Continuous output torque is 18 N.m at 100 rpm at 30 °C, with a maximum intermittent torque of 29 N.m at the same speed and temperature — the higher figure is for acceleration peaks, not sustained running. Efficiency sits at 94 %, which is typical for a single-stage planetary set with straight teeth; the noise level is 55 dB at 1 m under no-load, quiet enough for a benchtop or lab environment. ## Lifecycle reality — obsolete, sourced to order Sourcing runs through independent surplus and new-old-stock channels; quantities are lot-specific and confirmed at RFQ. ## Mechanical limits that govern the fit Service life is rated 30,000 hours at 100 rpm and 30 °C — if your duty cycle runs the gearbox hotter or faster, derate the life accordingly. The operating ambient range is -25 to 90 °C. Maximum axial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life, dropping to 160 N for the full 30,000-hour rating. Radial force follows the same pattern: 200 N at mid-shaft for 10,000 hours, 160 N for 30,000 hours. Torsional rigidity is 1.1 N.m/arcmin — this tells you how much the output shaft twists under load. For positioning applications, the 28 arcmin maximum backlash means this is not a zero-backlash gearbox; it's built for speed reduction, not precision indexing. Shaft output seal is IP54 — splash-resistant but not submersible. The housing is black anodized aluminium, the shaft is C45 steel. Lubricated for life, so no maintenance oil changes.","metaTitle":"Schneider Electric GBX0400250571G Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX0400250571G planetary gearbox, 25:1 reduction, 18 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":"55 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"25:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.019 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1.1 N.m/arcmin","Maximum output torque":"29 N.m at 100 rpm at 30 °C","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"200 N at 100 rpm, during 10000 hour at 30°C 160 N at 100 rpm, during 30000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"200 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C 160 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C","Continuous output torque":"18 N.m at 100 rpm at 30 °C","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"28 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/80d616663ab377914736343334608215.pdf","sourceUrl":"https://www.se.com/vn/en/product/GBX0400250571G/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-251-28arcmin-18-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400250571G/alternatives.json"},"ai":{"faq":[{"question":"What torque can GBX0400250571G handle continuously?","answer":"Continuous output torque is 18 N.m at 100 rpm at 30 °C.
