Where this GBX sits in a drivetrain
The GBX1600251384D is a planetary gearbox in the Schneider Electric GBX family — a 160 mm frame, 25:1 single-stage reducer with straight-cut gearing, designed to drop between a servo or induction drive and a machine's driven shaft.
Torque and backlash envelope
Peak output torque is 1120 N.m with continuous rating at 700 N.m, and the maximum torsional backlash is 10 arc.min — the figure an integrator watches when a positioning axis must hold under reversing load without lost motion in the gear train. Torsional rigidity of 41 N.m/arcmin tells you how much the shaft will wind up under transient load before the next stage of the drivetrain compensates; under 6 N.m/arcmin of applied twist the unit stays inside the listed backlash band.
Service life and load derating
Service life is 30000 h at 100 rpm and 30 °C — the baseline the buyer derates from when the real duty cycle runs hot, fast, or loaded sideways on the output shaft. Maximum radial force Fr is 4200 N at 100 rpm over 30000 h, rising to 6000 N if the bearing envelope is cut to 10000 h; the comparable axial force Fa ceiling is 6000 N at the long-life rating and 8000 N at the shorter one. These four load numbers (Fr, Fa, lifetime hours, rpm) collectively define the rating envelope — exceeding Fr at higher rpm cuts the service life proportionally even if the torque is well inside the continuous rating.
Mechanical and environmental envelope
Housing is black anodized aluminum with a C 45 shaft, and the shaft seal holds IP54 — the gearbox tolerates a plant washdown or outdoor canopy but is not rated for full submersion or high-pressure jet exposure. Ambient operating temperature is -25 to 90 °C; efficiency is 94 % on the single-stage reduction; noise level is 70 dB at 1 m no-load, which is the figure a sound-sensitive cell (injection-molding cells, clean rooms, lab automation) should compare against its own noise budget.
