The GBX0800800702F is a straight-tooth planetary gearbox with an 80:1 reduction ratio, delivering 120 N.m continuous output torque at 100 rpm. That 120 N.m figure is the sustained load the gearbox can carry across its 30000-hour service life at 30 °C — push it to 192 N.m maximum and you're into intermittent duty, not continuous. Efficiency sits at 94 %, which is typical for a single-stage planetary of this size — the straight-tooth profile keeps rolling losses low but trades some smoothness for the helical alternative. Noise level is 60 dB at 1 m, no-load, so it's quiet enough for indoor conveyor or packaging lines where operator exposure matters.
Obsolete — sourcing reality for a line-down spare
Schneider Electric lists this gearbox as obsolete. The only channel is independent surplus — quantities are lot-specific and confirmed at RFQ. If you're holding a BOM line with this order code, the buy window is whatever stock exists in the broker channel. The gearbox is lubricated for life, so there's no maintenance oil-change schedule — one less thing to worry about when pulling a spare from storage. Shaft output is IP54, meaning it's splash-protected but not washdown-rated; keep it out of direct hose-down zones.
Mechanical limits — axial and radial force budgets
Maximum axial force Fa is 1200 N at 100 rpm for a 10000-hour life, dropping to 900 N if you need the full 30000-hour service life. Radial force Fr at mid-shaft is 950 N for 10000 hours or 650 N for 30000 hours. These are the numbers that govern belt-drive or direct-coupling designs — overshoot them and the bearing life collapses. Torsional backlash is 16 arc.min maximum, which is standard for a commercial planetary — not a precision servo gearhead. If your application indexes or reverses frequently, that backlash will show up as lost motion at the load.
