Efficiency is listed at 94 % and the housing is black anodized aluminium around a C45 shaft, so the box is built to live on a machine frame, not in a cabinet — the IP54 rating applies at the shaft output, which keeps splash and dust off the seal where it actually matters. ## Torque envelope and shaft loading Continuous output torque is rated at 800 N.m and the maximum output torque is 1280 N.m, meaning the gearbox will hold steady-state load at the lower figure and absorb peaks roughly 60 % higher before the rating gives way. Maximum radial force Fr on the output shaft is 4200 N at 100 rpm over a 30000 h life at 30 °C, climbing to 6000 N if the duty is capped at 10000 h; maximum axial force Fa is 6000 N over the same 30000 h envelope and 8000 N over the shorter 10000 h envelope — the hour rating decides the load the shaft will take, not the headline force number. Service life is quoted at 30000 h at 100 rpm at 30 °C, and the gearbox ships lubricated for life, so the MRO planner is not opening it up for grease on the scheduled route. ## Precision, stiffness, and the operating envelope Maximum torsional backlash is 10 arc.min and torsional rigidity is 41 N.m/arcmin — enough stiffness for point-to-point motion on a packaging or indexing axis where a sloppy reducer shows up as a lag in the servo loop. Moment of inertia at the input is 12.37 g.cm², which keeps the reflected load back to the servo drive low; ambient operating range is -25...90 °C and the box mounts in any position, so the cable dress on the machine is what picks the orientation, not the gearbox. Noise level is 70 dB at 1 m under no-load, which is the figure to compare against an enclosure or line-side noise survey when the gearbox lands inside a workstation. ## Sourcing posture — active production, quoted per BOM For MRO and project-build quantities the gearbox is sourced through independent distribution and quoted to order against the RFQ, with current price and lead time confirmed at quote time; no figure is published here.","metaTitle":"Schneider Electric GBX1600121084D Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX1600121084D planetary gearbox, Ø160 mm, 12:1 reduction, 800 N.m continuous / 1280 N.m peak, IP54 shaft, active.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600121084D","Efficiency":"94 %","Noise level":"70 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 160 mm- reduction 12:1- < 10arcmin- 800 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"12:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"12.37 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"41 N.m/arcmin","Maximum output torque":"1280 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":"800 N.m","Gearbox external diameter":"160 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"10 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/b08ccd78bd4048247bf5cda91c15183e.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1600121084D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-121-10arcmin-800-n-m/"},"ai":{"faq":[{"question":"What is GBX1600121084D's listed efficiency on this Gear Reducers & Gearboxes line?","answer":"Efficiency is listed at 94 % for the GBX1600121084D — that is the mechanical efficiency of the planetary reduction at its rated operating point."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1600121084D","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/GBX1600121084D when reusing this data.
