Pairing this GBX to a servo axis without under-sizing the gearbox
The GBX1600161382D is a planetary gearbox in Schneider Electric's GBX family, Ø160 mm frame with straight-cut teeth and a 16:1 reduction ratio, sized for servo applications where continuous output torque sits at 800 N·m and peak torque reaches 1280 N·m. The 800 N·m continuous figure is the one that should govern motor pairing — picking a servo whose stall torque exceeds the gearbox's continuous rating without a thermal margin will trip the service-life budget, since the box is rated for 30,000 h at 100 rpm and 30 °C. Shaft loading must be checked against the duty profile: maximum radial force is 4200 N over the 30,000 h life (6000 N if the duty is capped at 10,000 h), and maximum axial force is 6000 N over 30,000 h (8000 N over 10,000 h), all referenced at 100 rpm and 30 °C — the 10,000 h column is the higher force budget a buyer can draw on when service hours are limited.
Efficiency, noise, and the operating envelope
Efficiency is 94 %, and the no-load noise figure is 70 dB at 1 m — straight-tooth gearing is louder than helical, so the 70 dB reading is the floor to expect rather than a peak under load, and the buyer should budget acoustic enclosure if the gearbox sits near an operator station. Mechanical signature worth noting on the nameplate: torsional rigidity 41 N·m/arcmin, maximum torsional backlash 10 arc.min, moment of inertia 7.47 g·cm², with a C45 shaft in a black anodized aluminium housing — the <10 arc.min backlash and the rigidity figure put it in the mid-precision band where servo indexing is achievable without a separate low-backlash stage.
Sourcing posture for the GBX1600161382D
For buyers running parallel-import or cross-region procurement, the part is genuinely the same whether it ships from European or APAC authorized channels — same part, different passport — and the only difference is which regional warranty trail the box carries; that is the call the buyer needs to make before placing the BOM line, not a question of authenticity.
