8:1 planetary — 120 N.m continuous, 192 N.m peak
The GBX1200080702F is a straight-tooth planetary gearbox with an 8:1 reduction ratio, delivering 120 N.m continuous output torque at 100 rpm (86 °F ambient) and peaking at 192 N.m for short-duration loads. The 94% efficiency means only 6% of input power is lost as heat — relevant for continuous-duty applications where thermal buildup in a sealed enclosure matters.
Backlash and positioning — 8 arc-min
Maximum torsional backlash is 8 arc-minutes — standard precision for a straight-tooth planetary. If your axis needs less than 0.13° of lost motion at reversal, this gearbox won't hold it; look at a low-backlash or helical planetary instead. The torsional rigidity of 12 N.m/arcmin tells you how much windup you get under load: at 120 N.m continuous, expect about 10 arc-min of elastic deflection on top of the backlash.
Lifecycle and sourcing — obsolete, sourced per RFQ
Schneider Electric lists this gearbox as obsolete. The 30,000-hour service life at rated load (100 rpm, 30 °C) means a used pull from a decommissioned line with verified runtime could still have significant remaining life — but you're buying on condition, not warranty. Sourced through independent distribution against an RFQ; availability and pricing confirmed at quote time.
Load ratings — axial and radial forces
Maximum axial force (Fa) is 2100 N for the full 30,000-hour life, or 2800 N if you accept a 10,000-hour service interval. Maximum radial force (Fr) is 1500 N for 30,000 hours, 2000 N for 10,000 hours — both measured at mid-span on the output shaft at 100 rpm. These are the limits for overhung loads like belt pulleys or chain sprockets; exceed them and the output bearing life drops fast.
Environmental fit — IP54, lubricated for life
Shaft output seal is IP54 — splash protection, not washdown. Fine for a dry indoor machine tool or conveyor drive; don't put it where a hose hits the output seal directly. The housing is black anodized aluminium, shaft is C45 steel. Lubricated for life — no oil-change schedule, but the grease fill is sealed at the factory and can't be replenished in the field. Operating range is -25 to 90 °C ambient, which covers most indoor industrial environments.
Noise and vibration — 65 dB at 1 m
Noise level is 65 dB at 1 m, no-load — roughly the hum of a quiet office printer. Straight-tooth gears are inherently noisier than helical at higher speeds, but at 100 rpm input (12.5 rpm output) the noise floor is low. If your application runs the input above 1000 rpm, expect the noise to rise noticeably.
