It delivers a continuous output torque of 6 N.m (53.1 lbf.in) at 100 rpm and 30 °C, with a maximum intermittent torque of 10 N.m (88.5 lbf.in) under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C — the lubrication is sealed for life, so no maintenance interval for grease changes. The housing is black anodized aluminium; the output shaft is C45 steel. ## Torque, backlash, and load ratings Continuous torque (6 N.m) is the figure for sizing in steady-state applications. The maximum output torque of 10 N.m covers occasional peak loads — for example, during acceleration or momentary overload — but sustained operation above 6 N.m shortens the service life. Maximum torsional backlash is 30 arc-minutes. That is a standard-precision grade for a planetary stage of this size — adequate for positioning where the load does not reverse frequently or where the downstream mechanism absorbs the lost motion. Radial and axial load limits are 200 N at 100 rpm for a 10,000-hour life, derated to 160 N for the full 30,000-hour rating. The radial force is specified at the midpoint of the output shaft. Ambient operating range is -25 to 90 °C. Torsional rigidity is 1 N.m/arcmin — the stiffness of the gear train under load. Efficiency is 94 %, meaning about 6 % of input power is lost as heat in the gear mesh and bearings. ## Obsolete — sourced through independent channels Schneider Electric lists the GBX0400081003F as obsolete. The part is available through independent surplus and broker distribution — quantities are confirmed at RFQ, and the price reflects the lot availability at the time of inquiry. The shaft output seal is rated IP54 — suitable for dry indoor environments with dust and splash exposure, but not for washdown or submersion. The gearbox is lubricated for life and requires no field service.","metaTitle":"Schneider Electric GBX0400081003F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX0400081003F planetary gearbox, 40 mm diameter, 8:1 reduction, 6 N.m continuous torque, 94% efficiency.
