It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent rating of 416 N.m at the same speed and temperature. Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no field re-greasing interval to schedule. ## Torque, backlash, and stiffness — what the numbers mean for the application The 260 N.m continuous rating is the thermal limit at 100 rpm; the 416 N.m maximum output torque covers acceleration peaks and occasional overloads, but sustained operation above the continuous figure shortens the 30,000-hour service life. Maximum torsional backlash is 12 arcmin — this is a standard-precision planetary, not a zero-backlash stage. If the load reverses direction under position control, the 12 arcmin lash shows up as lost motion at the output. Torsional rigidity is 13 N.m/arcmin — the gearbox twists 1 arcmin for every 13 N.m of applied torque. This stiffness figure governs the wind-up under load and matters when the driven mechanism has its own compliance. Efficiency is 94 % at rated load — the 6 % loss shows up as heat in the housing. The black anodised aluminium body dissipates it, but the ambient temperature range of -25 to 90 °C sets the thermal envelope. ## Shaft loads and sealing — mounting constraints Maximum radial force Fr is 1500 N at 100 rpm for the 30,000-hour life, applied at mid-span on the output shaft. For shorter duty (10,000 hours), the limit rises to 2000 N at the same speed and load point. Maximum axial force Fa is 2100 N at 100 rpm for 30,000 hours, or 2800 N for 10,000 hours. Exceeding these loads pushes the output bearing past its L10 life. Shaft output protection is IP54 — the seal keeps out dust and splashing water at the output shaft, but the gearbox body itself is not sealed. Mount it where the housing stays dry. The output shaft is C45 carbon steel, and the housing is black anodised aluminium. The 120 mm body diameter fits standard mounting flanges in the GBX family. ## Lifecycle — obsolete, sourced through independent channels Available through independent surplus and broker channels.","metaTitle":"Schneider Electric GBX1200120702F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX1200120702F planetary gearbox, 12:1 reduction, 260 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":"12:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Compatibility code":"GBX","Torsional rigidity":"13 N.m/arcmin","Maximum output torque":"3681.9 lbf.in (416 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":"2301.2 lbf.in (260 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/8c9e51ce39ae6814b28d44c16cddbbbb.pdf","sourceUrl":"https://www.se.com/nz/en/product/GBX1200120702F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-121-12arcmin-260-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200120702F/alternatives.json"},"ai":{"faq":[{"question":"What are the continuous and maximum torque ratings for the GBX1200120702F?","answer":"Continuous output torque is 260 N.m at 100 rpm and 30 °C.
