Rated for 120 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 192 N.m at the same speed — the peak figure handles acceleration and emergency stops, but the continuous rating governs sustained duty. Efficiency is 94 % at rated load — about 6 % of input power is lost as heat in the gear mesh and bearings, which matters for thermal management in a confined enclosure. ## Backlash, stiffness, and service life — the precision specs Maximum torsional backlash is 14 arc.min — this is the lost motion at the output shaft when reversing direction, a key parameter for positioning accuracy in pick-and-place or rotary indexing applications. For comparison, precision-grade planetary gearboxes typically run 5–10 arc.min; this sits at the standard commercial level. Torsional rigidity is 6.5 N.m/arcmin — the shaft twist under load. Stiffer gearboxes (higher N.m/arcmin) maintain better position holding under varying torque. Service life is rated at 30000 hours at 100 rpm and 30 °C ambient — roughly 3.4 years of continuous operation. The gearbox is lubricated for life, so no maintenance interval for oil changes. ## Load limits — axial and radial force ratings Maximum axial force (Fa) on the output shaft is 1200 N for a 10000-hour life at 30 °C, dropping to 900 N for the full 30000-hour rating — overhung pulley or sprocket loads must stay within these limits to avoid bearing fatigue. Maximum radial force (Fr) applied at mid-distance on the output shaft is 950 N for 10000-hour life, or 650 N for 30000-hour life — radial loads from belt drives or direct-coupled loads need to be checked against the lower figure for the rated service life. ## Environmental and mechanical construction Shaft output sealing is IP54 — protected against dust ingress and splashing water, suitable for indoor industrial environments but not washdown or outdoor exposure. Housing is black anodized aluminium; shaft material is C45 medium-carbon steel. Ambient operating range is -25 to 90 °C. Noise level is 60 dB at 1 m, no-load — comparable to a quiet office environment; actual noise under load will be higher depending on the motor and coupling.","metaTitle":"Schneider Electric GBX0800120704F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0800120704F planetary gearbox, 80 mm, 12:1 ratio, 120 N.m continuous torque, 94% efficiency.
