It delivers 18 N.m continuous output torque and peaks at 29 N.m maximum, with 94 % efficiency across the operating band. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — the lubrication is sealed for life, so no maintenance interval on the oil change. The black anodized aluminium housing carries an IP54 rating at the shaft output, which means it resists dust ingress and splashing water in the coupling area but is not submersible. ## Load ratings and mechanical limits Maximum axial force on the output shaft is 200 N at 100 rpm for a 10,000-hour life, derating to 160 N for the full 30,000-hour target. Radial force follows the same profile — 200 N at mid-shaft for 10,000 hours, 160 N for 30,000 hours. Torsional rigidity is 1.1 N.m/arcmin, and the maximum backlash is 35 arcmin — this is a commercial-grade positioning gearbox, not a zero-backlash precision stage. The moment of inertia reflected to the input is 0.019 g.cm², which is low enough that a small servo or stepper can accelerate the load without a large torque penalty. Mounting position is unrestricted — the gearbox can be installed in any orientation. The C 45 steel output shaft is standard for this torque class. ## Obsolete — sourcing through independent channels Schneider Electric has marked the GBX0400250401D as obsolete. Available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider; a functional equivalent would require verifying the mounting flange, shaft diameter, and input interface against the application.","metaTitle":"Schneider Electric GBX0400250401D Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX0400250401D planetary gearbox, 40 mm diameter, 25:1 reduction, 18 N.m continuous torque, 94% efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","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","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","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"35 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5d6c8dc8aff8c1ce220d219efc5a358c.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400250401D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-251-35arcmin-18-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400250401D/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0400250401D?","answer":"18 N.m continuous output torque, with a maximum intermittent torque of 29 N.m."},{"question":"What is the noise level of this gearbox?","answer":"55 dB at 1 m under no-load conditions — quiet enough for most indoor automation cells without an enclosure."},{"question":"What compliance documentation does Schneider provide for the GBX0400250401D?","answer":"Compliance documentation would need to be verified against the original manufacturing batch or requested from the surplus source."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX0400250401D","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/GBX0400250401D when reusing this data.
