Continuous output torque is 450 N.m at 100 rpm (30 °C ambient), with a maximum peak of 720 N.m for transient overloads — the sustained rating is what governs the duty cycle on a conveyor or indexing table. Efficiency is 94 %, meaning 6 % of input power is lost as heat through the gear mesh; for a 5 kW motor input that's 300 W of thermal load the housing must sink. ## Stiffness, backlash, and overhung load limits Torsional rigidity is 38 N.m/arcmin — the shaft twists 1 arcminute for every 38 N.m of applied torque, which sets the windup error in a positioning system. Maximum torsional backlash is 6 arc.min, the angular play between input and output when reversing direction; this is the figure a motion-control engineer uses to budget lost motion in the mechanical train. Maximum axial force on the output shaft is 6000 N at 100 rpm for the 30000-hour service life, or 8000 N for a 10000-hour life — the lower figure is the conservative design-in value. Maximum radial force is 4200 N at 100 rpm for 30000 hours, rising to 6000 N for 10000 hours, both measured at the midpoint of the output shaft — belt-drive or chain-sprocket loads must stay within these limits to avoid bearing fatigue. ## Service life, sealing, and maintenance Rated service life is 30000 hours at 100 rpm and 30 °C ambient — about 3.4 years of continuous operation at that speed before the gearset reaches its wear limit. The gearbox is lubricated for life, so no oil-change intervals or breather maintenance are required; the sealed charge covers the gear mesh for the full service life. Shaft output sealing is IP54, meaning dust-protected and splash-resistant at the output seal — suitable for indoor industrial environments but not washdown or submerged service. ## Sourcing reality — obsolete, sourced to order Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. The 94 % efficiency, 8:1 ratio, and 450 N.m continuous torque are the specs that confirm fit against the BOM line — verify the input flange pattern and output shaft dimensions against the mating motor and load before committing.","metaTitle":"Schneider Electric GBX1600080703F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1600080703F planetary gearbox, 8:1 ratio, 450 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":"70 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"38 N.m/arcmin","Maximum output torque":"6372.5 lbf.in (720 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":"6000 N 100 rpm, during 30000 hour at 30°C 8000 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"4200 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 6000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"3982.8 lbf.in (450 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"6.3 in (160 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"6 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/cc4f26a4e515ae76e4fb982b898fd25d.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1600080703F/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-81-6arcmin-450-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1600080703F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600080703F","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/GBX1600080703F when reusing this data.
