40 mm planetary gearbox — 4:1 reduction, 15 N.m continuous
The GBX0400040703F is a 40 mm diameter planetary gearbox from Schneider Electric's GBX series, with straight teeth 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 intermittent torque of 24 N.m under the same conditions. Efficiency sits at 94 %, and the torsional backlash is 30 arcmin — a standard figure for this class of straight-tooth planetary stage. The noise level at 1 m under no-load is 55 dB.
Shaft loads and service life — what the ratings mean
Rated service life is 30,000 hours at 100 rpm and 30 °C. The maximum axial force (Fa) is 200 N for a 10,000-hour target, dropping to 160 N for the full 30,000-hour life. Radial force (Fr) follows the same pattern: 200 N for 10,000 hours, 160 N for 30,000 hours, with the force applied at mid-distance from the output shaft. The shaft is C45 steel, the housing is black anodized aluminium, and the shaft output seal carries IP54 protection — suitable for indoor environments where dust and splash are present but not pressurized washdown. The gearbox is lubricated for life, so no maintenance schedule for oil changes — a sealed unit that runs until the grease degrades at end of service life.
Sourcing reality — obsolete, sourced to order
This part is marked obsolete by Schneider Electric. Availability is through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM that calls out this exact order code, the sourcing posture is quoted-to-order against the required quantity. No stock-holding claim; each lot is verified for authenticity and condition before shipment.
