What this GBX0400031401F planetary gearbox delivers
The GBX0400031401F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, built with straight-cut teeth and a 3:1 reduction ratio. The 94 % efficiency figure is the mechanical throughput — at the rated 30,000-hour service life (100 rpm, 30 °C, lubricated for life) the gearbox loses only 6 % of input power to friction and windage, which is typical for a single-stage planetary with straight teeth at this size. Maximum torsional backlash is 24 arc.min, and torsional rigidity is rated at 1 N.m/arcmin — the stiffness figure tells you the angular wind-up under load: at 11 N.m (the torque implied by the description), expect roughly 11 arcmin of twist across the gear train before the output shaft moves. For indexing or positioning applications, that backlash budget sets the repeatability floor.
Mechanical ratings and load capacity
Maximum axial force (Fa) is 160 N at 100 rpm over the full 30,000-hour life at 30 °C. Maximum radial force (Fr) is 200 N at 100 rpm when applied at mid-distance from the output shaft, but that figure drops to 160 N if you need the same 30,000-hour life — the bearing load-life trade-off is built into the spec. The shaft is machined from C45 carbon steel, and the housing is black anodized aluminium, giving a corrosion-resistant exterior that suits clean, dry environments. The lubrication is sealed for life — no maintenance ports, no oil-change interval.
Lifecycle status and sourcing
Sourced through independent surplus and new-old-stock channels. The gearbox is lubricated for life and ships in its original packaging (1 unit per package).
