9:1 planetary gearbox — 44 N.m continuous, 70 N.m peak
The GBX0600091404F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 9:1 reduction ratio and straight-cut teeth. Continuous output torque is 44 N.m at 100 rpm, with a maximum intermittent torque of 70 N.m at the same speed — the peak figure governs short-duration acceleration or overload events, while the continuous rating sets the thermal limit for steady-state duty. Efficiency is listed at 94 %, which is typical for a single-stage planetary stage at this ratio — the remaining 6 % is lost to gear mesh friction and bearing drag, dissipated as heat through the black anodised aluminium housing.
Load ratings and service life at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — this is the L10 life, meaning 90 % of a population will survive that long under rated load. At higher radial or axial loads the life drops: maximum radial force Fr is 340 N for 30,000 hours, or 500 N for 10,000 hours; maximum axial force Fa is 450 N for 30,000 hours, or 600 N for 10,000 hours. Both forces are specified with the load applied at mid-distance from the output shaft. Torsional rigidity is 2.5 N.m/arcmin — this is the stiffness of the output stage under load. For a positioning application, the 20 arcmin maximum torsional backlash means the output shaft can rotate up to 0.33° before the input gear engages; this is a standard backlash class for a straight-tooth planetary, not a precision-zero-backlash stage.
Obsolete — sourced through independent channels
Schneider Electric has marked the GBX0600091404F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible or dimensionally identical replacement is documented by Schneider; any functional substitute will require verifying the mounting flange, shaft diameter, and keyway dimensions against the existing installation. The gearbox is lubricated for life — no oil-change interval to plan for. The IP54 shaft output seal protects against dust ingress and splashing water, but the unit is not rated for washdown or submerged service. Operating ambient range is -25 °C to 90 °C.
