160 mm planetary frame, 20:1 reduction
The GBX1600201385D is a Schneider Electric GBX-series planetary gearbox in the 160 mm frame, with straight-cut teeth and a 20:1 reduction ratio. The black anodized aluminium housing carries a C45 steel output shaft, with the gearbox lubricated for life so no field service schedule applies to the gear mesh itself. At the output shaft the continuous rating is 800 N.m and the maximum output torque is 1280 N.m, with a 30000 h service life at 100 rpm and 30 °C ambient.
Radial and axial load the output shaft accepts
With a 20:1 planetary stage the output shaft has to carry the overhung loads from the driven element, so the spec lists both radial and axial limits: 4200 N radial at 100 rpm over the full 30000 h, rising to 6000 N if the duty is limited to 10000 h at 30 °C; axial capacity is 6000 N for the 30000 h window and 8000 N for the 10000 h window at the same 100 rpm and 30 °C. A belt or coupling applied at mid-distance from the shaft face has to be checked against these curves, not against the torque number alone.
Backlash, torsional rigidity, and sealing
Maximum torsional backlash is 10 arc.min and torsional rigidity is 41 N.m/arcmin, with a moment of inertia of 6.64 g·cm² at the input. That places the unit in the standard backlash class for a planetary stage of this diameter — adequate for packaging indexing and conveyor duty where position repeatability is in the arc-minute band, not for high-precision servo applications that demand sub-arc-minute gearing. The shaft output carries an IP54 sealing rating, so the unit is intended for general industrial interiors, not washdown or outdoor exposure where a higher IP class would be required at the shaft seal.
Efficiency and acoustic signature
Mechanical efficiency is rated 94 % and the no-load noise level is 70 dB measured at 1 m. On a packaging line this gives a predictable thermal budget at the gearbox — useful when the reducer is paired with a servo drive whose continuous torque is sized close to the gearbox continuous figure.
Schneider Electric lists the GBX1600201385D as active in the current lifecycle. The GBX series is a long-running planetary line and this 160 mm / 20:1 variant is the diameter-and-ratio combination most often dropped into a packaging-machine or conveyor drivetrain — on the BOM it reads as a qualified part rather than a custom-engineered stage. No stock-holding claim is attached to this listing; the lead-time posture is confirmed at RFQ along with any current-volume pricing.
