This ratio is typical for matching a high-speed motor output — servo or stepper — to a lower-speed, higher-torque load such as a conveyor drive, indexing table, or linear actuator. Continuous output torque is 230 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 368 N.m under the same conditions. The 30,000-hour service life at rated load gives a replacement interval for production planning — budget the gearbox change at that mark if the duty cycle stays within the continuous torque envelope. ## Torque, backlash, and force limits — what they mean for the machine Efficiency is listed at 94 %, which means 6 % of the input power dissipates as heat inside the housing. For a 230 N.m continuous output at 100 rpm (roughly 2.4 kW input), the thermal loss is about 150 W — the black anodized aluminium housing sinks that without forced cooling in most panel-mount or machine-frame installations. Maximum torsional backlash is 12 arc.min — this is the angular play between input and output when reversing direction. For positioning applications that need better than 0.2° repeatability, a lower-backlash gearbox (3–5 arc.min) would be needed; for simple speed reduction or non-reversing loads, 12 arc.min is acceptable. Axial force on the output shaft is limited to 2100 N for the full 30,000-hour life, or 2800 N if you accept a shorter 10,000-hour service interval. Radial force — the overhung load from a belt or chain sprocket — is 1500 N at mid-span for 30,000 hours, 2000 N for 10,000 hours. These limits govern the bearing selection on the driven component; a belt drive that exceeds 1500 N radial load will shorten gearbox life. Noise level is 65 dB at 1 m under no-load conditions — this is the acoustic signature from the straight-cut gear mesh. In a quiet production environment (below 70 dB background), the gearbox will be audible; helical or ground-gear stages would run quieter but are not offered in this GBX variant. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX1200251401F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. The gearbox is lubricated for life and sealed at the shaft output to IP54 — no maintenance grease changes are required, but the seal condition should be inspected if the unit has been in long-term storage. Ambient operating range is -25 to 90 °C, covering most indoor industrial environments.","metaTitle":"Schneider Electric GBX1200251401F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1200251401F planetary gearbox, 25:1 ratio, 230 N.m continuous torque, 94% efficiency, IP54 shaft output.","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/2323756fc2fd1efd748f3406b200c115.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200251401F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-251-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200251401F/alternatives.json"},"ai":{"faq":[{"question":"What are the key torque ratings for GBX1200251401F?","answer":"Continuous output torque is 230 N.m at 100 rpm and 30 °C.
