It delivers 700 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 1120 N.m under the same speed and temperature conditions. Torsional backlash is rated at 10 arc.min maximum — this sets the positioning repeatability floor for the driven axis. The torsional rigidity of 41 N.m/arcmin means the gearbox winds up about 0.024° under full continuous load, which matters for servo or indexing applications where cumulative error stacks across multiple stages. ## 94 % efficiency, 30000 h service life, lubricated for life Efficiency is listed at 94 % — roughly 6 % of input power is lost as heat inside the gearbox. For a 700 N.m output at 100 rpm (about 7.3 kW mechanical), that's roughly 440 W of thermal dissipation that the black anodized aluminium housing must sink to ambient. The operating range is -25 to 90 °C ambient, so forced ventilation or a larger mounting surface may be needed if the duty cycle is high in a warm enclosure. Service life is 30000 hours at 100 rpm and 30 °C ambient running at rated torque — that's about 3.4 years of continuous operation. The gearbox is lubricated for life, so no oil-change interval or breather port to maintain. Noise output is 70 dB at 1 m under no-load conditions — typical for a straight-tooth planetary of this size; helical or ground-tooth versions would run quieter but are a different product line. ## Shaft loading limits — axial and radial force budgets Maximum axial force Fa is 6000 N for the full 30000-hour service life at 100 rpm, or 8000 N if the application only needs 10000 hours. Radial force Fr at mid-span on the output shaft is 4200 N for 30000 hours, 6000 N for 10000 hours. These are the bearing life limits — exceeding them shortens service life faster than torque overload does. The output shaft is C 45 medium-carbon steel, and the shaft output seal is rated IP54 — splash-resistant but not submersible. The housing is black anodized aluminium, 160 mm diameter. Mounting dimensions and input flange pattern are standard for the GBX series; the gearbox is supplied as a single unit. ## Obsolete — sourcing through independent channels Schneider Electric has marked the GBX1600400552F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ time. For a BOM that needs this exact reduction ratio, torque class, and 160 mm frame size, the GBX1600400552F is the only direct fit. A replacement would require re-engineering the mounting interface, input adapter, and output coupling.","metaTitle":"Schneider Electric GBX1600400552F planetary gearbox, 40:1","metaDescription":"Schneider Electric GBX1600400552F planetary gearbox, 160 mm, 40:1 reduction, 700 N.m continuous torque, 94 % efficiency, 10 arc.min backlash.","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":"40:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"41 N.m/arcmin","Maximum output torque":"9912.8 lbf.in (1120 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":"6195.5 lbf.in (700 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":"10 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/69c072ac403ad388382763f9a22f8a30.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600400552F/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-401-10arcmin-700-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1600400552F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600400552F","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/GBX1600400552F when reusing this data.
