Planetary gearbox — 9:1 reduction, 130 N.m continuous rating
The GBX0800091401F is a Schneider Electric planetary gearbox with a 9:1 reduction ratio, delivering 130 N.m continuous output torque at 100 rpm and 30 °C ambient. Peak torque reaches 208 N.m under the same conditions, which is the overload ceiling before the gear train sees accelerated wear. Straight-tooth gearing in an 80 mm black anodized aluminium housing, with a C45 steel output shaft. The 14 arcmin torsional backlash is the angular positioning error at the output — for applications that index or reverse direction, this is the repeatability floor. Rated service life is 30,000 hours at 100 rpm and 30 °C. The unit is lubricated for life, so no oil-change interval to schedule — the failure mode is bearing and gear wear at the rated torque, not lubrication degradation.
Efficiency, noise, and thermal limits
Listed at 94% efficiency, meaning 6% of input power is lost as heat through the housing. For a 130 N.m output at 100 rpm (roughly 1.36 kW output), the heat rejection is about 87 W — the aluminium housing and natural convection handle that at 30 °C ambient, but derate if enclosed or above 30 °C. Noise level is 60 dB at 1 m, no-load. That is quiet for a straight-tooth planetary — helical gears would be quieter but cost more and introduce axial thrust the bearings must carry. The 60 dB figure is a no-load benchmark; under load the gear mesh noise rises with torque. The lower bound matters for cold-start viscosity of the lifetime grease; the upper bound is the housing temperature limit, not the internal gear contact temperature. Above 90 °C ambient, the grease degrades faster than the 30,000-hour rating assumes.
Shaft loading and environmental sealing
Maximum axial force (Fa) is 1200 N at 100 rpm for 10,000 hours at 30 °C, dropping to 900 N for the full 30,000-hour service life. Radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours. These are the overhung load limits — exceeding them shortens bearing life faster than torque overload does. Shaft output sealing is rated IP54 — dust-protected and splash-resistant, not submersible. The IP54 rating applies to the shaft exit seal; the housing itself is sealed by the anodized finish and O-rings at the joints. Not suitable for washdown or outdoor exposure without additional enclosure protection.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX0800091401F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that requires this exact reduction ratio (9:1), output torque (130 N.m continuous), and 80 mm housing diameter, the GBX0800091401F is the drop-in fit. A functional replacement from another manufacturer would need to match the mounting flange pattern, shaft diameter, and keyway — not just the ratio and torque.
