Maximum output torque reaches 32 N.m (283.2 lbf.in) at the same speed and temperature, with a service life rated at 30,000 hours under those conditions. The straight-tooth planetary design achieves 94% efficiency — the losses are mostly gear mesh friction and bearing drag, so the input power required is roughly 1.06× the output power delivered. ## Mechanical constraints that matter for integration Maximum torsional backlash is 28 arcmin — this is the angular play between input and output when torque direction reverses; for positioning applications that need tighter repeatability, a lower-backlash series is needed. Rated radial force on the output shaft is 200 N at mid-span for a 10,000-hour life, dropping to 160 N for the full 30,000-hour rating; axial force limits are identical. Overhung loads from pulleys or sprockets must stay within these bounds. The shaft output seal carries IP54 protection — fine for dry indoor environments, but washdown or outdoor use needs a secondary cover over the output end. ## Lifecycle and sourcing — obsolete, quoted to order For a drop-in replacement, the buyer must cross-reference the 40 mm frame size, 12:1 ratio, and 20 N.m continuous torque against other planetary gearbox series. Available through independent surplus and broker channels; quantities are confirmed at RFQ. Sourced to order — no stock-holding claim is made.","metaTitle":"Schneider Electric GBX0400120704F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0400120704F planetary gearbox, 12:1 ratio, 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","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/0501580beec44856a911c6e18d3863af.pdf","sourceUrl":"https://www.se.com/ca/en/product/GBX0400120704F/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-121-28arcmin-20-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400120704F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400120704F","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/GBX0400120704F when reusing this data.
