Obsolete — what that means for your BOM line
Schneider Electric lists the GBX1600120704F as obsolete. This part is sourced through independent distribution channels.
Torque ratings that matter for motor sizing
The continuous output torque is 800 N.m (7080.6 lbf.in) at 100 rpm and 30 °C ambient — this is the rating you size the driven load against for sustained duty. Maximum output torque reaches 1280 N.m (11328.9 lbf.in) under the same conditions — this covers peak loads during acceleration or momentary overload, but the gearbox should not run continuously at this level. Both torque ratings are tied to the 12:1 reduction ratio — the input motor torque is multiplied by 12, minus the 94 % efficiency loss, so the motor-side torque requirement is roughly 800 / (12 × 0.94) ≈ 71 N.m at the input for continuous duty.
Mechanical constraints — shaft loads and backlash
Maximum axial force on the output shaft is 6000 N for the 30000-hour service life at 100 rpm and 30 °C, and can be pushed to 8000 N if you accept a reduced 10000-hour life. Maximum radial force applied at mid-shaft is 4200 N for the full 30000-hour life, or 6000 N for the 10000-hour case — these limits protect the output bearings from premature failure. Maximum torsional backlash is 10 arc.min — this sets the positioning repeatability floor for indexing or servo applications. If your application needs tighter angular accuracy, this gearbox may not hold position within a few arc-minutes of a commanded stop.
Service life and environmental sealing
Rated service life is 30000 hours at 100 rpm and 30 °C — that is about 3.4 years of continuous operation. The gearbox is lubricated for life, so no oil changes or regreasing intervals are needed within that window. Shaft output sealing is IP54 — dust-protected and splash-resistant, but not rated for washdown or submersion. The housing is black anodized aluminium, and the shaft material is C45 steel.
Acoustic and efficiency profile
Efficiency is 94 % at rated load — about 6 % of input power is lost as heat in the gear mesh and bearings. For a continuous 800 N.m output at 100 rpm (roughly 8.4 kW output), the heat dissipation is about 0.5 kW, which the aluminium housing sheds without forced cooling in most panel or machine-mounted positions. Noise level is 70 dB at 1 m under no-load conditions — roughly the sound of a vacuum cleaner at conversational distance. Under load the noise will rise, but the straight-tooth planetary design is inherently louder than helical; if acoustic limits are tight, a helical gearbox would be quieter.
