Maximum output torque reaches 184 N.m under the same conditions, giving a 1.6× overload margin for transient loads. Torsional rigidity is 12 N.m/arcmin, and maximum backlash is 8 arc.min — these figures govern positioning accuracy in indexing or servo-driven applications where lost motion must be bounded. ## Efficiency, noise, and service life Rated efficiency is 94 % — the remaining 6 % is lost as heat in the gear mesh and bearings, so the thermal balance at continuous rated torque keeps the housing within the -25 to 90 °C ambient window. Noise level is 65 dB at 1 m, no-load, which is low enough for most machine-tool and material-handling environments without additional enclosure treatment. Service life is 30,000 hours at 100 rpm and 30 °C; the gearbox is lubricated for life, so no periodic oil changes are needed. ## Sourcing and lifecycle — obsolete, quoted to order Schneider Electric lists the GBX1200031001F as obsolete. For a line-down or MRO situation, the 120 mm diameter and 3:1 ratio define the envelope and speed match — any replacement must fit the same mounting footprint and output torque class. ## Mechanical integration and load limits The housing is black anodized aluminium, 120 mm external diameter, with a C 45 steel output shaft. Shaft output seal is rated IP54 — suitable for dry indoor environments but not washdown. Maximum axial force on the output shaft is 2100 N for 30,000-hour life at 100 rpm, or 2800 N for 10,000-hour life. Maximum radial force (applied at mid-distance from the output shaft) is 1500 N for 30,000-hour life, or 2000 N for 10,000-hour life. These limits are interdependent with speed and temperature — exceeding them shortens bearing life faster than the torque derating alone.","metaTitle":"Schneider Electric GBX1200031001F Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX1200031001F planetary gearbox, 3:1 ratio, 115 N.m continuous torque, 94% efficiency.
