Continuous output torque is rated at 400 N.m and the peak sits at 640 N.m; against a 96 % efficiency figure, the gearbox itself burns roughly 4 % of the input power as heat, so at full continuous load the thermal margin is dominated by the case-to-mounting-surface path rather than by internal gear friction. Service life is published at 30,000 h at 100 rpm and 30 °C — the published load ratings below are derated for that life; running hot or fast shortens the window on the same bearing and gear set. ## Backlash, rigidity and the load the shaft can take Maximum torsional backlash is 6 arc.min and torsional rigidity is 38 N.m/arcmin, so a positioning application sees roughly 0.16° of wind-up at the continuous torque rating — small enough for most servo point-to-point moves, but worth checking against the application's accuracy budget. The moment of inertia reflected back to the input is 12.14 g.cm², which keeps the gearbox from dominating the drive's acceleration loop in mid-size servo pairings; combined with 70 dB at 1 m no-load the unit is quiet enough for indoor cells without acoustic enclosure. Shaft loading is split into two regimes: up to 6000 N axial and 4200 N radial at 100 rpm for the published 30,000 h life, rising to 8000 N axial and 6000 N radial if the application is sized for only 10,000 h — the lower-force numbers are the ones to design against for long-duty installations like conveyors and palletisers. ## Sealing, environment and where it physically bolts in IP54 at the shaft output seals against splashing water and dust but not against high-pressure washdown, so the GBX1600031084D suits general factory floors and machine interiors rather than food-grade or outdoor cabinets; ambient operating range is -25 to 90 °C. The housing is black anodized aluminium with a C 45 steel output shaft, lubricated for life — no grease fittings to schedule in the maintenance plan, but a confirmed service interval on the application side rather than a mid-life regrease. Mounting position is unrestricted, so the gearbox can be oriented to suit the machine layout; the matching servo coupling and the GBX-series adapter kit are what line up to the drive, not the gearbox itself.","metaTitle":"Schneider GBX1600031084D planetary gearbox, 3:1, 400 N.m","metaDescription":"Schneider Electric GBX1600031084D planetary gearbox, 160 mm, 3:1 reduction, 400 N.m continuous, 96 % efficient, IP54 shaft seal.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600031084D","Efficiency":"96 %","Noise level":"70 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 160 mm- reduction 3:1- < 6arcmin- 400 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"3:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"12.14 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"38 N.m/arcmin","Maximum output torque":"640 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":"400 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/366cb1a8dbc44c6e11650eddef16667d.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600031084D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-31-6arcmin-400-n-m/"},"ai":{"faq":[{"question":"What is the listed efficiency of GBX1600031084D?","answer":"The datasheet figures 96 % mechanical efficiency for the GBX1600031084D, so roughly 4 % of the input power is converted to heat inside the gearbox rather than delivered to the output shaft."},{"question":"How loud is GBX1600031084D at the output shaft?","answer":"Noise level is published at 70 dB measured at 1 m under no-load — comfortable for a general factory floor and quiet enough that no acoustic enclosure is required at the gearbox itself."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600031084D","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/GBX1600031084D when reusing this data.
