The GBX0800160701D is an 80 mm-frame planetary gearbox from the Schneider GBX series, delivering a 16:1 reduction ratio. The continuous output torque is 120 N.m, with a maximum burst of 192 N.m — the continuous figure is the one to size the motor and load against; the peak handles transient overloads like acceleration spikes or momentary stalls. Straight-tooth gearing (not helical) means slightly higher noise at 60 dB at 1 m, no-load, but lower cost and zero axial thrust on the bearings. The 94 % efficiency is typical for a single-stage planetary; the 2.5 kW-ish thermal limit at that efficiency keeps the gearbox within its 30,000-hour service life at 100 rpm and 30 °C ambient.
Load limits — axial, radial, and the torque envelope
Maximum axial force Fa is 1200 N at 100 rpm for a 10,000-hour life, derating to 900 N for the full 30,000-hour service. Radial force Fr at mid-shaft is 950 N at 100 rpm for 10,000 hours, dropping to 650 N for 30,000 hours. These govern the bearing selection on the driven component — a belt-drive or pinion applying the full 650 N radial load will hit the 30,000-hour target; anything above that shortens life proportionally. Torsional rigidity is 6.5 N.m/arcmin — stiff enough for most positioning axes; the 17 arcmin maximum backlash (unloaded) means this is not a zero-backlash gearbox for precision servo indexers. For applications needing tighter positioning, plan a backlash-compensation routine or step up to a preloaded planetary.
Mounting and environment — what fits where
Mounts in any position — vertical, horizontal, or inverted — since the gearbox is lubricated for life with no oil-level constraint. Ambient operating range is -25 to 90 °C. The C45 steel output shaft is standard medium-carbon steel — fine for keyed or clamping connections in clean environments, but not stainless. If the application runs in a food, marine, or corrosive area, the shaft will need a coating or a stainless alternative.
Obsolete — sourcing reality for the GBX0800160701D
Schneider Electric lists the GBX0800160701D as obsolete. No direct-replacement order code is published. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a new design, consider the current GBX series frame sizes; the 80 mm frame and 16:1 ratio remain common, so a parametric match to an active catalog number is feasible with a BOM review.
