Planetary gearbox, 40 mm, 4:1 reduction
The GBX0400041401F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 40 mm external diameter and a 4:1 reduction ratio. It delivers a continuous output torque of 15 N.m at 100 rpm and 30 °C, with a maximum output torque of 24 N.m under the same conditions. Rated efficiency is 94 %, and the noise level at 1 m under no-load is 55 dB — quiet enough for a benchtop or light conveyor drive without additional enclosure damping.
Torque, life, and mounting constraints
Service life is rated at 30,000 hours at 100 rpm and 30 °C, with the gearbox lubricated for life — no maintenance oil changes. The black anodised aluminium housing carries an IP54 rating at the shaft output, meaning it resists dust ingress and splashing water but is not suited for pressurised washdown. Maximum axial force (Fa) is 200 N at 100 rpm for a 10,000-hour life, dropping to 160 N for the full 30,000-hour rating. Radial force (Fr) follows the same derating: 200 N at 10,000 hours, 160 N at 30,000 hours, with the force applied at mid-distance on the output shaft. Torsional backlash is 30 arcmin maximum — a standard figure for this class of straight-tooth planetary, not a precision-zero-backlash stage. Ambient operating temperature spans -25 to 90 °C, so it can live inside a warm cabinet or near a motor without derating. The shaft is C45 steel, and the housing is black anodised aluminium.
Obsolete — sourcing through independent channels
Schneider Electric has marked the GBX0400041401F as obsolete. The part is available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. For a BOM that needs this exact 40 mm, 4:1, 15 N.m planetary, the only path is the secondary market. No stock-holding claim; every unit is verified before shipment.
