26 N.m planetary gearbox — obsolete, sourced per RFQ
The GBX0400090701F is a Schneider Electric planetary gearbox with a 40 mm diameter housing, 9:1 reduction ratio, and a maximum output torque of 26 N.m at 100 rpm and 30 °C ambient. It is classified as obsolete per the manufacturer's lifecycle status. The 94 % efficiency rating means under 6 % of input power is lost as heat inside the gearbox, which is relevant for thermal budgeting in a confined enclosure. The 30000-hour service life at rated load (100 rpm, 30 °C) gives a baseline for maintenance planning, though actual life depends on duty cycle and ambient temperature.
Load capacities and environmental limits
Maximum axial force (Fa) is 200 N for a 10000-hour life at 30 °C, derated to 160 N for the full 30000-hour service life. Maximum radial force (Fr) follows the same derating curve, applied at mid-distance from the output shaft. These limits define the allowable overhung load and thrust load from the driven mechanism. Torsional rigidity is 1.1 N.m/arcmin — the gearbox twists 1 arcminute for each 1.1 N.m of applied torque. Maximum torsional backlash is 28 arcmin, which is the angular play at the output shaft when reversing direction. For positioning applications requiring repeatability better than ±0.5°, this backlash figure must be accounted for in the system error budget. The IP54 rating on the shaft output means the output seal is protected against dust ingress and splashing water, but the gearbox body itself is not sealed — mounting orientation and enclosure integration determine the actual environmental protection.
Lifecycle and sourcing — obsolete, no direct successor
Schneider Electric lists the GBX0400090701F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at the time of RFQ. No pin-compatible or functionally equivalent drop-in replacement from the same manufacturer has been designated. The gearbox is lubricated for life, so no field lubrication schedule applies, but the 30000-hour service life should be factored into the spares plan.
