Obsolete — sourcing the GBX0800090554F for legacy lines
Schneider Electric has marked the GBX0800090554F as obsolete. No official successor is listed, so this planetary gearbox is available only through independent surplus and broker channels.
9:1 planetary reduction, 80 mm frame
Continuous output torque is 130 N.m at 100 rpm and 30 °C, with a peak of 208 N.m under the same conditions — the margin between continuous and maximum tells you the overload headroom for short-duration peaks. Efficiency sits at 94 %, which is typical for a single-stage planetary of this size. The noise level at no-load is 60 dB measured at 1 m — useful to know if the gearbox runs in an operator-occupied area.
Load ratings and service life
Rated service life is 30000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no oil changes, no breather, no maintenance schedule on the lube side. Maximum axial force on the output shaft is 1200 N for a 10000-hour life, derating to 900 N if you need the full 30000-hour service. Radial force follows the same pattern: 950 N for 10000 hours, 650 N for 30000 hours, both measured at mid-span on the output shaft. Torsional rigidity is 6.5 N.m/arcmin — this is the stiffness number that matters for positioning accuracy under varying load. Maximum torsional backlash is 14 arc.min, which sets the repeatability floor in a reversing or indexing application.
Environmental and mounting constraints
The shaft output seal carries an IP54 rating — splash-resistant but not washdown-rated, so keep it out of direct hose spray. The 80 mm body diameter and straight-tooth planetary design mean it mates with standard NEMA or IEC motor flanges in the same frame class. Confirm the input bore and keyway dimensions against your motor shaft before committing the BOM line.
