Schneider Electric's own record lists the GBX1600081382D as obsolete, so a fresh factory allocation is no longer the route — independent surplus and broker channels are where this gearbox moves, and lead times track lot availability rather than a production schedule. The datasheet field still reads \"current\" alongside the obsolete flag, which is the kind of split a buyer should reconcile with the manufacturer's PCN/EOL notice before locking a multi-year BOM. ## What 720 N.m peak and 6 arc.min backlash actually mean on this gearbox The GBX1600081382D is rated for a maximum output torque of 720 N.m with a continuous output torque of 450 N.m — peak for acceleration and shock loads, continuous for thermal sizing of the driven machine. Torsional rigidity of 38 N.m/arcmin is the twist per radian under load; pair it with the maximum torsional backlash of 6 arc.min and you have a gearbox whose positioning error budget is dominated by the backlash figure on reversible servo applications, not the elastic twist. Reduction ratio 8:1 and straight-cut gears keep the unit simple and cost-effective — backlash lands at 6 arc.min rather than the sub-arcmin a helical or planetary-with-preload unit would offer, but the efficiency holds at 96 % at the listed duty and the acoustic signature is a flat 70 dB at 1 m, no-load. ## Service life, load curves, and the 100 rpm window Schneider rates the gearbox for 30 000 h at 100 rpm and 30 °C — that is the reference operating window against which the axial and radial load curves are published. Above 100 rpm or above 30 °C ambient the L10 horizon shortens; below it the envelope extends. The shaft is lubricated for life, so the buyer does not schedule a grease interval — only a mechanical-condition check at overhaul. Maximum axial force Fa is 6000 N at 100 rpm over the full 30 000 h service envelope, rising to 8000 N at 100 rpm if the duty is capped at 10 000 h. Maximum radial force Fr at mid-distance from the output shaft is 4200 N over 30 000 h and 6000 N over 10 000 h at 100 rpm. These are the numbers that constrain the pulley, pinion or coupling selection on the output side. ## Environment, mounting, and the 160 mm frame The shaft output carries an IP54 seal — splash- and dust-resistant but not washdown-rated; deploy it inside a cabinet or on a sheltered section of the line rather than at the wet end. Operating envelope is −25…90 °C and the gearbox mounts in any attitude, so the unit fits on a vertical slide, an inverted mount, or a horizontal reducer pad without changing the lubrication regime. Mechanical build is a C 45 steel shaft in a black anodized aluminium housing with a 160 mm external gearbox diameter. Moment of inertia at the input is 4.63 g.cm² — small enough that the gearbox does not dominate the servo loop's inertia ratio when paired with the typical mid-frame Lexium or similar servo in this 160 mm class.","metaTitle":"Schneider GBX1600081382D Planetary Gearbox, 8:1, 720 N.m","metaDescription":"Schneider Electric GBX1600081382D planetary gearbox, 8:1 reduction, 720 N.m peak / 450 N.m continuous, IP54 shaft seal, 30 000 h service life.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"96 %","Noise level":"70 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"4.63 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"38 N.m/arcmin","Maximum output torque":"720 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"6000 N at 100 rpm, during 30000 hour at 30°C 8000 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"4200 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 6000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"450 N.m","Gearbox external diameter":"160 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"6 arc.min","Ambient Temperature For Operation":"-25...90 °C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/6188f04131063699e9a2db6f6903013d.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600081382D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-81-6arcmin-450-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1600081382D/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy GBX1600081382D and what does a quote look like?","answer":"No factory allocation is on offer because the part is obsolete; condition, quantity, and lead time are confirmed against the specific lot at quote time rather than from a stock counter."},{"question":"What is GBX1600081382D's listed efficiency and noise level?","answer":"Efficiency is 96 % at the rated duty, and noise is 70 dB measured at 1 m on a no-load run.
