The continuous output torque is 120 N.m at 100 rpm; the maximum intermittent torque hits 192 N.m at the same speed. That 60% headroom matters when the load has short-duration peaks during acceleration or reversing — the gearbox can handle them, just not continuously. Efficiency is 94 %, which is typical for a single-stage planetary at this ratio. The 6% loss shows up as heat in the gearbox body — at full load, that's about 7.7 W thermal dissipation. In a confined enclosure, that heat needs somewhere to go; the black anodized aluminium housing radiates it, but don't bury it against a panel wall without airflow. Noise level is 60 dB at 1 m, no-load. That's quieter than a typical conveyor drive under load — about the hum of a small office printer. For a machine running in an occupied space, this gearbox won't be the noise problem. ## Obsolete — sourcing through independent channels Schneider Electric lists this gearbox as obsolete. If you're planning a replacement, the functional spec to match is the 80 mm frame, 12:1 ratio, and 120 N.m continuous torque at the output shaft. The straight-tooth planetary construction and the IP54 shaft seal are also constraints — a helical or right-angle box won't drop in without a mounting rework. Service life is rated 30,000 hours at 100 rpm and 30 °C ambient — that's about 3.4 years of continuous running. The gearbox is lubricated for life, so there's no oil-change interval to track. The IP54 shaft output seal means it's protected against dust ingress and water splash, but not pressurized washdown. ## Shaft loading and environmental limits Maximum axial force on the output shaft is 1200 N for a 10,000-hour life, dropping to 900 N for the full 30,000-hour rating — both at 100 rpm and 30 °C. Radial force limits are 950 N (10,000 h) and 650 N (30,000 h), applied at mid-span on the output shaft. If your application overhangs a sprocket or pulley beyond mid-shaft, the radial capacity drops further. Torsional rigidity is 6.5 N.m/arcmin — that's the stiffness of the gear train. For a positioning application, the total backlash is up to 14 arcmin, which is typical for a commercial planetary at this price point. That's fine for indexing or conveyor positioning; not suitable for a servo axis without a separate preload or dual-motor anti-backlash scheme.","metaTitle":"Schneider GBX0800120554F Planetary Gearbox, 12:1, 120 N.m","metaDescription":"Schneider Electric GBX0800120554F planetary gearbox, 80 mm, 12:1 ratio, 120 N.m continuous torque, 94% efficiency.
