What this gearbox delivers — torque, ratio, and service life
The GBX0600160583D is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, with straight-cut teeth and a 16:1 reduction ratio. It's rated for 44 N.m continuous output torque, with a maximum of 70 N.m for peak loads — so on a servo or stepper motor application, the continuous figure is what you size for, not the peak. Service life is specified at 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous running at that speed. If you push the speed or ambient temperature higher, the life shortens proportionally; the 30,000-hour figure is the baseline at the rated conditions. Efficiency sits at 94 %, which is typical for a single-stage planetary with straight teeth. The noise level is 58 dB at 1 m, no-load — quiet enough for a small machine shop floor without hearing protection, but the load profile will change that number.
Mechanical limits you need to know
The housing is black anodized aluminium, the shaft is C45 steel. The shaft output seal is rated IP54 — that's splash protection, not washdown. If your application sees directed water or dust, you'll need to shield the output side. Maximum axial force on the output shaft is 450 N at 100 rpm for the full 30,000-hour life, or 600 N if you're willing to drop to 10,000 hours. Radial force (applied mid-shaft) is 340 N for the long life, 500 N for the shorter. These are real constraints when you're coupling to a belt drive or a pinion — overshoot them and the bearing life collapses. Torsional rigidity is 2.5 N·m/arcmin, and maximum backlash is 25 arc-minutes. That's standard precision — fine for positioning conveyors or indexers, but not for a CNC axis where you need under 5 arc-min. Moment of inertia is 0.088 g·cm², which is low enough that it won't dominate the reflected inertia on a small servo loop. Mounting position is any orientation — horizontal, vertical shaft up or down — no oil-leak concerns since it's lubricated for life. The operating ambient range is -25 °C to 90 °C, so it'll handle a hot motor flange or a cold warehouse startup.
Obsolete — what that means for your BOM
Schneider Electric lists the GBX0600160583D as obsolete. For a BOM that's frozen with this part number, the only sourcing channel is independent distribution — new-old-stock or surplus. We can quote against your RFQ; availability and pricing vary by lot, so we confirm at quote time, not on the page.
