Continuous output torque is 155 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 248 N.m under the same conditions. That 155 N.m continuous figure is the one to size against — the motor-side input torque multiplied by the ratio and efficiency determines whether the gearbox lives its full 30,000-hour service life. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this ratio. The 6 % loss goes into heat inside the housing — the black anodized aluminium body dissipates it, but in a confined panel or enclosed drive train, the ambient temperature must stay within the -25 to 90 °C operating range. ## Shaft loading limits and backlash — the mechanical interface constraints Maximum radial force on the output shaft is 1500 N at 100 rpm for the full 30,000-hour life, applied at mid-distance from the shaft face. Axial force is capped at 2100 N under the same duty. Exceed these and the bearing life drops faster than the torque derating curve suggests — the 2800 N / 10000-hour axial rating is the short-term ceiling. Torsional backlash is 8 arc-minutes maximum, with a torsional rigidity of 12 N.m/arcmin. For a positioning axis that needs repeatable direction reversal, that 8 arc-min of lost motion at the output means the encoder or load-side feedback must account for the windup before the gear train engages. The shaft output seal is rated IP54 — splash protection from the shaft side, but the gearbox body itself is not sealed for washdown. The housing is black anodized aluminium; the shaft is C45 steel. Lubrication is factory-filled for life, so no maintenance oil changes are needed. ## Obsolete — sourcing through independent channels Schneider Electric lists this gearbox as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical direct replacement has been announced by Schneider.","metaTitle":"Schneider Electric GBX1200040554F Planetary Gearbox, 4:1","metaDescription":"Schneider Electric GBX1200040554F planetary gearbox, 4:1 ratio, 155 N.m continuous torque, 94% efficiency.","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/505ed072352d08918297404a3800c5c3.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200040554F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-41-8arcmin-155-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200040554F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of GBX1200040554F?","answer":"Continuous output torque is 155 N.m at 100 rpm and 30 °C.
