Is GBX1600321384D still being built?
GBX1600321384D sits in the Schneider Electric GBX planetary gearbox family with a published status of Obsolete, so new factory production has ended and remaining inventory moves through independent surplus channels rather than factory stock.
What this gearbox actually delivers
Reduction ratio is 32:1 in a single planetary stage, with straight-cut teeth and a stated efficiency of 94 % — that figure sets the thermal and torque-loss budget on a 30 °C-ambient, lubricated-for-life service envelope and is the number a drive sizing calc has to absorb. Continuous output torque is rated 800 N.m, with a maximum output torque of 1280 N.m — the gap between the two is the acceleration and peak-load headroom the gearbox can absorb for short duty cycles before the bearing and gear-mesh life budget starts to spend down. Service life is quoted at 30000 h at 100 rpm and 30 °C ambient, and the published axial and radial load limits — 6000 N axial and 4200 N radial at 100 rpm over that 30000 h envelope — assume the load is applied at mid-distance from the output shaft; the 8000 N axial and 6000 N radial figures for 10000 h show how much the bearing budget tightens when the service target shortens. Maximum torsional backlash is 10 arc.min and torsional rigidity 41 N.m/arcmin, which sets the positioning repeatability floor for any servo pairing — pairing the gearbox to a high-resolution drive with the published moment of inertia of 6.36 g.cm² gives the coupling engineer the inertia and stiffness terms needed to keep the loop stable.
Operating envelope and mechanical integration
Ambient operating range is -25...90 °C with an IP54 rating at the shaft output, so the gearbox is sealed for general industrial mounting rather than washdown; the housing is black anodized aluminium with a C 45 steel output shaft, and any-position mounting is permitted, which simplifies the mechanical layout when the reducer is paired with a servo or stepper drive in a constrained cabinet. Noise level is 70 dB at 1 m no-load — meaningful for operator-station placement and acoustic-enclosure decisions on packaging and converting lines where the reducer sits close to the human-machine interface.
Sourcing posture for an obsolete reducer
If the GBX1600321384D BOM line cannot be filled from independent stock, the cross-reference question is whether an active GBX-series planetary gearbox with the same 160 mm frame and 32:1 reduction can be specified as a functional replacement — the rated 800 N.m continuous, 1280 N.m peak, and 10 arc.min backlash figures are the spec lines the replacement has to meet before any form-fit-function call is made.
