The 2.62 g.cm² moment of inertia is the figure that matters when this gearbox sits ahead of a servo loop — low enough that commutation bandwidth is not the limit, high enough that belt and coupling stiffness upstream still dominate the resonant picture. ## Shaft loading and the 30,000-hour envelope Maximum radial force Fr is rated at 1500 N at 100 rpm over 30,000 hours at 30 °C, lifting to 2000 N for a 10,000-hour service life; maximum axial force Fa tracks the same duty profile at 2100 N over 30,000 hours and 2800 N over 10,000 hours — the duty class, not the headline force, is the parameter a designer should size against. The unit is lubricated for life, so the 30,000-hour figure at 100 rpm and 30 °C is the published wear budget rather than a maintenance interval — pushing continuous torque toward the 336 N.m peak collapses life proportionally, and ambient operation is rated -25...90 °C. ## Efficiency, acoustics, and shaft sealing Listed efficiency is 94 %, which for a single-stage 9:1 planetary unit is a sensible working point — the loss budget concentrates in the planet bearings and the seal interface, not in the gear mesh itself. Acoustic signature is 65 dB at 1 m under no-load, measured at the gearbox body itself; in a panel build this is the figure to compare against adjacent gear drives when noise is a guard-railing requirement. Shaft output carries an IP54 rating; the gearbox housing itself is not separately sealed beyond the shaft penetration, so a washdown or food-grade deployment needs an external shaft seal or guard at the through-hole. ## Lifecycle status and how the part is sourced now The part is recorded as obsolete on the manufacturer's product status — there is no in-production successor order code on file, so a procurement line against this MPN runs through independent supply rather than the factory channel. Mounting position is unrestricted, the housing is black anodized aluminium, and the shaft material is C 45, so physical integration with a like-for-like replacement is straightforward — the open question for any substitute is whether the reduction ratio, the 120 mm bolt circle, and the 210 N.m continuous rating align with the driven load.","metaTitle":"Schneider Electric GBX1200091081D Planetary Gearbox, 9:1","metaDescription":"Schneider Electric GBX1200091081D planetary gearbox, 9:1 reduction, 120 mm frame, 210 N·m continuous output, listed as obsolete — quoted to order via","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"9:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"2.62 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"336 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N at 100 rpm, during 30000 hour at 30°C 2800 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"1500 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"210 N.m","Gearbox external diameter":"120 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"12 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/fb6600b278e72364d01875f40c28b06f.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1200091081D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-91-12arcmin-210-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200091081D/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings on the GBX1200091081D?","answer":"The headline numbers are a 9:1 reduction, 210 N.m continuous output torque, 336 N.m maximum output torque, 94 % efficiency, 65 dB at 1 m no-load noise, and a 30,000-hour service-life rating at 100 rpm and 30 °C."},{"question":"What shaft load can the GBX1200091081D take?","answer":"Maximum radial force Fr is 1500 N at 100 rpm across the 30,000-hour duty at 30 °C (2000 N for a 10,000-hour life); maximum axial force Fa is 2100 N on the same 30,000-hour duty, rising to 2800 N for 10,000 hours — the shorter-life envelope is the relevant spec when the application runs above the baseline torque."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200091081D","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/GBX1200091081D when reusing this data.
