That ratio is the headline number for a speed-reduction spec: an input of 8000 rpm delivers 100 rpm at the output shaft, multiplying torque by roughly the ratio minus efficiency losses. Continuous output torque is 260 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 416 N.m under the same conditions. For a motion axis driving a constant load — conveyor, indexing table, rotary actuator — the continuous figure governs thermal steady-state; the maximum figure covers acceleration and emergency stops within the 30000-hour service life. Efficiency is listed at 94 %, which is typical for a single-stage planetary with straight teeth. The 6 % loss shows up as heat in the lubricant; the gearbox is lubricated for life, so no maintenance interval for oil changes applies. ## Mechanical interface — shaft loads, backlash, and environmental sealing The output shaft is C45 steel, and the housing is black anodized aluminium. Maximum radial force Fr is 1500 N at 100 rpm for the 30000-hour life, applied at mid-distance on the output shaft; axial force Fa is 2100 N under the same duty. These are the limits for belt-pulley or chain-sprocket overhung loads — exceeding them shortens bearing life faster than the torque rating. Torsional backlash is maximum 14 arc-minutes, and torsional rigidity is 12 N.m/arcmin. For a positioning axis that reverses direction, the 14 arc-minutes of lost motion must be accounted for in the servo tuning or compensated in the controller; a lower-backlash gearbox would be needed for high-precision indexing. The shaft output seal carries an IP54 rating — protection against dust ingress and splashing water, but not immersion or high-pressure washdown. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not freezer or oven applications without derating. ## Lifecycle status — obsolete, sourced through independent channels Schneider Electric lists this gearbox as obsolete. Sourcing runs through independent distribution — quantities are confirmed at RFQ against the BOM line, and the landed cost includes the premium for a discontinued part with no direct drop-in replacement. The 94 % efficiency, 80:1 ratio, and 120 mm frame size define the mechanical envelope. If a replacement is needed, the search should match these three parameters plus the output shaft diameter and keyway dimensions — a parametric cross-reference, not a pin-compatible swap.","metaTitle":"Schneider Electric GBX1200800551F Planetary Gearbox, 80:1","metaDescription":"Schneider Electric GBX1200800551F planetary gearbox, 80:1 ratio, 260 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":"65 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":"12 N.m/arcmin","Maximum output torque":"3681.9 lbf.in (416 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":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"2301.2 lbf.in (260 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"14 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/22abc75ced747061437f047169acc7b2.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200800551F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-801-14arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200800551F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX1200800551F?","answer":"Continuous output torque is 260 N.m at 100 rpm and 30 °C.
