Reduction ratio is fixed at 12:1 — the gearbox takes the input rpm and divides it by twelve, multiplying torque by the same factor minus losses. With 94% efficiency at rated duty, that loss budget is tight enough for servo sizing work where thermal accounting matters. Lubricated for life and rated for any mounting position, it ships ready to bolt onto a motor face or inline shaft without scheduled grease intervals. ## Torque envelope and backlash — what 1280 N.m actually permits Maximum output torque is 1280 N.m — the peak the gearbox can deliver in transient duty. Continuous output torque is held to 800 N.m, so steady-state loading must be planned against the lower figure or thermal accumulation will shorten bearing life. Maximum torsional backlash is 10 arc.min, paired with 41 N.m/arcmin torsional rigidity — adequate for point-to-point motion but not a precision-cutter choice. For servo applications the 10 arc.min dead-band is the number to work into the loop tuning, not the rated rigidity. Moment of inertia at the input is 12.37 g.cm² — low enough that the gearbox adds negligible reflected load to a mid-sized servo, so acceleration limits remain motor-side rather than gearbox-side. ## Shaft loads vs service life — 30000 hours at 100 rpm Service life is rated at 30000 hours at 100 rpm and 30 °C — the benchmark figure that the load tables are anchored to. Maximum radial force Fr on the output shaft is 4200 N when applied at mid-distance over that 30000-hour life, rising to 6000 N if the duty is capped at 10000 hours. Maximum axial force Fa scales the same way: 6000 N over the full life envelope, 8000 N on the shortened duty. That two-tier table is the one a mechanical designer actually uses: if the application runs slower than 100 rpm or accepts a shorter service window, the shaft can take proportionally more chain or belt pull without bearing fatigue becoming the failure mode. ## Acoustic and thermal envelope for cabinet placement Noise level is 70 dB measured at 1 m under no-load — straight-tooth gearboxes are louder than helical, and this figure tells the cabinet acoustician whether sound enclosure is needed when several units sit close together. The shaft seal is IP54 — protected against dust ingress and water spray, but not rated for hosedown or submerged service.","metaTitle":"Schneider GBX1600121382D planetary gearbox, 12:1, 1280 N.m","metaDescription":"Schneider GBX1600121382D planetary gearbox, straight teeth, 12:1 reduction, 1280 N.m peak, 800 N.m continuous, 94% efficient.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1600121382D","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/c48359caf8947b4bfba7fecaf3eadd1c.pdf","sourceUrl":"https://www.se.com/nl/en/product/GBX1600121382D/gearbox-with-straight-teeth-gbx-ø-160-mm-reduction-121-10arcmin-800-n-m/"},"ai":{"faq":[{"question":"What does the 1280 N.m vs 800 N.m split mean for sizing?","answer":"Peak torque is 1280 N.m and continuous output torque is 800 N.m.
