It delivers 15 N.m continuous output torque and peaks at 24 N.m maximum, making it sized for servo or stepper applications in the sub-24 N.m range. The housing is black anodized aluminium; the output shaft is C45 steel. Rated IP54 at the shaft output — the housing seals against dust and splash, but the gearbox is not submersible. ## Torque, life, and the ratings that govern the application Continuous torque is 15 N.m; maximum torque is 24 N.m. The service life is 30,000 hours at 100 rpm and 30 °C ambient — the life rating is tied to the input speed and temperature, not just runtime. At higher speeds or temperatures the service life shortens; the axial and radial force ratings also derate with speed and target life (200 N at 10,000 h vs 160 N at 30,000 h, both at 100 rpm and 30 °C). Efficiency is 96 % — typical for a single-stage planetary with straight teeth and grease lubrication. The noise level at no-load is 55 dB at 1 m, which is quiet enough for a lab or light assembly environment but not silent; the straight-cut teeth produce some gear whine under load. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0400040402D as obsolete. No official successor part number is published in the lifecycle record. The gearbox is sourced through independent surplus and broker channels — quantities are confirmed at RFQ, and the supply is lot-specific. The gearbox is lubricated for life — no maintenance oil changes. Mounting position is any orientation, which simplifies integration into existing machine layouts.","metaTitle":"Schneider Electric GBX0400040402D planetary gearbox, 4:1","metaDescription":"Schneider Electric GBX0400040402D planetary gearbox, 40 mm diameter, 4:1 reduction, 15 N.m continuous torque, 96 % efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","Noise level":"55 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.022 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"1 N.m/arcmin","Maximum output torque":"24 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":"15 N.m","Gearbox external diameter":"40 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"30 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/82577908ab01c2ae8a724d122d4fe676.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX0400040402D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-41-30arcmin-15-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX0400040402D/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX0400040402D?","answer":"15 N.m continuous, with a maximum output torque of 24 N.m.
