What this planetary gearbox delivers
The GBX0400150554F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for applications requiring a 15:1 reduction ratio in a 40 mm diameter package. It delivers 18 N.m continuous output torque at 100 rpm, with a maximum intermittent torque of 29 N.m under the same conditions. Efficiency is rated at 94 %, with a no-load noise level of 55 dB measured at 1 m — figures that matter when the gearbox runs continuously in a production line and every percentage point of loss shows up as heat or energy cost. The housing is black anodized aluminium with shaft output protection rated IP54, and the C 45 steel output shaft is specified for radial and axial loads up to 200 N (at 100 rpm, 10,000-hour life) or 160 N (at 30,000-hour life), with the radial force applied at mid-distance on the shaft.
Mechanical constraints and integration
Maximum torsional backlash is 28 arc.min — this is a standard-precision planetary, not a zero-backlash stage. If your axis reverses direction under load, the lost motion at the output will be at least this value before the gear train picks up. Service life is declared at 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life — no oil-change interval to schedule, but the rating assumes the load stays within the continuous torque envelope. Operating ambient range is -25 to 90 °C. Torsional rigidity is 1.1 N.m/arcmin, which gives a stiffness figure for calculating windup under peak load. For a 15:1 reduction, the reflected inertia at the motor shaft will be the load inertia divided by 225, minus the gearbox's own inertia contribution.
Lifecycle status and sourcing
