":"Schneider Electric GBX0400200704F planetary gearbox, 20:1 reduction, 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":"20:1","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/d3829797878cb29e77928fa30b19e630.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400200704F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-201-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400200704F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0400200704F?","answer":"Continuous output torque is 20 N·m at 100 rpm and 30 °C ambient.
