The GBX family is sold on a 12 arc.min maximum backlash figure, so it is positioned for positioning axes where repeatable return-to-position matters more than the headline ratio. Continuous output torque is rated 260 N.m, with a 416 N.m peak ceiling for accelerating or shock-loaded duty, and the design life is sized for 30000 h at 100 rpm at 30 °C — the duty envelope an integrator should size against, not the peak number on the brochure. ## Shaft load envelope and bearings Maximum radial load on the output shaft is 1500 N at 100 rpm over the full 30000 h service life (2000 N if the application only needs 10000 h), and the maximum axial load is 2100 N under the same envelope (2800 N at the shorter life rating), force applied at mid-distance from the output shaft. The values are derated together — an integrator running higher than 100 rpm must pull both the Fa and Fr curves off the datasheet before sizing the coupling. Moment of inertia at the input is 1.3 g.cm², which keeps reflected inertia low for small-frame servo motors; the output shaft is C 45 medium-carbon steel, and the housing is black anodized aluminium — lightweight enough for moving carriages without giving up the heat-sinking a continuous-duty gearbox needs. ## Precision, stiffness, and operating envelope Torsional rigidity is 13 N.m/arcmin and maximum torsional backlash is 12 arc.min — paired numbers an automation engineer reads together: the gearbox will wind up under load by a predictable amount, but the unloaded return-to-position is repeatable enough for indexing and pick-and-place. Mounting position is unrestricted (any position), so the unit can be oriented to suit the machine envelope rather than the other way round. Operating ambient temperature spans -25 °C to 90 °C, and efficiency is rated 94 % on this size — meaning most of the motor power reaches the load and the gearbox does not need an external cooler inside the rated envelope. Noise is 65 dB measured at 1 m with the unit running no-load, the figure an integrator uses for cabinet-noise budgeting rather than the loaded operating figure. ## Sealing, lubrication, and on-machine integration The shaft seal carries an IP54 rating at the output, which covers dust ingress and splashing water but is not a washdown rating — an integrator specifying it for food-and-beverage lines or outdoor equipment should treat that as a placement constraint and add guarding. Lubrication is filled for life, so the unit ships ready to mount with no scheduled grease interval inside the 30000 h service window at 100 rpm / 30 °C.","metaTitle":"GBX1200320703D Schneider Electric Planetary Gearbox, 32:1","metaDescription":"Schneider Electric GBX1200320703D planetary gearbox, 32:1 reduction, 260 N.m continuous / 416 N.m peak, Ø 120 mm.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1200320703D","Efficiency":"94 %","Noise level":"65 dB at 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 120 mm- reduction 32:1- < 12arcmin- 260 N.m","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/01d9af59755a65c37fcfea88faf8dca7.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1200320703D/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-321-12arcmin-260-n-m/"},"ai":{"faq":[{"question":"How do I get current pricing and availability for GBX1200320703D?","answer":"Pricing and availability are confirmed at quote time through independent industrial distribution — submit the BOM line and quantity against an RFQ and the order will be quoted against current channel stock and lead time.
