Maximum output torque is 1120 N.m with continuous output torque rated 700 N.m; torsional rigidity sits at 41 N.m/arcmin and maximum torsional backlash is 10 arc.min — numbers that put this in the mid-frame precision class rather than a heavy-industrial helical unit. Efficiency is listed at 94 % and the housing is black anodized aluminium with a C 45 shaft — lubed for life, so no field service on the grease. ## Loads, life, and the operating envelope Maximum axial load Fa is 6000 N at 100 rpm over 30000 h, rising to 8000 N if the duty is held to 10000 h; maximum radial load Fr is 4200 N at mid-span over 30000 h, or 6000 N over 10000 h — so the radial force the driven pulley or pinion can apply depends on how long you expect the gearbox to live. Service life is rated 30000 h at 100 rpm and 30 °C, with ambient operating temperature from -25 to 90 °C; the shaft output carries an IP54 seal, fine for an indoor cabinet or sheltered machine base, not a washdown or outdoor mount. Moment of inertia at the input is 5.28 g.cm² and the unit mounts in any position — useful when the gearbox has to live under a machine table rather than on a flat panel. Noise level is 70 dB measured at 1 m on the no-load bench — typical for a straight-tooth planetary at this frame, and a reason integrators usually spec a helical or skewed-tooth unit when the operator station sits close to the gearbox. ## Production status and how to source it GBX1600400843D is listed as obsolete with no official successor on the record — the unit lives on through independent surplus and broker channels, with availability and quantity tied to what's already in the field. There is no factory-direct cross. For a machine that already runs this gearbox, sourcing the same order code keeps the shaft, mounting footprint, and coupling geometry matched to the existing servomotor — a functional substitute in another frame would force a coupling change and a re-check of the axial/radial load envelope. Pricing and current availability for GBX1600400843D are confirmed against an RFQ — the obsolete status means stock is lot-specific, not a running factory line.","metaTitle":"Schneider Electric GBX1600400843D Planetary Gearbox, 40:1","metaDescription":"GBX1600400843D — 160 mm planetary gearbox, 40:1 reduction, 1120 N.m peak / 700 N.m continuous, efficiency 94%.
