It delivers 230 N.m continuous output torque at 100 rpm and 30 °C ambient, and can handle 368 N.m peak at the same speed and temperature — the peak figure is for intermittent duty, not sustained running. ## Efficiency, noise, and backlash — the mechanical trade-offs Straight-cut teeth give 94 % efficiency, which is typical for this gear type, but the noise floor sits at 65 dB measured 1 m away under no-load conditions — about the level of a quiet office printer. The 12 arc.min maximum torsional backlash means the output shaft can lag the input by up to 12 minutes of arc before the teeth re-engage; for positioning applications this sets the repeatability floor. Torsional rigidity is 13 N.m/arcmin, so under a 230 N.m load the shaft wind-up is roughly 17.7 arcmin. ## Mounting and environmental constraints The black anodized aluminium housing is 120 mm in diameter and carries a shaft output IP54 rating — protected against dust ingress and splashing water at the output seal, but not submersible. The C 45 steel shaft handles 2100 N axial force (thrust) and 1500 N radial force (overhung load) for the full 30,000-hour life at 100 rpm; higher loads are possible for shorter durations (2800 N axial, 2000 N radial for 10,000 hours). The gearbox is lubricated for life — no oil-change port or regreasing schedule. Operating ambient spans -25 to 90 °C.","metaTitle":"Schneider Electric GBX1200250702F planetary gearbox, 25:1","metaDescription":"Schneider Electric GBX1200250702F planetary gearbox, 120 mm diameter, 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/5c56dc87143d686568b3a4288629cb74.pdf","sourceUrl":"https://www.se.com/uk/en/product/GBX1200250702F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-251-12arcmin-230-n-m/","alternativesUrl":"https://aoctrl.com/api/mcp/products/GBX1200250702F/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200250702F","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/GBX1200250702F when reusing this data.
