GBX1600121384D at a glance
The Schneider Electric GBX1600121384D is a planetary gearbox in the GBX line, 160 mm gearbox external diameter, with straight-cut gearing and a 12:1 reduction ratio. The shaft is C 45 steel running in a black anodized aluminium housing, factory lubricated for life, and rated for continuous output torque of 800 N.m with a peak of 1280 N.m. Efficiency is 94 % and no-load noise is 70 dB at 1 m, both figures the spec table lists for this gearbox at its published rating. The unit is catalogued as Active under the GBX compatibility code and can be specified into a new BOM line without an obsolescence gate.
Torque, life window, and load envelope
Continuous output torque is rated 800 N.m; maximum output torque is 1280 N.m. Service life is 30000 h at 100 rpm and 30 °C, which is the envelope the load curves below are drawn against. Above that speed or temperature the bearing and gear life curves shorten accordingly, so the 30000 h figure should be treated as the design baseline rather than a worst-case guarantee. Maximum radial force Fr is 4200 N at 100 rpm over the 30000 h life when applied at mid-distance from the output shaft, and rises to 6000 N if the duty is constrained to 10000 h at 30 °C; maximum axial force Fa is 6000 N under the same 30000 h / 100 rpm / 30 °C envelope and 8000 N at the shorter 10000 h rating. These paired values let a designer trade shaft load against service life without leaving the published curves. Torsional rigidity is 41 N.m/arcmin and maximum torsional backlash is 10 arc.min — useful when this gearbox sits between a servo and a high-inertia load where wind-up and return play matter for positioning repeatability. The shaft output is sealed to IP54, so the gearbox is suitable for indoor industrial mounting rather than washdown or outdoor exposure.
Mechanical integration and operating envelope
Operating ambient temperature is -25 °C to 90 °C, mounting position is unrestricted (any position), and the moment of inertia at the input is 12.37 g.cm², which is what the upstream servo or stepper drive sees reflected back through the 12:1 reduction. Being lubricated for life removes one field-service item: there is no grease port or oil-level plug on this gearbox, so the integration plan can skip a maintenance access envelope around the housing.
Sourcing posture for GBX1600121384D
Current pricing and availability for GBX1600121384D are confirmed against the BOM line at quote time — lead time, volume breaks, and traceability are returned with the RFQ response rather than carried as fixed numbers on this listing.
