The GBX0800401003F is a straight-tooth planetary gearbox with an 80 mm outer diameter and a 40:1 reduction ratio. The continuous output torque is 110 N.m at 100 rpm and 30 °C, with a maximum intermittent torque of 176 N.m at the same speed and temperature — the margin covers acceleration peaks and occasional overloads without oversizing the next stage. Efficiency sits at 94 %, which is typical for a single-stage planetary of this ratio. The 14 arc-min maximum torsional backlash places it in the standard-precision class — adequate for positioning conveyors, rotary indexing tables, and general motion axes where the load doesn't reverse direction under high torque.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric lists the GBX0800401003F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a BOM freeze or a line-down replacement, the 80 mm frame size and 40:1 ratio narrow the field to other planetary gearboxes with the same mounting interface and output shaft dimensions — verify the input bore and keyway against the motor shaft before committing.
Mechanical limits — axial and radial load capacity at rated life
The output shaft accepts a maximum axial force of 1200 N at 100 rpm for a 10,000-hour service life at 30 °C, derated to 900 N for the full 30,000-hour life. Radial force at mid-span on the output shaft is 950 N for 10,000 hours and 650 N for 30,000 hours — these are the load limits that govern belt-drive or overhung-pulley applications. Torsional rigidity is 6.5 N.m/arcmin, which means the gearbox winds up about 0.15 arcmin per N.m of applied torque. In a servo loop with high-gain position control, this windup adds to the total compliance budget and may limit the achievable bandwidth.
Environmental and integration details
The housing is black anodized aluminium with an IP54 rating at the shaft output — protected against dust ingress and splashing water, but not submersion. The operating ambient range is -25 to 90 °C, and the unit is lubricated for life, so no maintenance schedule for oil changes. Noise level is 60 dB at 1 m under no-load conditions — quiet enough for a machine-tool environment without additional enclosure damping. The shaft is C45 steel, standard for this class.
