16:1 planetary — 260 N.m continuous, 94 % efficiency
The GBX1200161403F is a Schneider Electric planetary gearbox with a 16:1 reduction ratio, delivering 260 N.m continuous output torque at 100 rpm and 30 °C (2301.2 lbf.in). Rated efficiency is 94 %, and the noise level at 1 m under no-load is 65 dB — quiet enough for a machine-tool or packaging line without an enclosure.
Load ratings and service life — what the numbers mean for the application
The maximum output torque reaches 416 N.m (3681.9 lbf.in) at 100 rpm and 30 °C, but the continuous rating of 260 N.m is the figure to size against for sustained duty — the 30,000-hour service life is quoted at the continuous torque and speed. Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour life, or 2800 N if you accept a 10,000-hour life at the same speed and temperature. Radial force (Fr) at mid-span on the output shaft is 1500 N for 30,000 hours, 2000 N for 10,000 hours. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arc.min — this is a standard-precision gearbox, not a zero-backlash servo unit, so factor the backlash into positioning budgets.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric lists the GBX1200161403F as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here.
Mechanical integration — 120 mm diameter, IP54 shaft output
The gearbox has a 120 mm external diameter (4.7 in), black anodized aluminium housing, and a C45 steel output shaft. Shaft output sealing is IP54 — suitable for indoor, dry environments; not rated for washdown. The unit is lubricated for life — no maintenance oil changes required.
