Obsolete — sourced through surplus channels
Schneider Electric has marked the GBX0400161002F as obsolete. No official successor or replacement part number is listed by the manufacturer. This planetary gearbox is available through independent surplus and broker channels. Quantities are confirmed at RFQ — no stock-holding claim is made here.
16:1 planetary reduction, 20 N.m continuous
The GBX0400161002F is a 40 mm diameter planetary gearbox with straight-cut teeth and a 16:1 reduction ratio. It delivers 20 N.m continuous output torque at 100 rpm and 30 °C, with a maximum intermittent torque of 32 N.m under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, and the unit is lubricated for life — no maintenance oil changes are needed in the field. Efficiency is listed at 94 %, which is typical for a single-stage planetary set at this ratio. Torsional backlash is 28 arcmin maximum — this is a standard-precision gearbox, not a zero-backlash servo unit.
Mounting and environmental limits
The housing is black anodized aluminium, shaft material is C45 steel. The output shaft carries an IP54 rating — protected against dust ingress and splashing water, but not for washdown or submerged service. Maximum axial and radial forces at the output shaft are 200 N each when derated for 10,000-hour life at 100 rpm, dropping to 160 N for the full 30,000-hour rating. Noise level is 55 dB at 1 m under no-load conditions — quiet enough for a cabinet-mounted index drive or light conveyor application without additional acoustic enclosure.
