Planetary gearbox, 80:1 reduction, 260 N.m continuous
The Schneider Electric GBX1200801403F is a planetary gearbox with straight teeth, 120 mm housing diameter, and an 80:1 reduction ratio. It delivers 260 N.m continuous output torque at 100 rpm, with a peak of 416 N.m for intermittent duty. Efficiency sits at 94 %, and the unit is lubricated for life — no oil changes over the 30,000-hour service life at rated load. Noise level is 65 dB at 1 m, no-load, which is quiet for a planetary stage at this ratio.
Load ratings and mechanical limits
Maximum radial force on the output shaft is 1500 N at mid-span for the full 30,000-hour life, or 2000 N if you accept a shorter 10,000-hour window. Maximum axial force is 2100 N at 30,000 hours, 2800 N at 10,000 hours — both at 100 rpm and 30 °C ambient. Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 14 arc.min — that's standard precision for a straight-tooth planetary, not a zero-backlash unit. The shaft output seal carries an IP54 rating, so it handles dust and splashing water but not washdown. The black anodized aluminium housing keeps corrosion at bay in most industrial environments. Shaft material is C45 carbon steel.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX1200801403F as obsolete. No official successor part number is published. This unit is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that needs this exact ratio and torque rating, the GBX1200801403F is the only direct fit. There is no pin-compatible drop-in replacement from Schneider's current GBX line — a different frame size or ratio would change the mounting and coupling dimensions.
