Continuous output torque is 120 N.m at 100 rpm, with a maximum intermittent rating of 192 N.m — the 120 N.m figure is the one to size against for duty cycles above 60% utilization; the 192 N.m ceiling covers acceleration peaks and occasional overloads within the 30000-hour service life at 30°C. Efficiency is 94%, which means about 6% of the input power is lost as heat inside the housing — for a 1 kW motor that is 60 W of thermal load the black anodized aluminium housing must dissipate; the housing material and colour are not cosmetic — anodized aluminium radiates better than painted steel in the same envelope. ## Backlash, stiffness, and bearing loads — positioning accuracy constraints Maximum torsional backlash is 16 arc.min — for a single-direction positioning axis this is the lost motion at reversal; for a bidirectional indexing application the 16 arc.min appears as a dead band the controller must compensate for or the mechanical system must preload against. Torsional rigidity is 6.3 N.m/arcmin — under the 120 N.m continuous load the output shaft twists about 19 arc.min from the no-load position, which adds to the backlash figure and must be budgeted in the total positioning error calculation. Maximum axial force on the output shaft is 1200 N at 100 rpm for a 10000-hour life, derating to 900 N for the full 30000-hour service life — if the application applies thrust (from a leadscrew or helical gear), the 900 N limit governs the bearing life; radial force is 650 N at mid-span for 30000 hours, rising to 950 N for a 10000-hour duty. ## Obsolete — sourcing the GBX0800800704F through independent channels Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical replacement is documented by Schneider — a substitution would require verifying the mounting flange, shaft diameter, and input interface against the existing installation. The gearbox is lubricated for life — no oil-change interval to plan for, which simplifies MRO spares storage but means the unit is sealed and cannot be re-greased if the service life is exceeded.","metaTitle":"Schneider Electric GBX0800800704F Planetary Gearbox, 80:1","metaDescription":"Schneider Electric GBX0800800704F planetary gearbox, 80:1 ratio, 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/1a14c761e8a7ff6e032ab64b01c3687a.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0800800704F/gearbox-with-straight-teeth-gbx-ø-80-mm-reduction-801-16arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0800800704F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX0800800704F?","answer":"The continuous output torque is 120 N.m at 100 rpm and 30°C, with a maximum intermittent rating of 192 N.m for peak loads within the 30000-hour service life."},{"question":"What does the 16 arc.min backlash mean for positioning accuracy?","answer":"The 16 arc.min maximum backlash is the lost motion when the output shaft reverses direction — for a bidirectional indexing axis this appears as a dead band the controller must compensate for, or the mechanical system must preload against, to maintain position repeatability."},{"question":"What is the noise level of GBX0800800704F?","answer":"The noise level is 60 dB measured at 1 meter under no-load conditions — this is the acoustic emission from the straight-tooth planetary mesh, not the motor or driven load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0800800704F","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/GBX0800800704F when reusing this data.
