It delivers a continuous output torque of 120 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N.m under the same conditions. Rated efficiency sits at 94 %, and the unit is lubricated for life — no periodic oil changes. Service life is specified at 30,000 hours at rated torque and speed, provided the ambient temperature stays within -25 to 90 °C. ## Torque, backlash, and shaft loading limits Torsional backlash is held below 14 arc.min — adequate for positioning axes where the load reversal is infrequent or the downstream encoder closes the loop. Torsional rigidity is 6.5 N.m/arcmin, which means the wind-up under continuous torque is about 18.5 arcmin at 120 N.m. Maximum radial force on the output shaft is 650 N at mid-span, rated for the full 30,000-hour service life at 100 rpm. Axial force is capped at 900 N for the same duty. The shaft is C45 steel; the housing is black anodised aluminium with an IP54 rating at the shaft output — suitable for dry indoor environments but not washdown. Noise level is 60 dB at 1 m, no-load — typical for a straight-tooth planetary of this size. The straight-tooth profile is less efficient than helical under load but delivers lower cost and simpler back-driving characteristics. ## Sourcing an obsolete planetary gearbox Schneider Electric lists the GBX0800121401F as obsolete. The unit is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ.","metaTitle":"Schneider Electric GBX0800121401F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX0800121401F planetary gearbox, 12:1 reduction, 120 N.m continuous torque, 94% efficiency.
