It delivers 15 N.m continuous output torque and can handle 24 N.m peak — the continuous figure is the one to size against for a servo axis that runs cycles all shift. Efficiency is 96 %, so about 4 % of the input power dissipates as heat inside the housing. At 15 N.m output and 100 rpm that is roughly 6 W of thermal loss — well within the aluminium housing's natural convection capacity at 30 °C ambient. ## Backlash and torsional windup — positioning error budget Maximum torsional backlash is 30 arcmin — that is the lost motion at the output shaft when the input reverses direction. For a pick-and-place axis with a 10:1 effective ratio after the belt, 30 arcmin at the gearbox translates to roughly 0.5 mm of positioning uncertainty at the load; budget it into the controller's backlash compensation or accept it as a deadband. Torsional rigidity is 1 N.m/arcmin — the shaft winds up 1 arcmin for every N.m of applied torque. At the 15 N.m continuous rating the windup is 15 arcmin, which adds to the backlash figure for the total angular error under load. ## 30,000-hour service life — bearing and gear fatigue limits Rated service life is 30,000 hours at 100 rpm output speed and 30 °C ambient. At that operating point the maximum radial force on the output shaft is 160 N (applied mid-shaft), and the maximum axial force is 160 N. Run it at higher speed or temperature and the life derates — the 10,000-hour figures allow 200 N radial and 200 N axial. The gearbox is lubricated for life — no oil changes or regreasing intervals. Shaft output seal is IP54, so it keeps out dust and light splash but is not rated for washdown. ## Mounting and integration — any position, 40 mm bore Mounts in any position — horizontal, vertical, or inverted — with no oil migration concern because the lubrication is a lifetime grease charge. The 40 mm outer diameter and C 45 steel output shaft suit direct coupling to a servo motor with a matching pilot diameter. Noise at no-load is 55 dB at 1 m — about the level of a quiet office printer, so it will not dominate the acoustic profile of a machine cell.","metaTitle":"Schneider Electric GBX0400040403D Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX0400040403D planetary gearbox, 4:1 reduction, 15 N.m continuous torque, 96% efficiency, 30 arcmin backlash.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX0400040403D","Efficiency":"96 %","Noise level":"55 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 40 mm- reduction 4:1- < 30arcmin- 15 N.m","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6ebf59363ee395ca205a5f397d495a63.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX0400040403D/gearbox-with-straight-teeth-gbx-ø-40-mm-reduction-41-30arcmin-15-n-m/"},"ai":{"faq":[{"question":"Where can I buy GBX0400040403D and get a price?","answer":"This part is quoted to order through independent distribution."},{"question":"What is the continuous torque rating of GBX0400040403D?","answer":"Continuous output torque is 15 N.m, with a peak of 24 N.m.
