What this planetary gearbox is — and what it's not
The GBX0801000701F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, 80 mm diameter, with a 100:1 reduction ratio and 120 N.m continuous output torque at 100 rpm. The straight-tooth design gives it a higher noise floor than a helical planetary — expect 60 dB at 1 m no-load — but keeps the backlash predictable at 16 arc-min maximum, which matters for positioning accuracy in indexing or pick-and-place axes. The housing is black anodised aluminium, shaft output rated IP54 — splash-resistant at the seal face, but not submersible. Lubricated for life, so no oil-change schedule on the maintenance card.
Torque, life, and the real load limits
Rated 120 N.m continuous at 100 rpm, 30 °C — that's the number to size against for steady-state duty. The maximum output torque peaks at 192 N.m, but that's at the same speed and temperature; sustained operation above 120 N.m shortens the 30,000-hour service life. The axial and radial force limits are load-position-dependent: 1200 N axial for a 10,000-hour life, dropping to 900 N if you want the full 30,000 hours. Radial force at mid-span on the output shaft is 650 N for the long life, 950 N for the shorter window. Torsional rigidity is 6.3 N.m/arcmin — a measure of how much the gear train winds up under load. For a servo-driven axis, that stiffness determines the bandwidth you can tune without oscillation. The 16 arc-min backlash is typical for a standard-precision planetary; if your application needs under 5 arc-min, this isn't the box.
Obsolete — sourcing reality
Schneider Electric lists the GBX0801000701F as obsolete. That means the only channel is independent surplus or broker inventory — quantities are lot-specific and confirmed at the time of RFQ. No stock-holding claim here; each order is quoted against what's available in the field.
