Its continuous output torque is 230 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 368 N.m at the same speed — the margin covers acceleration peaks and short overloads without oversizing the gearbox. Rated service life is 30,000 hours at the continuous torque rating and 100 rpm, which translates to roughly 3.4 years of 24/7 operation before the gearset reaches its wear limit. ## Backlash and torsional stiffness for positioning accuracy Maximum torsional backlash is 12 arcmin — this is the lost motion at the output shaft when the input reverses direction, and it sets the repeatability floor for the positioning loop. For a ball-screw-driven axis with a 10 mm lead, 12 arcmin of backlash translates to roughly 0.03 mm of lost travel at the load. Torsional rigidity is 13 N.m/arcmin, meaning the gearbox wind-up under load is predictable and can be compensated in the servo tuning if the application demands sub-arcminute positioning. Efficiency is 94 % at rated load — the 6 % loss appears as heat in the gearset, so the gearbox housing acts as the primary heat sink; no external cooling is needed at the continuous torque rating. ## Shaft loading and environmental limits Maximum axial force on the output shaft is 2100 N for the full 30,000-hour service life at 100 rpm, or 2800 N if the application accepts a 10,000-hour life. Radial force is limited to 1500 N applied at mid-span of the output shaft for the 30,000-hour target. The shaft output seal is rated IP54 — splash-proof but not submersible; the gearbox mounts in any position, which simplifies integration into a crowded machine frame. Ambient operating range is -25 to 90 °C, and the housing is black anodized aluminium with a shaft material of C45 steel — the anodized finish resists corrosion in washdown-adjacent environments but the IP54 shaft seal is the wet-end limit. ## Active production — quoted per BOM No direct pin-compatible replacement exists within the GBX family at the same 40:1 ratio and 120 mm frame size — the part is the current standard offering for this torque class.","metaTitle":"Schneider Electric GBX1200401001F Planetary Gearbox, 40:1","metaDescription":"Schneider Electric GBX1200401001F planetary gearbox, 40:1 ratio, 230 Nm continuous torque, 94% efficiency, 12 arcmin backlash.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Gear Reducers & Gearboxes"],"specifications":{"title":"GBX1200401001F","Category":"18305-MOTION CONTROL CONNECTORS & ACCESS","Efficiency":"94 %","Noise level":"65 dB 1 m, no-load","description":"gearbox with straight teeth GBX- Ø 120 mm- reduction 40:1- < 12arcmin- 230 N.m","Gear box type":"Straight teeth","Housing Colour":"Black","Shaft material":"C 45","Reduction ratio":"40:1","lifecycle_stage":"current","Housing material":"Black anodized aluminium","Device short name":"GBX","Moment Of Inertia":"0.0004 lb.in² (1.3 g.cm²)","Mounting position":"Any position","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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/8d11acac24284cba9b5049fff85d1c46.pdf","sourceUrl":"https://www.se.com/ie/en/product/GBX1200401001F/gearbox-with-straight-teeth-gbx-ø-120-mm-reduction-401-12arcmin-230-n-m/"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/GBX1200401001F","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/GBX1200401001F when reusing this data.
