Stockroom note: this code is flagged Obsolete on the manufacturer record, so it no longer rolls off the factory line — the supply path is independent surplus and lot-traceable brokers, with quantity and condition confirmed against an RFQ rather than a live production schedule. ## Torque envelope, backlash, and the duty it actually survives Continuous output torque is rated at 800 N.m with a maximum output torque ceiling of 1280 N.m, and torsional rigidity is published at 41 N.m/arcmin — the stiffness figure matters more than the peak torque for any application that depends on positioning repeatability rather than raw lifting force. Maximum torsional backlash is 10 arc.min, which puts this gearbox in the mid-precision band — fine for conveyors, mixers, and indexing tables where cumulative wind-up is acceptable, but a tighter unit is needed for high-accuracy servo positioning. Service life is quoted at 30000 h at 100 rpm and 30 °C, and the unit is lubricated for life — meaning no relube interval to schedule on the maintenance route, but the 30000 h envelope is the one that drives the rebuild/replacement decision rather than the headline torque numbers. ## Shaft loads the bearings will actually carry Maximum radial force Fr is 4200 N at 100 rpm over the 30000 h life when the load is applied at mid-distance from the output shaft, rising to 6000 N if the application is limited to 10000 h at 100 rpm — the lower rating is the duty-life curve the integrator has to size against. Maximum axial force Fa is 6000 N at 100 rpm over 30000 h at 30 °C, with an 8000 N limit available when the duty is capped at 10000 h — the published numbers are coupled to the life figure, so quoting one without the other gives a misleading safety margin. Moment of inertia is 12.37 g.cm² and the shaft is C 45 steel — the inertia figure feeds back into the servo sizing math, and the shaft material is what governs any keyway or coupling spec the integrator commits to downstream. ## Mounting, sealing, and ambient envelope Mounting position is listed as any position, which removes the orientation constraint many helical and worm units impose, and the shaft output carries an IP54 rating — adequate for indoor cabinet-mounted and sheltered field installations but not for direct washdown exposure.","metaTitle":"Schneider Electric GBX1600121383D Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX1600121383D obsolete planetary gearbox, 12:1 ratio, 800 N.m continuous, Ø160 mm.
