160 mm planetary gearbox — torque and ratio
The GBX1600151382D: This is a straight-tooth planetary gearbox from the GBX series, 160 mm housing diameter, with a 15:1 reduction ratio. Continuous output torque is 700 N.m, with a maximum of 1120 N.m for peak loads — the continuous figure is the one to size against for steady-state conveyor or rotary-table duty. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this size. Noise level is 70 dB at 1 m, no-load — expect a few dB higher under full torque.
Load ratings and service life at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient. At that speed, maximum axial force (Fa) is 6000 N and maximum radial force (Fr) is 4200 N applied at mid-shaft. If you need 8000 N axial or 6000 N radial, the life drops to 10,000 hours at the same speed and temperature. Torsional rigidity is 41 N.m/arcmin, and maximum torsional backlash is 10 arc.min — this is a standard-precision gearbox, not a zero-backlash servo unit. Moment of inertia is 12.35 g.cm², which matters for acceleration/deceleration calculations on servo or stepper-driven axes.
Obsolete — sourcing through independent channels
Schneider Electric lists this gearbox as obsolete. The housing is black anodized aluminium, shaft material is C 45 steel. Shaft output seal is IP54 — suitable for dry indoor environments but not washdown. Lubricated for life, so no oil-change interval to track.
