Planetary gearbox, 160 mm, 5:1 — torque and backlash specs
The GBX1600050554F is a 160 mm-diameter planetary gearbox from Schneider Electric's GBX series, with straight-cut teeth and a 5:1 reduction ratio. Maximum output torque hits 720 N.m at 100 rpm, with a continuous rating of 450 N.m at the same speed — both figures at 30 °C ambient. Torsional backlash is held to 6 arc-min maximum, and torsional rigidity is 38 N.m/arcmin — the stiffness matters for positioning accuracy in indexing or pick-and-place applications where load reversal creates lost motion.
Load ratings, service life, and environmental limits
Rated service life is 30,000 hours at 100 rpm and 30 °C — the lubricated-for-life design means no oil changes over that interval. Maximum axial force (Fa) is 6000 N at 100 rpm for the full 30,000-hour life, or 8000 N if you accept a shorter 10,000-hour window. Radial force (Fr) follows the same pattern: 4200 N for 30,000 hours, 6000 N for 10,000 hours, with force applied at mid-span on the output shaft. Operating temperature range spans -25 to 90 °C, and the shaft output carries an IP54 ingress rating — protected against dust and splashing water, but not submersion. Noise level is 70 dB at 1 m under no-load conditions.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1600050554F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or form-fit-function replacement from the original manufacturer is documented.
