Maximum output torque reaches 32 N.m at 100 rpm, and the unit is lubricated for life — no maintenance schedule for oil changes in the field. ## Torque, efficiency, and noise — what the ratings mean 94 % efficiency means the gearbox loses only 6 % of input power to friction and heat — relevant for sizing the upstream motor and managing thermal rise in a confined enclosure. Noise level is 55 dB at 1 m under no-load — roughly the hum of a quiet office printer — so the unit can run in a lab or assembly area without acoustic treatment. Torsional rigidity is 1.1 N.m/arcmin, which limits angular deflection under load; the maximum torsional backlash is 28 arc.min, so this is not a zero-backlash servo gearbox but works for positioning with moderate precision. ## Environmental limits and shaft loads IP54 at the shaft output means the gearbox is protected against dust ingress and splashing water — suitable for dry indoor machine builds, not washdown zones. Maximum axial force Fa is 200 N at 100 rpm for a 10,000-hour life at 30 °C; maximum radial force Fr is the same 200 N applied at mid-shaft. Both derate to 160 N for a 30,000-hour target. ## Lifecycle — obsolete, sourced through independent channels Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.","metaTitle":"Schneider Electric GBX0400121002F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0400121002F planetary gearbox, 40 mm diameter, 12:1 reduction, 20 N.m continuous 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","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/8ab5211a02fa511fb6299dc664ff74f1.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400121002F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-121-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400121002F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400121002F","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/GBX0400121002F when reusing this data.
