Form factor and what lands in the panel
The Schneider Electric GBX1600091385D is a planetary gearbox from the GBX series with a 160 mm external diameter, black anodized aluminium housing, and a C 45 steel output shaft (cites:,). It mounts in any position, so the bracketry decides the orientation rather than the gearbox itself (cites:). The shaft seal carries an IP54 rating — splash-proof rather than washdown-rated, which sets the enclosure environment this unit belongs in (cites:). Lubrication is factory-filled for life, so the unit arrives sealed and stays sealed across its service interval (cites:).
Reduction, efficiency, and what the buyer is sizing
At 9:1 reduction with 94 % mechanical efficiency, the GBX1600091385D steps down servo or motor output while keeping drive losses modest — the missing 6 % shows up as heat and is the reason the housing is anodized aluminium for thermal dissipation (cites:,). Maximum torsional backlash is 10 arc.min and torsional rigidity is 41 N·m/arcmin, so the gearbox is engineered for motion-control duties where positioning repeatability matters more than raw ratio range (cites:,). No-load noise is rated 70 dB at 1 m — typical for an industrial planetary stage and quiet enough for cells where an operator stands within arm's reach (cites:).
Service life, radial and axial load envelope
Service life is 30000 h at 100 rpm and 30 °C ambient — the published duty cycle a buyer sizes a maintenance interval against (cites:). The operating envelope runs from -25 °C to 90 °C, so cabinet-side thermal management rarely constrains indoor machinery rooms (cites:). Maximum radial force at the output shaft is 4200 N over the full 30000 h service life (6000 N if the duty is de-rated to 10000 h), and maximum axial force is 6000 N over the same 30000 h envelope — these figures are applied at mid-distance from the output shaft and govern how a pulley, pinion, or coupling is sized onto the output (cites:,).
Lifecycle status and the procurement reality
Schneider Electric marks this MPN as obsolete, so the BOM line moves to last-time-buy or independent-channel sourcing rather than factory-direct reorder (cites:,).
