Compatibility code GBX keeps the unit inside the same mounting and shaft envelope as the rest of the series, so it drops into a Lexium/BMI servo train or any standard servo-to-gearbox coupling without adapter plates (cites:,). ## Torque, backlash, and torsional rigidity — sizing the load Continuous output torque is rated 450 N.m, peaking at 720 N.m — the figure the drivetrain designer treats as the envelope for shock loads on start/stop cycles, not the steady-state rating (cites:,). Maximum torsional backlash is 6 arc.min, with torsional rigidity at 38 N.m/arcmin — adequate for point-to-point motion on packaging and pick-and-place axes where wind-up drift would otherwise bias the position loop (cites:,). Moment of inertia at the input is 4.63 g.cm², which is what the servo tuning engineer uses when sizing the Kp/Kv gains — a low reflected inertia keeps the velocity loop responsive at high reduction (cites:). ## Shaft loads and operating envelope Maximum radial force Fr is 4200 N at mid-distance from the output shaft over a 30000-hour life at 100 rpm (100 rpm, 30 °C); 6000 N is allowed for a shorter 10000-hour service life (cites:). Maximum axial force Fa is 6000 N over 30000 hours at 100 rpm, rising to 8000 N over a 10000-hour service life — both figures valid at 30 °C ambient (cites:). Ambient temperature for operation is -25 to 90 °C, and the shaft output carries an IP54 seal rating — meaning dust-protected and splash-resistant at the through-shaft, but not rated for direct high-pressure washdown (cites:,). ## Efficiency, acoustics, and mechanical life Efficiency is listed at 96 %, which for a single-stage 8:1 planetary is the figure the energy-balance check expects — the 4 % loss lands mostly as heat in the gearbox housing and small part in windage and churning (cites:). Noise level is 70 dB at 1 m under no-load conditions; in a packed panel or near a workstation, that is the floor the integrator plans acoustic treatment around, and the load-dependent component is on top of this baseline (cites:). Service life is 30000 hours at 100 rpm and 30 °C, and the gearbox is lubricated for life — no scheduled oil change, so the end-of-life decision is mechanical wear, not fluid condition (cites:,). ## Lifecycle and sourcing posture Let me be transparent: a current-status part sourced across regional authorized channels can carry the same SKU with the same factory build, but warranty coverage tracks the selling region — so for a European BOM, APAC-stock units ship genuinely equivalent but with regional warranty paperwork, not Schneider global. Quoted to order against the BOM here; availability and the current unit price confirmed against the RFQ (cites:,).","metaTitle":"Schneider Electric GBX1600081084D Planetary Gearbox, 8:1","metaDescription":"GBX1600081084D planetary gearbox, 160 mm, 8:1 reduction, 720 N.m peak / 450 N.m continuous, IP54 shaft.
