Efficiency is listed at 94 %, which is typical for a single-stage planetary stage at this ratio. That 6 % loss shows up as heat in the gear mesh; the black anodized aluminium housing sinks it, and the lubricated-for-life grease charge handles the thermal load within the -25 to 90 °C operating envelope. Torsional backlash is 9 arc.min maximum — this is a standard-precision grade, not a zero-backlash unit. For a pick-and-place or indexing application where reversal accuracy matters, that 9 arc.min of lost motion at the output adds up to about 0.15 mm of positioning error at a 100 mm radius arm. If the application needs tighter positioning, a preloaded or low-backlash stage is the next step up. ## Load ratings — axial, radial, and service life The output shaft, in C45 steel, carries a maximum axial force of 1200 N for a 10000-hour life at 30 °C and 100 rpm, dropping to 900 N if you want the full 30000-hour design life. Radial force at mid-span on the output shaft is 950 N for 10000 hours or 650 N for 30000 hours. These are the bearing limits — exceed them and the gearbox wears out before the 30000-hour mark. Service life is rated at 30000 hours at 100 rpm and 30 °C with continuous rated torque. That's about 3.4 years of 24/7 operation at nameplate conditions. The IP54 rating on the shaft output means it keeps dust and splashing water out of the seal area — fine for a dry indoor conveyor line, but not for washdown environments. Torsional rigidity is 6 N.m/arcmin — the gearbox wind-up under load. At the continuous torque of 85 N.m, that's about 14 arcmin of elastic twist in the gear train, on top of the 9 arcmin of backlash. For open-loop speed control this is irrelevant; for a servo axis with a load-side encoder, the controller can compensate for the wind-up. ## Obsolete — sourcing through independent channels Schneider Electric lists the GBX0800030554F as obsolete. The GBX series has been superseded by newer planetary gearbox families with different frame dimensions and mounting interfaces — a direct drop-in replacement is unlikely without mechanical adaptation. No stock-holding claim — each lot is verified for condition and runtime before it ships. The 94 % efficiency, 85 N.m continuous torque, and 3:1 ratio are the three numbers that confirm fit against the original specification. If the application can tolerate a different frame size or mounting pattern, a current-production planetary gearbox from the same power class is the more sustainable choice.","metaTitle":"Schneider Electric GBX0800030554F Planetary Gearbox, 3:1","metaDescription":"Schneider Electric GBX0800030554F planetary gearbox, 80 mm, 3:1 ratio, 85 N.m continuous torque, 94% efficiency.
