Planetary architecture distributes the load across multiple planet gears, giving higher torque density than a parallel-shaft reducer of the same envelope. Continuous output torque is 16.5 N·m at 100 rpm and 30 °C ambient; maximum intermittent torque reaches 26 N·m under the same conditions. Efficiency is 94 % at rated load, meaning 6 % of the input power is lost as heat inside the housing. For a motor driving this gearbox at, say, 200 W input, about 12 W must be dissipated through the 40 mm aluminium body — no external cooling is needed at that level, but the thermal path is limited by the housing surface area. ## Backlash, rigidity, and load limits — the positioning side of the spec Maximum torsional backlash is 28 arc-minutes, which is typical for an economy planetary stage with straight teeth. For indexing or positioning applications that need repeatability under 0.5°, this gearbox introduces enough lost motion that the controller must account for it — or a lower-backlash (helical or preloaded) stage should be selected. Torsional rigidity is 1.1 N·m/arcmin — the shaft wind-up under load. At the continuous torque of 16.5 N·m, the elastic twist is about 15 arc-minutes, which adds to the measured backlash in a real system. Maximum axial force on the output shaft is 200 N for a 10,000-hour life, derated to 160 N for the full 30,000-hour service life. Radial force limits are identical: 200 N at mid-shaft for 10,000 hours, 160 N for 30,000 hours. These are the bearing load ceilings — an overhung pulley or sprocket must be sized so the resultant force stays below the 30,000-hour curve. ## Obsolete — sourcing the GBX0400091404F through independent channels Schneider Electric lists the GBX0400091404F as obsolete. The part is sourced through independent distribution — quantities are confirmed at RFQ, and the available lots carry original Schneider packaging and traceability. The gearbox is lubricated for life and sealed to IP54 at the shaft output, so it arrives ready to install — no oil fill or breather venting is needed. The 40 mm housing diameter and 9:1 ratio are the two dimensions that must match the existing BOM position; the C45 steel shaft and black anodized finish are standard for the GBX series.","metaTitle":"Schneider Electric GBX0400091404F Planetary Gearbox, 9:1","metaDescription":"Schneider Electric GBX0400091404F planetary gearbox, 9:1 reduction, 16.5 N·m continuous torque, 94% efficiency.
