60:1 planetary reduction, 110 N.m continuous
This GBX0800600551F is a 80 mm planetary gearbox with a 60:1 reduction ratio, delivering 110 N.m continuous output torque at 100 rpm and 30 °C. The straight-tooth design keeps backlash to 16 arc.min maximum — tight enough for positioning axes that don't need zero-backlash stages. Efficiency sits at 94 %, which means about 6 % of the input power goes to gear mesh losses. At 110 N.m output the thermal rise stays within the -25 to 90 °C ambient window the housing can shed.
Load ratings and service life
Rated for 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous running at rated load. The maximum output torque hits 176 N.m (1557.7 lbf.in) at the same speed and temperature, so there's 60 % headroom above continuous for acceleration peaks or momentary overloads. Axial and radial load limits are speed- and life-dependent: at 100 rpm and 30 °C, the shaft takes 1200 N axial for 10,000 hours or 900 N for the full 30,000-hour life. Radial force at mid-shaft is 950 N for 10,000 hours, dropping to 650 N for 30,000 hours. These are the numbers to check against your belt tension or overhung load.
Construction and environment
Shaft output seal is IP54 — splash-proof but not washdown-rated. Fine for dry indoor environments or occasional coolant mist; don't hose it down directly. Noise level is 60 dB at 1 m no-load — quieter than a typical conveyor drive, noticeable in a quiet assembly cell.
Obsolete — sourcing through independent channels
Schneider Electric lists this GBX0800600551F as obsolete. The only supply path is through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that needs this exact 60:1 ratio and 80 mm frame, the obsolete status means you're buying against whatever inventory remains in the distribution channel. The spread is in the gap between the original list price and what the surplus market asks — and that gap moves with remaining stock. A clean ship every time depends on the supplier's traceability; we qualify each lot before quoting.
