The GBX0800160554F is a straight-tooth planetary gearbox with a 16:1 reduction ratio, 80 mm frame diameter, and 120 N.m continuous output torque at 100 rpm. That continuous torque figure — 1062.09 lbf.in — is the rating that governs steady-state sizing; the maximum output torque of 192 N.m (1699.3 lbf.in) at 100 rpm gives you the overload headroom for acceleration peaks or momentary jams, but the 30000-hour service life is calculated at the continuous rating, not the maximum. Efficiency is listed at 94 %, which means about 6 % of the input power is lost as heat inside the gearbox. For a 120 N.m output at 100 rpm (roughly 1.26 kW mechanical), that's about 75 W of heat to manage — negligible in free air, but worth accounting for if the gearbox is enclosed or mounted near temperature-sensitive components. Backlash is 14 arc.min maximum — this is a standard-precision planetary, not a zero-backlash stage. For positioning axes that reverse direction under load, that 14 arc.min of lost motion at the output translates to about 0.05 mm of linear play at a 100 mm lever arm. If the application needs tighter repeatability, this gearbox is not the right fit.
Sourcing reality — obsolete, but still specifiable
Schneider Electric has marked the GBX0800160554F as obsolete. That means the factory last-time-buy window has closed, and new units are only available through independent surplus and broker channels. For a line-down replacement or a BOM that already carries this gearbox, the practical path is sourcing from independent distribution. If you are planning a new design, look at the current GBX series catalog for an active-frame equivalent; the 80 mm frame size and 16:1 ratio are common enough that a parametric search will turn up a direct replacement from the same family.
Mechanical interface and load limits
The housing is black anodized aluminium, 80 mm external diameter, with a C45 steel output shaft. The shaft output seal is rated IP54 — splash-proof but not submersible, so keep the gearbox above the washdown zone or shield it from direct spray. Torsional rigidity is 6.5 N.m/arcmin — the gearbox twists about 0.15 arcmin per N.m of applied torque. For servo applications with high dynamic response, this stiffness figure determines the bandwidth limit of the axis; a lower rigidity number means the control loop must be tuned with lower gains to avoid oscillation. Maximum axial force on the output shaft is 1200 N for a 10000-hour life at 30 °C, derated to 900 N for the full 30000-hour service life. Radial force limits are 950 N (10000 h) and 650 N (30000 h), with the force applied at mid-span of the output shaft. These are the constraints for belt-drive or overhung-load applications — a direct-coupled load sees negligible radial force, but a belt pulley or chain sprocket will consume a significant portion of the radial budget. The gearbox is lubricated for life and sealed — no maintenance ports, no oil-change interval.
