Continuous output torque sits at 700 N.m — meaning the gearbox can hold that figure as a steady duty rating, with the 1120 N.m ceiling reserved for transient peaks; sizing the driven machine to the continuous figure keeps the gear teeth out of the wear zone the catalogue otherwise warns about over the 30000 h service life. ## Efficiency, backlash, and the noise floor Efficiency is 94 %, backlash no worse than 10 arc.min, and the housing emits 70 dB(A) measured at 1 m under no-load — the combination is what lets the gearbox hold positioning tolerance on a servo-driven axis without sounding like a mill on the floor. The shaft is C 45 medium-carbon steel running through a black anodised aluminium housing in any mounting position; the moment of inertia at the input is 5.81 g·cm², so the gearbox adds negligible reflected inertia to the servo loop on a typical 160-frame drive package. ## Shaft loads, lubrication, and service-life envelope Maximum radial force on the output shaft is 4200 N at 100 rpm applied at mid-distance over the 30000 h rating at 30 °C, rising to 6000 N if the design target is only 10000 h — the catalogue derates shaft load as a function of both speed and hours, so overdesigning the service-life budget buys headroom on Fr; maximum axial force is 6000 N under the 30000 h / 100 rpm condition and 8000 N under the 10000 h condition on the same envelope. The unit is lubricated for life and sealed to IP54 at the shaft output, runs from -25 °C to 90 °C ambient, and is torsionally rigid at 41 N.m/arcmin — meaning no re-greasing interval lands on the maintenance schedule and the shaft seal holds off splash and dust in a typical industrial cell, not full washdown.","metaTitle":"Schneider Electric GBX1600251081D planetary gearbox, 25:1","metaDescription":"GBX1600251081D — Schneider Electric GBX planetary gearbox, 25:1 reduction, 1120 N.m peak / 700 N.m continuous.
