The continuous output torque is 155 N.m at 100 rpm and 30 °C — that's the number to size against your application's duty cycle, not the peak 248 N.m maximum. The 94 % efficiency means about 6 % of input power turns into heat inside the housing. For a 155 N.m output at 100 rpm, that's roughly 100 W of thermal loss — the black anodised aluminium housing sinks that without a fan, but the ambient limit is 90 °C. Backlash is 8 arcmin maximum — acceptable for general positioning and conveyor indexing, but not for a servo-grade rotary table where you'd want 3 arcmin or less. The torsional rigidity is 12 N.m/arcmin, so the windup under load is predictable. ## Obsolete — what that means for procurement Schneider Electric lists this gearbox as obsolete. Stock is sourced through independent surplus channels. Quantities are confirmed at RFQ — no blanket availability claim. The lubricated-for-life design means shelf-stored units don't degrade the way a wet-seal gearbox might. ## Mounting and integration constraints The output shaft is C45 steel, IP54 rated at the shaft exit. Maximum radial force on the output shaft is 1500 N at mid-span for the 30000-hour life target. Axial load capacity is 2100 N under the same duty. Exceed those and the bearing life drops fast — the 10000-hour figures (2000 N radial, 2800 N axial) show the trade-off.","metaTitle":"Schneider Electric GBX1200040702F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX1200040702F planetary gearbox, 4:1 ratio, 155 N.m continuous torque, 94% efficiency, 8 arcmin backlash, IP54.","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":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"2195.0 lbf.in (248 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":"1371.9 lbf.in (155 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/a4197332b16ff9105cc61f5cb8267b72.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200040702F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-41-8arcmin-155-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200040702F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of GBX1200040702F?","answer":"155 N.m at 100 rpm and 30 °C ambient.
