9:1 planetary stage for a 160 mm servo footprint
The GBX1600091083D sits at the low end of the GBX planetary family as a 9:1 single-stage unit — a 160 mm frame, straight-cut gearing, and a C45 output shaft sized for direct coupling to a servo or stepper in a packaging line, indexing table, or pick-and-place axis where one reduction ratio is enough and an extra stage would just add inertia. Mechanical efficiency is rated 94% — for a single planetary stage that lands in the expected band, meaning roughly 6% of input power leaves as heat; on a continuous-duty conveyor drive that waste shows up as housing temperature rise, so the gearbox's -25...90 °C ambient envelope and lubricated-for-life fill have to carry the thermal budget without scheduled re-greasing.
Backlash and rigidity — where this gearbox actually fits
Backlash is specified at 10 arc-min maximum and torsional rigidity at 41 N·m/arcmin, which places the GBX1600091083D firmly in the standard-precision class rather than the low-backlash tier; pick-and-place, screw-down, and indexing conveyor applications tolerate that play, but a high-end CNC feed axis or registration cut-off usually needs a tighter figure before it will close the loop cleanly. Acoustic output is 70 dB measured at 1 m on the no-load bench, so the housing will be audible above a quiet cell background; in a noisy press shop it disappears, but a standalone machine in an open area may want a noise enclosure or an elastomeric coupling to take the edge off the gear mesh harmonics.
Shaft loads tied to the 30000 h duty rating
Maximum axial load Fa is 6000 N at 100 rpm over the 30000 h service-life envelope, or 8000 N if the application is only rated for 10000 h, and radial load Fr scales the same way — 4200 N at 30000 h and 6000 N at 10000 h, both referenced to the mid-span of the output shaft at 30 °C; the dual rating is the way the catalogue lets a buyer trade bearing life against applied load without leaving the same gearbox family. Mounting position is unrestricted, so the unit drops onto a machine in any orientation, and the shaft seal carries IP54 — splash- and dust-resistant rather than washdown-rated, meaning the GBX1600091083D belongs in a dry cabinet or a sheltered area, not directly under a food-and-bev hose-down station.
