9:1 planetary — 210 N.m continuous, 336 N.m peak
The GBX1200091403F is a Schneider Electric planetary gearbox with straight teeth, 120 mm diameter housing, and a 9:1 reduction ratio. It delivers 210 N.m continuous output torque at 100 rpm and 30 °C, with a maximum of 336 N.m at the same speed and temperature. Rated service life is 30,000 hours at 100 rpm and 30 °C — the gearbox is lubricated for life, so no maintenance interval for oil changes. The torsional rigidity of 13 N.m/arcmin and maximum backlash of 12 arc.min define the positioning repeatability for indexing or servo applications.
Load ratings and shaft limits
Maximum axial force (Fa) is 2100 N at 100 rpm for the 30,000-hour life, or 2800 N for a 10,000-hour duty cycle. Maximum radial force (Fr) is 1500 N at 100 rpm for 30,000 hours, or 2000 N for 10,000 hours — both measured at mid-distance from the output shaft. The output shaft is C45 steel, and the housing is black anodized aluminium. Shaft output sealing is IP54 — suitable for dry indoor environments but not washdown or outdoor exposure. Ambient operating range is -25 to 90 °C. Noise level is 65 dB at 1 m under no-load conditions — typical for a straight-tooth planetary at this size. Efficiency is 94 %, which is standard for a single-stage planetary reduction of this ratio.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1200091403F as obsolete. Available through independent surplus and broker channels. Quantities are lot-specific — confirmed at RFQ. No pin-compatible or direct mechanical replacement is documented by Schneider; a functional replacement would require verifying the mounting flange, shaft diameter, and keyway dimensions against the application.
