Continuous output torque is 120 N.m at 100 rpm, with a maximum intermittent torque of 192 N.m — enough for indexing tables, small conveyors, or pick-and-place axes that need a compact, low-backlash drive. Efficiency sits at 94 %, and the gearbox is lubricated for life — no oil changes, no maintenance schedule beyond the 30,000-hour service life at rated load. Shaft output carries an IP54 rating, so it handles dust and splash in a cabinet or on a machine frame, but it's not washdown-rated — keep it out of direct spray. ## Backlash, forces, and what limits your application Maximum torsional backlash is 14 arc.min — that's standard precision for a straight-tooth planetary, not a zero-backlash stage. If your axis reverses load and needs better than 14 arc.min repeatability, this gearbox will show hysteresis. Maximum radial force on the output shaft is 650 N at mid-span for the full 30,000-hour life, or 950 N if you accept a 10,000-hour service interval. Axial force (Fa) is capped at 900 N for 30,000 hours, 1200 N for 10,000 hours. Torsional rigidity is 6.5 N.m/arcmin — a stiff enough shaft for most servo-driven positioning, but the 14 arc.min backlash is the limiting factor for precision dwell. Noise level is 60 dB at 1 m, no-load — quiet enough for a lab or assembly line, but a belt or chain drive running at the same load will be louder. ## Lifecycle reality — obsolete, sourced through surplus Schneider Electric lists the GBX0800121404F as obsolete. The housing is black anodized aluminium, shaft material is C45 steel — standard construction that means any replacement will need to match the 80 mm body diameter and the 12:1 ratio to fit your existing mount. Because it's obsolete, availability runs through independent surplus and broker channels. We source each unit against a confirmed RFQ — quantities and pricing confirmed at quote time. No stock-holding claim; every order is a procurement event.","metaTitle":"Schneider Electric GBX0800121404F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0800121404F planetary gearbox, 12:1 reduction, 120 N.m continuous torque, 94% efficiency, IP54.
