16:1 planetary in a 60 mm frame
The GBX0600160584D is a straight-tooth planetary gearbox from Schneider Electric's GBX series, sized for servo and stepper motor applications that need a 16:1 reduction in a compact 60 mm diameter housing. Continuous output torque is 44 N.m, with a maximum of 70 N.m for peak loads — enough for indexing, positioning, and light-to-medium conveyor drives without oversizing the frame.
Torque, backlash, and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no re-greasing schedule to track in a sealed motion axis. Maximum torsional backlash is 25 arc.min — standard precision for positioning where the load doesn't reverse direction under torque; for bidirectional positioning, a lower-backlash variant would be the call. Torsional rigidity is 2.5 N.m/arcmin, which tells you how much wind-up you get under load — useful when tuning the servo loop for a stiff axis.
Efficiency, noise, and mounting flexibility
94 % efficiency means only 6 % of the input power is lost as heat — straight-tooth planetary gears are inherently efficient, and this number holds across the torque range. Noise level is 58 dB at 1 m, no-load — quiet enough for a packaging machine or a lab-stage axis without an acoustic enclosure.
