Planetary gearbox — 16:1 reduction, 120 N.m continuous
The GBX0800161403F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with an 80 mm housing diameter and a 16:1 reduction ratio. It delivers 120 N.m continuous output torque at 100 rpm, with a maximum of 192 N.m at the same speed. Rated service life is 30000 hours at 100 rpm and 30 °C ambient — the lubrication is sealed for life, so no maintenance interval applies. Torsional rigidity is 6.5 N.m/arcmin, with a maximum backlash of 14 arcmin — this matters for positioning accuracy in indexing or pick-and-place axes where cumulative error must stay within the repeatability budget.
Load ratings and overhung force limits
Maximum axial force (Fa) is 1200 N at 100 rpm for a 10000-hour life, derated to 900 N for the full 30000-hour service life at 30 °C. Maximum radial force (Fr) is 950 N at 100 rpm for 10000 hours, dropping to 650 N for 30000 hours — both measured at mid-span on the output shaft. The housing is black anodized aluminium; the output shaft is C45 steel. Shaft output seal is rated IP54 — suitable for dry indoor environments but not washdown or outdoor exposure. Ambient operating range is -25 to 90 °C. Noise level at 1 m under no-load is 60 dB — this is a straight-tooth gear set, so it will be audibly louder than a helical gearbox under load.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0800161403F as obsolete. Available through independent surplus and broker channels. For a new-design replacement, look at the current GBX series offerings from Schneider — the 80 mm frame size and 16:1 ratio are common, but verify the output torque, backlash, and mounting interface against this unit's spec sheet.
