Continuous output torque is 120 N.m at 100 rpm and 30 °C ambient; the peak (maximum output torque) hits 192 N.m under the same conditions, giving roughly 60 % overload headroom for starting or transient loads. Rated service life is 30,000 hours at 100 rpm and 30 °C — the axial and radial force ratings (Fa 2100 N, Fr 1500 N) are also quoted at that life target. Push the duty cycle or ambient temperature and the life drops; the 10,000-hour ratings (Fa 2800 N, Fr 2000 N) show the trade-off. ## What the 94 % efficiency means on the line At 94 % efficiency, the gearbox loses about 6 % of the input power as heat. For a 120 N.m continuous output at 100 rpm (~1.26 kW mechanical), that's roughly 75 W dissipated inside the housing — well within the capacity of the black anodized aluminium body, but worth factoring into the thermal budget if the gearbox is enclosed in a sealed cabinet. The shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion or high-pressure washdown. The rest of the housing is sealed by the anodized aluminium; the lubricated-for-life grease is captive, so no maintenance access ports to leak. ## Sourcing this obsolete planetary gearbox Schneider Electric lists the GBX1200080551F as obsolete. The part is lubricated for life and sealed — no field rebuild path — so replacement is a straight swap of the same unit or a parametric cross. Sourced through independent distribution against an RFQ. No stock-holding claim — every order is quoted to the BOM line.","metaTitle":"Schneider Electric GBX1200080551F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1200080551F planetary gearbox, 8:1 reduction, 120 N.m continuous torque, 94% efficiency, 8 arc.min backlash, IP54.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"Efficiency":"94 %","Noise level":"65 dB 1 m, no-load","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"8:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"1699.3 lbf.in (192 N.m) 100 rpm 86 °F (30 °C)","Nbr. of units in pkg.":"1","Service life in hours":"30000 h 100 rpm 86 °F (30 °C)","Additional information":"Lubricated for life","Maximum axial force Fa":"2100 N 100 rpm, during 30000 hour at 30°C 2800 N 100 rpm, during 10000 hour at 30°C","IP Degree of Protection":"Shaft output IP54","Maximum radial force Fr":"1500 N 100 rpm, force applied at mid-distance from output shaft during 30000 hour at 30 °C 2000 N 100 rpm, force applied at mid-distance from output shaft during 10000 hour at 30 °C","Continuous output torque":"1062.09 lbf.in (120 N.m) 100 rpm 86 °F (30 °C)","Gearbox external diameter":"4.7 in (120 mm)","Product or Component Type":"Planetary gearbox","Maximum torsional backlash":"8 arc.min","Ambient Temperature For Operation":"-13...194 °F (-25...90 °C)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/8ead94bbd8de7a3911f4e71f22c89c27.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200080551F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-81-8arcmin-120-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200080551F/alternatives.json"},"ai":{"faq":[{"question":"What is the GBX1200080551F's continuous torque rating and backlash?","answer":"Continuous output torque is 120 N.m at 100 rpm and 30 °C.
