Continuous output torque is 155 N.m at 100 rpm and 30 °C; the maximum short-term torque hits 248 N.m under the same conditions — that's the overload ceiling before you risk gear damage. Rated service life is 30,000 hours at rated load and speed, and the unit ships lubricated for life — no oil changes, no maintenance schedule on the gearbox itself. ## Backlash, forces, and mounting fit Maximum torsional backlash is 8 arc.min — typical for a precision straight-tooth planetary stage; if your application needs less than 5 arc.min, this gearbox won't hold it without a preload or a different tooth profile. Maximum axial force on the output shaft is 2100 N at 100 rpm for the full 30,000-hour life, or 2800 N if you accept a shorter 10,000-hour window. Radial force limits are 1500 N and 2000 N respectively, measured at mid-span on the shaft. Shaft output carries an IP54 rating — fine for a dry indoor environment but not for washdown or direct spray. The housing is black anodized aluminium; the shaft is C45 steel. ## Sourcing reality — obsolete, but available Schneider Electric lists this part as obsolete. The GBX1200040551F is available through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ against your BOM line.","metaTitle":"Schneider Electric GBX1200040551F planetary gearbox","metaDescription":"Schneider Electric GBX1200040551F planetary gearbox, 4:1 reduction, 155 N.m continuous torque, 94% efficiency, 30,000 h service life.","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":"4:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"12 N.m/arcmin","Maximum output torque":"2195.0 lbf.in (248 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":"1371.9 lbf.in (155 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/74330de35341efe10a4f2cbd762847f4.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200040551F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-41-8arcmin-155-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200040551F/alternatives.json"},"ai":{"faq":[{"question":"How can I order GBX1200040551F or check availability?","answer":"Submit an RFQ with your target quantity."},{"question":"What is the continuous torque rating of GBX1200040551F?","answer":"Continuous output torque is 155 N.m at 100 rpm and 30 °C.
