20:1 planetary gearbox for precision motion
The GBX0600201404F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 20:1 reduction ratio and straight-tooth gearing. It delivers a continuous output torque of 44 N.m (389.4 lbf.in) at 100 rpm and 30 °C, with a maximum intermittent torque of 70 N.m (619.6 lbf.in) under the same conditions. Rated efficiency is 94 %, meaning about 6 % of input power is lost as heat — a figure that matters for thermal management in a confined cabinet or when the gearbox is mounted near heat-sensitive components.
Backlash, forces, and service life
Maximum torsional backlash is 20 arc.min — typical for a straight-tooth planetary at this price point, but a buyer positioning a load that reverses direction should confirm this meets the application's repeatability budget. The output shaft carries a maximum axial force of 450 N and a maximum radial force of 340 N when the force is applied at mid-span, both rated for the full 30,000-hour service life at 100 rpm and 30 °C. Short-duration overloads (10,000-hour life) allow 600 N axial and 500 N radial. Torsional rigidity is 2.5 N.m/arcmin — a measure of how much the gearbox winds up under load; lower is stiffer, and this figure is adequate for indexing and positioning tasks that don't require zero-backlash performance.
Obsolete — sourced through independent channels
Schneider Electric lists the GBX0600201404F as obsolete. The part is available through independent surplus and new-old-stock channels; quantities are confirmed at RFQ. The gearbox is lubricated for life (no maintenance ports), operates from -25 °C to 90 °C ambient, and carries an IP54 rating at the shaft output — suitable for dusty or condensing environments but not for washdown.
