Its continuous output torque is 120 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N.m under the same conditions — the margin between continuous and peak tells you how much overload the gear train can absorb before the service-life clock starts ticking faster. The 94 % efficiency figure is the power-transmission efficiency at rated load; the remaining 6 % becomes heat in the gear mesh, so the housing (black anodised aluminium) acts as the heat sink. For a servo or stepper application, that efficiency holds across most of the speed range, but the torque derating above 30 °C ambient follows the lubricant viscosity curve — the box is lubricated for life, so there is no oil-change interval to extend the thermal budget. ## Backlash, rigidity, and the load-reaction envelope Maximum torsional backlash is 8 arc.min — that is the angular play at the output shaft when the input is locked. For indexing or positioning axes, this figure sets the repeatability floor; a 120 mm output flange with 8 arc.min backlash translates to roughly 0.14 mm of tangential play at a 100 mm radius. Torsional rigidity is 12 N.m/arcmin, meaning the shaft wind-up under 120 N.m continuous load is about 10 arcmin of elastic deflection on top of the backlash. The shaft output seal is rated IP54 — splash-proof but not washdown-rated. Maximum axial force (Fa) is 2100 N for the full 30,000-hour service life at 100 rpm and 30 °C, or 2800 N if you accept a 10,000-hour life. Radial force (Fr) applied at mid-span on the output shaft is 1500 N for 30,000 hours or 2000 N for 10,000 hours. These are the bearing-life limits; exceeding them reduces service life non-linearly. Noise level is 65 dB at 1 m, no-load — a straight-tooth planetary is inherently noisier than a helical, but the 65 dB figure is measured without load; under torque the mesh noise rises slightly due to tooth deflection. The C 45 shaft material is induction-hardenable, which matters if the output shaft sees keyway stress or press-fit loads from the driven pulley or coupling. ## Obsolete — sourcing the GBX1200080554F through independent channels Schneider Electric has marked the GBX1200080554F as obsolete. The part is sourced through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. Availability and current pricing are established at quote time against the BOM quantity. For a contract-manufacturing buyer with a customer AVL that lists this exact MPN, a deviation notice may be required if the customer's approved vendor list does not allow substitution. The GBX series shares a common 120 mm flange pattern and 8:1 ratio with other GBX variants, but the straight-tooth gear set and 8 arc.min backlash are specific to this order code — verify the mating motor shaft and pilot diameter against the customer's assembly drawing before committing.","metaTitle":"Schneider Electric GBX1200080554F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1200080554F planetary gearbox, 8:1 reduction, 120 N.m continuous torque, 94% efficiency.
