Continuous output torque is 230 N.m at 100 rpm and 30 °C; the maximum allowable torque before mechanical damage is 368 N.m under the same conditions. The 230 N.m figure is the thermal and mechanical endurance limit for 30,000-hour service life — the 368 N.m ceiling is for occasional peak loads, not sustained duty. Efficiency is 94 % at rated load, meaning 6 % of the input power is lost as heat inside the housing. For a 1 kW input, roughly 60 W must be dissipated through the black anodized aluminium body — no external cooling is needed at this power level, but the housing surface temperature will rise above ambient by the thermal resistance of the aluminium-to-air interface. ## Obsolete — sourcing reality for the GBX1200250701F Available through independent surplus and broker channels. No pin-compatible or form-fit-function replacement is documented by Schneider, so a substitution would require a full mechanical re-evaluation of the mounting interface, shaft dimensions, and keyway. ## Mechanical limits — axial and radial loads on the output shaft Maximum axial force Fa is 2100 N at 100 rpm for the full 30,000-hour service life, or 2800 N if the application accepts a reduced 10,000-hour life. Maximum radial force Fr is 1500 N at 100 rpm for 30,000 hours, or 2000 N for 10,000 hours — both measured at the mid-point of the output shaft. These limits govern overhung loads from pulleys, sprockets, or direct-coupled loads. Exceeding the radial force shortens bearing life faster than exceeding the axial force, because the radial load vector acts directly on the output bearing race. ## Backlash, noise, and environmental ratings Maximum torsional backlash is 12 arc-minutes — the angular play between input and output when the direction reverses. For positioning applications that need better than 0.2° repeatability, a lower-backlash gearbox (e.g. 3–5 arc-min) would be required. Noise level is 65 dB at 1 m under no-load conditions — roughly the sound of a quiet office printer. Under load the noise rises with torque and speed; the straight-tooth geometry generates more whine than helical gears at the same power level. Shaft output protection is IP54 — dust-protected and splash-resistant at the rotating seal, but not submersible. The housing itself is sealed; the IP rating applies only to the output shaft interface, not the motor input flange. The C45 steel output shaft and black anodized aluminium housing resist corrosion in indoor industrial environments but are not rated for outdoor or washdown exposure beyond the IP54 boundary.","metaTitle":"Schneider Electric GBX1200250701F Planetary Gearbox, 25:1","metaDescription":"Schneider Electric GBX1200250701F planetary gearbox, 25:1 reduction, 230 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":"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/7f680d1ad547e37674b869b21892825d.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200250701F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-251-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200250701F/alternatives.json"},"ai":{"faq":[{"question":"What is the continuous torque rating of the GBX1200250701F?","answer":"Continuous output torque is 230 N.m at 100 rpm and 30 °C, with a maximum allowable torque of 368 N.m for occasional peak loads.
