That ratio drops a 3000 rpm input motor to about 94 rpm output — typical for indexing conveyors, rotary tables, or positioning axes where you need high torque at low speed without a belt stage. Continuous output torque is 260 N.m at 100 rpm, 30 °C ambient — that is the number for sizing the gearbox into a duty cycle, not the peak figure. Maximum output torque hits 416 N.m at the same speed, but that is for intermittent overloads, not sustained running. The 94 % efficiency means about 6 % of input power turns into heat inside the housing. For a 260 N.m output at 100 rpm (roughly 2.7 kW mechanical), the thermal loss is around 170 W — the black anodized aluminium housing sinks that without forced cooling in most panel-mount or foot-mount installations. ## Service life, backlash, and the real-world limits Rated service life is 30000 hours at 100 rpm and 30 °C — that is about 3.4 years of continuous running. The gearbox is lubricated for life, so no oil-change interval to schedule. Maximum torsional backlash is 12 arc.min — standard precision for a straight-tooth planetary. If your application needs less than 6 arc.min for servo positioning, this box is not the fit; look at a low-backlash or helical planetary instead. Axial and radial load limits are speed-dependent: at 100 rpm, maximum axial force Fa is 2100 N for the full 30000-hour life, or 2800 N if you accept a 10000-hour service life. Radial force Fr at mid-span on the output shaft is 1500 N for 30000 hours, 2000 N for 10000 hours. These are bearing-life limits — overshoot them and the gearbox seizes well before the 30000-hour mark. ## Obsolete — sourcing reality for the GBX1200321402F Sourced through independent distribution against an RFQ. The 120 mm frame size and 32:1 ratio are common enough that a functional cross to a BONFIGLIOLI or SEW-EURODRIVE planetary is possible, but that requires a full interface check (input flange, shaft diameter, keyway, pilot diameter).","metaTitle":"Schneider Electric GBX1200321402F Planetary Gearbox, 32:1","metaDescription":"Schneider Electric GBX1200321402F planetary gearbox, 120 mm diameter, 32:1 reduction, 260 N.m continuous torque at 100 rpm, 94% efficiency.","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":"32:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"3681.9 lbf.in (416 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":"2301.2 lbf.in (260 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":"12 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/aca242e8ed1cf9acd226d70e508d9f0f.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX1200321402F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-321-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200321402F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200321402F","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX1200321402F when reusing this data.
