It carries a 16:1 reduction ratio and is rated for 260 N·m continuous output torque, so the unit is sized for mid-range motion axes where the holding and accelerating torque on the load stays inside that envelope; the 416 N·m maximum output torque is the short-duration ceiling a designer must respect for peak accelerations. ## Ratings that drive the fit decision Efficiency is listed at 94 %, which is the figure to fold into the motor-sizing calculation — the gearbox itself consumes roughly 6 % of the input power as heat, so the upstream servo or drive has to be rated to deliver torque at the gearbox input shaft that is 1/16 of the output shaft requirement divided by 0.94. Torsional rigidity is 13 N·m/arcmin and maximum torsional backlash is 12 arc.min — these two numbers together govern positioning accuracy on the driven axis; higher rigidity tightens the closed-loop response, while the backlash figure sets the worst-case reversal error that has to be compensated in the controller. The moment of inertia at the input is 1.75 g·cm², a small value that keeps the reflected inertia on the motor shaft low and avoids dragging down acceleration on a directly coupled servo. ## Service life and the load envelope around the output shaft The published service life is 30000 h at 100 rpm and 30 °C — that envelope is the baseline a designer has to honour when sizing the radial and axial loads on the output shaft, and the published maximum radial force Fr of 1500 N at 100 rpm over 30000 h at 30 °C (rising to 2000 N for a 10000 h life) is keyed to the load being applied at mid-distance from the output shaft. The corresponding maximum axial force Fa is 2100 N at 100 rpm across the 30000 h life, or 2800 N if the service life is limited to 10000 h — these are the figures a mechanical designer uses to size the bearing stack on the driven end and to decide whether an external thrust bearing is needed. Mounting position is unrestricted (any position), which removes the orientation constraint when integrating the unit into a machine, and the IP54 rating at the shaft output covers splash and dust ingress on the seal interface but not direct washdown.","metaTitle":"Schneider Electric GBX1200160842D Planetary Gearbox, 16:1","metaDescription":"Schneider GBX1200160842D GBX-series planetary gearbox, 16:1 reduction, 260 N·m continuous torque, 94 % efficiency.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1200160842D","Efficiency":"94 %","Noise level":"65 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 120 mm- reduction 16:1- < 12arcmin- 260 N.m","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"16:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"1.75 g.cm²","Mounting position":"Any position","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"416 N.m","Service life in hours":"30000 h at 100 rpm at 30 °C","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N at 100 rpm, during 30000 hour at 30°C 2800 N at 100 rpm, during 10000 hour at 30°C","IP degree of protection":"Shaft output: IP54","Maximum radial force Fr":"1500 N at 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N at 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"260 N.m","Gearbox external diameter":"120 mm","Product or component type":"Planetary gearbox","Maximum torsional backlash":"12 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/387a0b65d83f67e77257bfc517ce4fcc.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200160842D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-161-12arcmin-260-n-m/"},"ai":{"faq":[{"question":"What efficiency is published for the GBX1200160842D?","answer":"Efficiency is listed at 94 %, which is the figure to fold into motor-sizing calculations — roughly 6 % of input power is lost as heat inside the gearbox across the 16:1 reduction."},{"question":"What is the noise level of the GBX1200160842D?","answer":"The published noise level is 65 dB measured at 1 m under no-load; once the gearbox carries torque the radiated sound typically rises, so this figure is best read as a baseline rather than a worst case."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200160842D","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/GBX1200160842D when reusing this data.
