The unit ships lubricated for life in a black anodized aluminium housing with a C 45 steel output shaft, so installation is bolt-down and forget — there is no service interval to schedule on the gearbox itself. Torsional rigidity is listed at 38 N.m/arcmin and maximum torsional backlash at 6 arc.min — together those define how precisely the gearbox holds position under reversing load, which is the figure that matters on indexing tables and rotary axes where a few arc-minutes of wind-up show up as a positional error on the downstream machine. ## Torque envelope and load ratings Continuous output torque is 400 N.m with a maximum output torque of 640 N.m, and the gearbox delivers 96 % efficiency at the listed operating point — the loss budget is small enough that thermal soak is not the gating constraint in a normal duty cycle. The moment of inertia at 12.14 g.cm² is the figure a servo loop needs to size the acceleration feed-forward, because it adds directly to the reflected load inertia through the 3:1 ratio. Maximum radial force Fr is 4200 N at 100 rpm over the 30000 h service life (6000 N if derated to a 10000 h life), and maximum axial force Fa is 6000 N at 100 rpm over 30000 h (8000 N over 10000 h), with the force applied at mid-distance from the output shaft. The 30000 h figure at 100 rpm and 30 °C is the headline service life — running hotter, faster, or with a sustained side-load above the listed curve shortens it. The shaft output carries an IP54 rating, so the sealing envelope is suitable for general industrial interiors; it is not a washdown-duty seal and should not be specified for food-grade or outdoor exposed service without an additional boot or guard. Acoustic signature is 70 dB at 1 m under no-load — straight-tooth geometry is louder than a helical or planetary-helical stage at the same reduction, and that figure is the floor the installer will hear during a slow approach or a dwell condition. The compatibility code GBX locks the mating face to other units in the same family; substituting a gearbox from a different series without checking the input pilot and bolt circle is the usual way these parts get misapplied. ## Lifecycle — obsolete, sourced on RFQ GBX1600031083D is recorded as obsolete on the manufacturer record, with no official successor or cross-reference listed. That puts it firmly in the independent-distribution channel — stock on hand is lot-specific, age varies, and availability is confirmed per quote rather than promised off the shelf. For a maintenance spare or a planned retrofit, the realistic sourcing path is an RFQ against independent inventory: pricing and quantity are quoted to order against the specific lot on hand, and lead time follows whatever traceable stock exists at the time of the query. No factory-direct or authorised-channel claim applies here.","metaTitle":"Schneider Electric GBX1600031083D Planetary Gearbox, 3:1","metaDescription":"GBX1600031083D — Schneider Electric GBX planetary gearbox, 160 mm, 3:1 reduction, 400 N.m continuous / 640 N.m peak.
