The GBX1600081001F is a planetary gearbox from Schneider Electric's GBX series, sized for a 160 mm output-stage diameter and a straight-tooth profile that gives an 8:1 reduction ratio. That ratio is the fixed speed step — input at 1000 rpm gives you 125 rpm on the output shaft, no field adjustment. The 94 % efficiency means roughly 6 % of the input power is lost as heat inside the housing; for a 5 kW input that's about 300 W of thermal load the anodized aluminium body has to shed. Service life is rated at 30 000 hours at 100 rpm and 30 °C ambient — that's about 3.4 years of continuous run time before the lubricant and bearing wear reach end-of-life. The gearbox ships lubricated for life, so there's no oil-change interval to schedule.
Sourcing reality — obsolete, quoted to order
Schneider Electric has marked the GBX1600081001F as obsolete. This part is available through independent surplus and broker channels. Quantities are confirmed at RFQ time — the stock picture changes as lots come and go. We source it per your BOM line and quote the current availability and pricing against the RFQ.
Mounting and integration — what fits where
The 160 mm housing diameter and the IP54 shaft output seal mean this gearbox is designed for enclosed installation where the output shaft passes through a panel or machine frame — the seal keeps dust and splash out of the bearing cavity. Ambient operating range is -25 to 90 °C, which covers most indoor industrial environments but not washdown or outdoor direct-sun duty without a sunshade. Maximum axial force (Fa) on the output shaft is 6000 N for the full 30 000-hour life, or 8000 N if you accept a shorter 10 000-hour service window. Radial force (Fr) is 4200 N for the full life, 6000 N for the reduced life — both measured with the force applied at mid-distance along the output shaft. If your application exceeds these, the bearing life drops faster than linear.
