Planetary gearbox, 40 mm, 3:1, 94 % efficiency
The GBX0400031402F is a 40 mm-diameter planetary gearbox from Schneider Electric's GBX series, with a 3:1 reduction ratio and 94 % efficiency — a tight, straight-tooth design for motion-control applications where space is at a premium. Rated service life is 30,000 hours at 100 rpm and 30 °C ambient, with the gearbox lubricated for life and sealed in a black anodized aluminium housing.
Load ratings and backlash — what they mean for your axis
Maximum axial force is 200 N at 100 rpm for a 10,000-hour life, dropping to 160 N for the full 30,000-hour service interval — the same derating applies to radial force (200 N / 160 N at mid-shaft). Torsional backlash is 24 arcmin maximum — this is a standard-precision grade, not a zero-backlash unit. If your application requires repeatable positioning under reversing loads, budget for this lash in the control loop or consider a preloaded alternative. Torsional rigidity is 1 N·m/arcmin, meaning the shaft wind-up under rated torque stays within predictable bounds for a 40 mm frame.
Lifecycle reality — obsolete, but we source it
Schneider Electric lists the GBX0400031402F as obsolete — no direct factory replacement is published for this order code. We source this part through independent surplus channels; quantities are lot-specific and confirmed at RFQ. If you are holding a BOM that calls out this exact gearbox, this is the last-time-buy window — buy what you need for the remaining service life of the machine.
