The Schneider Electric GBX1200081081D carries a current lifecycle flag of Obsolete on the part record, with the product status field listing as current — the official line has been discontinued and the SKU no longer rolls off the factory line. For a pharmaceutical or process line running a Lexium servo coupled to this GBX-Ø 120 mm reducer, the procurement path is the independent surplus channel: traceable stock in sealed packaging, lot and date code confirmed per shipment against an RFQ, with no factory-direct reorder possible. No official successor or Schneider cross-reference appears in the record — the panel builder must either hold a verified surplus spare or plan a reducer swap that accepts the new GBX frame dimensions. ## What the torque, backlash, and efficiency ratings mean in the panel The gearbox delivers 120 N.m continuous output torque with a 192 N.m maximum peak — sized against the application's RMS load, not the peak, because excursions above continuous degrade the grease pack and shorten the 30000 h service life at 100 rpm, 30 °C. Maximum torsional backlash is 8 arc.min, so positioning repeatability sits in the lower-precision end of the planetary class — acceptable for conveyors, mixers, and indexing tables but not for high-precision registration or pick-and-place axes. Efficiency is 96 % for an 8:1 single-stage reducer, and torsional rigidity is 12 N.m/arcmin — the high efficiency reflects straight-cut gears rather than helical, which is also why noise level is 65 dB at 1 m no-load instead of the quieter helical figures. ## Shaft loads, mounting, and the environment envelope Maximum radial force Fr is 1500 N at 100 rpm over a 30000 h life at 30 °C, rising to 2000 N if the duty is capped at 10000 h at the same speed — the belt or pinion load has to be calculated against the curve, not the headline number. Maximum axial force Fa follows the same time-temperature trade-off: 2100 N over 30000 h at 30 °C, or 2800 N at 10000 h at 30 °C — relevant when a sprocket or coupling pushes along the shaft axis. The shaft output carries IP54 protection and the housing is black anodized aluminium with a C 45 shaft, lubricated for life; operating temperature spans -25…90 °C, and the unit can be mounted in any position. ## What replaces it once the surplus runs out For a line still on this reducer, the practical move is to confirm the count of service spares held and quote the volume needed against the RFQ — independent distribution can sometimes surface traceable lot stock that the OEM channel has long since closed.","metaTitle":"GBX1200081081D Schneider GBX Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1200081081D planetary gearbox, 8:1 reduction, 120 N.m continuous, 192 N.m peak, 120 mm frame — obsolete, sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","Noise level":"65 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"1.32 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"192 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":"120 N.m","Gearbox external diameter":"120 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"8 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/61559a76614d6b88b851610b965041f5.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1200081081D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-81-8arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200081081D/alternatives.json"},"ai":{"faq":[{"question":"Who supplies GBX1200081081D and how is it quoted for volume purchases?","answer":"Sourcing runs through independent distribution — quoted to order against the BOM with lot traceability, date code, and packaging condition confirmed per shipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200081081D","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/GBX1200081081D when reusing this data.
