Continuous output torque is 230 N.m at 100 rpm and 30 °C; maximum intermittent torque reaches 368 N.m under the same conditions — the margin between continuous and peak tells you this unit handles moderate overloads without immediate derating, provided the duty cycle stays short. Maximum torsional backlash is 12 arc.min — that is the angular play at the output shaft when the input is locked. For positioning axes that reverse direction, this backlash value sets the repeatability floor; if the application needs tighter than 12 arc.min, this gearbox introduces a dead band the controller must manage or compensate. ## Load ratings and bearing life at 100 rpm Rated service life is 30,000 hours at 100 rpm and 30 °C — that is about 3.4 years of continuous run time before bearing or gear wear reaches the end-of-life criterion. The gearbox is lubricated for life, so no oil changes are scheduled; the sealed IP54 shaft output keeps contaminants out of the bearing cavity as long as the shaft seal is intact. Maximum radial force Fr is 1500 N at 100 rpm for the 30,000-hour target, applied at mid-distance on the output shaft. Axial force Fa is 2100 N under the same duty. If the application needs 2800 N axial or 2000 N radial, the bearing life drops to 10,000 hours — plan the replacement interval accordingly. The C 45 shaft material is standard medium-carbon steel; it handles these loads without surface hardening provided the force application point stays within the shaft shoulder. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX1200250554F as obsolete. Available through independent surplus and new-old-stock channels. No pin-compatible or footprint-equivalent alternative is documented by Schneider, so a substitution requires checking the mounting flange, shaft diameter, and keyway dimensions against the existing installation.","metaTitle":"Schneider Electric GBX1200250554F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1200250554F planetary gearbox, 120 mm diameter, 25:1 reduction, 230 N.m continuous torque at 100 rpm.","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":"25:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"3257.07 lbf.in (368 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":"2035.7 lbf.in (230 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":"12 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/7c52d3535f41765db3a22fced2210650.pdf","sourceUrl":"https://www.se.com/us/en/product/GBX1200250554F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-251-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200250554F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous output torque of the GBX1200250554F at 100 rpm?","answer":"Continuous output torque is 230 N.m at 100 rpm and 30 °C.
