Frame, ratio, and the torque envelope
The GBX1600321084D is a straight-teeth planetary gearbox in the GBX family, 160 mm gearbox external diameter, with a 32:1 reduction ratio and a C 45 steel output shaft built to mount in any position around a black anodized aluminium housing (cites:,). Continuous output torque is rated 800 N·m, with a maximum output torque of 1280 N·m and a maximum torsional backlash of 10 arc.min — the figure a positioning application watches when the gearbox sits between a servo and the load (cites:,). Torsional rigidity is 41 N·m/arcmin and the moment of inertia is 6.36 g·cm² — low enough that the gearbox does not dominate the servo loop tuning at the input shaft (cites:,).
Service life against radial and axial load
Service life is rated 30000 h at 100 rpm at 30 °C, with the unit lubricated for life so no scheduled oil change interrupts the duty cycle (cites:,). At that 30000 h envelope the maximum radial force Fr is 4200 N applied at mid-distance from the output shaft, and the maximum axial force Fa is 6000 N — both figures double the load budget over a 10000 h horizon (Fr 6000 N, Fa 8000 N), giving the panel designer room to overspec the bearing loads when the application runs slower or cooler (cites:,). Ambient temperature for operation spans −25 to 90 °C, so the gearbox sits comfortably next to a servo drive cabinet without special enclosure cooling (cites:).
Efficiency, noise, and sealing
Efficiency is rated 94 %, which keeps motor sizing straightforward — only a few percent of the input power converts to heat inside the gearbox housing (cites:). Noise level is 70 dB at 1 m no-load, a figure that matters when the gearbox is mounted near operator stations rather than inside a sound-damped cabinet (cites:). The shaft output carries an IP54 degree of protection, sealing against dust ingress and water spray from the output side while the input coupling and motor adapter follow the mating half on the drive end (cites:).
Lifecycle and supply posture
Lifecycle status is active for the Schneider Electric GBX family, so the part is a current-production item rather than a phase-out buy (cites:,). Independent distribution quotes the GBX1600321084D to order against the BOM — lead time, lot size, and pricing confirmed at RFQ rather than carried as stock (cites:).
