Rated for 32 N.m maximum output torque at 100 rpm and 30 °C ambient, it delivers 20 N.m continuous under the same conditions — the continuous figure is the one to size against for sustained duty cycles. The 94 % efficiency rating means only 6 % of input power is lost to friction and windage at rated load — a meaningful advantage in battery-powered or thermally constrained assemblies where every watt counts. ## Noise, life, and environmental limits Noise output is 55 dB at 1 m under no-load — quiet enough for laboratory or office-adjacent equipment without an acoustic enclosure. Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance access ports or regreasing intervals to schedule. Operating ambient range spans -25 to 90 °C, and the shaft output carries IP54 protection — splash-resistant but not submersible, so position the gearbox above any washdown spray path. ## Sourcing an obsolete planetary gearbox Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ time.","metaTitle":"Schneider Electric GBX0400121401F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0400121401F planetary gearbox, 12:1 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":"12:1","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/22b3263ce482767402ffad8cc47d4caf.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400121401F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-121-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400121401F/alternatives.json"},"ai":{"faq":[{"question":"What is the GBX0400121401F's efficiency rating?","answer":"The listed efficiency is 94 % at rated load — a low-loss planetary design that minimizes thermal buildup in the gearbox housing."},{"question":"What noise level does the GBX0400121401F produce?","answer":"Noise output is 55 dB at 1 m under no-load conditions — suitable for noise-sensitive environments without additional acoustic treatment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400121401F","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/GBX0400121401F when reusing this data.
