This is the kind of compact reducer you spec into a servo-driven indexing table or a pick-and-place axis where the motor needs to run at efficient speed while the load turns slow. Continuous output torque is 120 N.m at 100 rpm and 30 °C ambient, with a maximum intermittent torque of 192 N.m under the same conditions. That 120 N.m continuous figure is the one to design your duty cycle around — the gearbox will run indefinitely at that load without exceeding its 30000-hour service life target. ## Torque, backlash, and service life constraints Torsional rigidity is 6.3 N.m/arcmin, and maximum torsional backlash is 16 arcmin. For a positioning application, that backlash number tells you the angular deadband at the output shaft before the load starts moving — budget it into your repeatability budget if the cycle includes direction reversals. Rated service life is 30000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life, so no oil-change interval to schedule — fit it and forget it until the hour counter hits the replacement threshold. Maximum radial force on the output shaft is 650 N at mid-span for the full 30000-hour life, or 950 N if you accept a 10000-hour service window. Axial force limits are 1200 N for 10000 hours and 900 N for 30000 hours. These overhung-load limits are the ones that trip up a retrofit — if your pulley or sprocket overhangs the shaft, the effective radial load at the bearing must stay under these figures. ## Efficiency and thermal envelope Efficiency is listed at 94 %, which means about 6 % of the input power dissipates as heat inside the housing. For a 120 N.m continuous load at 100 rpm (roughly 1.26 kW output), the heat loss is about 80 W — the black anodized aluminium body sinks that to ambient without a fan, but the operating range of -25 to 90 °C ambient sets the thermal ceiling. Noise level is 60 dB at 1 m, no-load — about the hum of a quiet office printer. Under load the noise will rise, but the straight-tooth design is inherently noisier than helical; if acoustic specs are tight, factor in enclosure attenuation. ## Sourcing an obsolete GBX gearbox For a line-down situation or a critical-spare cabinet, the practical path is a cross-reference to a current planetary gearbox with the same 80 mm frame size, 80:1 ratio, and 120 N.m continuous torque rating. The shaft material is C45 steel and the output seal is IP54 — any replacement must match the shaft diameter and keyway dimensions to avoid a coupling rework.","metaTitle":"Schneider Electric GBX0800801404F Planetary Gearbox, 80:1","metaDescription":"Schneider Electric GBX0800801404F planetary gearbox, 80:1 reduction, 120 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":"60 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"80:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"6.3 N.m/arcmin","Maximum output torque":"1699.3 lbf.in (192 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":"1200 N 100 rpm, during 10000 hour at 30°C 900 N 100 rpm, during 30000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"650 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 950 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1062.09 lbf.in (120 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"3.1 in (80 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"16 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/afd36aa77253cd5e334683bb3a81ab6e.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800801404F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-801-16arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800801404F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0800801404F","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/GBX0800801404F when reusing this data.
