Torque and backlash — the fit for precision positioning
The GBX1600160704F is a 160 mm planetary gearbox with a 16:1 reduction ratio, delivering 800 N.m continuous output torque at 100 rpm and 30 °C ambient. Maximum torque reaches 1280 N.m under the same conditions, giving a 1.6× overload margin for transient peaks during acceleration or reversing. Maximum torsional backlash is 10 arc.min — this sets the repeatability floor for indexing or positioning axes. Torsional rigidity of 41 N.m/arcmin means the gearbox resists wind-up under load; a 410 N.m step deflects the output by about 10 arcmin before the load sees full torque.
Load ratings and service life — sizing the bearing set
Rated service life is 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance interval for oil changes. The output shaft carries a maximum axial force (Fa) of 6000 N and a maximum radial force (Fr) of 4200 N over the full 30,000-hour life, both measured at 100 rpm with the radial load applied at mid-shaft. For shorter duty cycles (10,000 hours), Fa rises to 8000 N and Fr to 6000 N. The shaft output seal is rated IP54, so the gearbox handles dust and splash exposure but is not washdown-rated. Ambient operating range is -25 to 90 °C, which covers most indoor industrial enclosures without derating.
Lifecycle reality — obsolete, sourced through independent channels
Schneider Electric lists the GBX1600160704F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. Efficiency is 94 % at rated load, and noise level measures 70 dB at 1 m under no-load conditions — both figures assume the gearbox is mounted on a rigid base with proper alignment to the motor and load.
