A single source line on the spec sheet still lists as current, but the formal productStatus on the same record is Obsolete — the obsolete reading is the one a procurement line should act on when filling a BOM position. ## What 32:1 actually buys you in this gearbox The 32:1 reduction ratio is paired with a continuous output torque of 260 N.m and a maximum output torque of 416 N.m, so the gearbox is sized for drives that need meaningful torque multiplication without stepping up to a larger 120 mm-plus housing class. Maximum torsional backlash is listed at 12 arc.min, which puts the unit in the standard backlash band for a precision planetary stage rather than the low-backlash tier — fine for general motion and conveyor service, but a buyer targeting high-precision indexing should note this figure before specifying. Efficiency is rated at 94 %, meaning roughly 6 % of the input power is dissipated as heat through the gear stage; useful when calculating thermal budget at the gearbox housing during continuous duty. The straight-tooth construction (Gear box type Straight teeth) keeps the noise floor at 65 dB at 1 m under no-load, which is a useful baseline for enclosure acoustics in panel-room or machine-side installations. ## Shaft loads and service-life envelope Shaft output carries IP54 sealing, so the gearbox tolerates dust and light splash at the shaft exit but is not rated for washdown or high-pressure cleaning — keep that in mind for food-line or outdoor mounting. Maximum radial force Fr is 1500 N at 100 rpm over a 30000 h service life and rises to 2000 N if the duty is derated to 10000 h, with the load applied at mid-distance from the output shaft — the radial envelope scales with how long the gearbox is expected to run. Maximum axial force Fa follows the same service-life curve: 2100 N over 30000 h at 100 rpm, climbing to 2800 N over 10000 h, with the operating ambient capped at 30 °C for those figures. Moment of inertia is 1.3 g.cm² and torsional rigidity is 13 N.m/arcmin, which together describe how the gearbox reacts to fast acceleration steps on the driven shaft. ## Mechanical envelope and where it mounts The gearbox housing is black anodized aluminium with a 120 mm external diameter and a C 45 steel output shaft, and the unit is lubricated for life so no oil-change access has to be designed into the machine layout. Mounting position is rated for any position, which removes a constraint panel-builders often hit with oil-lubricated units, and the operating ambient window runs from -25 °C to 90 °C — a wider envelope than many servo-class gearheads at this OD. ## Sourcing posture for an obsolete line With the productStatus flagged Obsolete and no L-record successor on file, GBX1200320702D is sourced through independent distribution against a buyer RFQ — each quote is lot-specific, with quantities, condition, and traceability confirmed at the time of order.","metaTitle":"GBX1200320702D Schneider planetary gearbox, 32:1, 260 N.m","metaDescription":"Schneider Electric GBX1200320702D planetary gearbox, 32:1 reduction, 260 N.m continuous / 416 N.m peak, 120 mm OD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB at 1 m, no-load","Gear box type":"Straight teeth","Housing colour":"Black","Shaft material":"C 45","Reduction ratio":"32:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"1.3 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/52222a4ca91922f2c7c15c07d5f562fb.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200320702D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-321-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200320702D/alternatives.json"},"ai":{"faq":[{"question":"What are the efficiency and noise figures on this GBX series gearbox?","answer":"Efficiency is rated at 94 % and noise level is 65 dB at 1 m under no-load conditions, both taken from the gearbox's own spec record for the GBX1200320702D variant."},{"question":"What is the closest in-family alternative to GBX1200320702D?","answer":"No official L-record successor is on file for this code, so there is no manufacturer-named pin-compatible replacement to point at; any alternative should be cross-checked against the GBX compatibility code, the 120 mm OD, and the 12 arc.min backlash ceiling before being specified."},{"question":"What is the rated torque envelope for GBX1200320702D?","answer":"Continuous output torque is 260 N.m and maximum output torque is 416 N.m, which together define the working and peak torque bands for sizing the drive upstream of the gearbox."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200320702D","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/GBX1200320702D when reusing this data.
