It delivers 120 N.m continuous output torque and peaks at 192 N.m at 100 rpm, 30 °C ambient — the number that governs continuous duty is the 120 N.m figure; the peak is for intermittent overloads within the 30000-hour service life. Torsional rigidity is 12 N.m/arcmin, and maximum backlash is 8 arcmin. For a positioning axis, the 8 arcmin is the lost motion at reversal — if your application needs better than that, you back-drive through a preloaded gearbox or a different tooth profile. ## Torque, life, and thermal limits — the numbers that set the duty cycle Continuous torque is 120 N.m at 100 rpm, 30 °C. Maximum output torque is 192 N.m at the same speed and temperature — that is the ceiling before the gear teeth yield, not a continuous rating. Service life is 30000 hours at the continuous torque figure; push it to the maximum and the life drops to 10000 hours. The axial and radial force limits at 100 rpm are 2100 N axial (30000 h) and 1500 N radial (mid-span, 30000 h). At 10000-hour life those go to 2800 N axial and 2000 N radial. If your load overhangs the shaft, the radial force at the bearing is higher than the mid-span figure — account for the lever arm. Efficiency is 96 % — typical for a single-stage planetary. The 4 % loss is mostly gear mesh friction and bearing drag; at 120 N.m and 100 rpm that is about 50 W of heat to dissipate through the aluminium housing. ## Mounting, materials, and maintenance — panel wireman notes Housing is black anodized aluminium, shaft is C45 steel. Mounting position is any — the gearbox is lubricated for life, so no breather orientation or oil-level check. The 120 mm diameter body and keyed output shaft mate to standard flange patterns in the GBX family; the input coupling is sized for the motor shaft diameter on the driving side.","metaTitle":"Schneider Electric GBX1200081401F Planetary Gearbox, 8:1","metaDescription":"Schneider Electric GBX1200081401F planetary gearbox, 8:1 reduction, 120 N.m continuous torque, 96% efficiency, IP54, active production.
