Planetary gearbox for precision motion — 15:1 reduction, 18 N.m continuous
The GBX0400151002F is a 40 mm planetary gearbox from Schneider Electric with a 15:1 reduction ratio and a continuous output torque of 18 N.m at 100 rpm and 30 °C. Rated efficiency is 94 %, and the noise level at 1 m under no-load is 55 dB — both figures that matter when the gearbox runs in a quiet production environment or on a conveyor line where energy loss adds up over a shift.
Load ratings and service life — what the numbers mean for fit
The continuous torque rating (18 N.m) is the steady-state limit; the maximum output torque reaches 29 N.m under the same conditions, giving a short-term overload margin for acceleration or momentary jams. Service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for grease changes, which simplifies MRO planning on a line that runs multiple shifts. Maximum axial and radial forces on the output shaft are both 200 N for a 10,000-hour life target, dropping to 160 N for the full 30,000-hour service life — these limits govern the overhung load from a belt drive or the thrust from a lead screw.
