100:1 planetary reduction with 120 N·m continuous torque
The GBX0801001002F is a straight-tooth planetary gearbox in the 80 mm diameter frame, delivering a 100:1 reduction ratio. Continuous output torque is 120 N·m at 100 rpm and 30 °C, with a maximum intermittent torque of 192 N·m at the same speed and temperature. Efficiency sits at 94 %, and the gearbox is lubricated for life — no maintenance oil changes over its 30,000-hour service life at rated load.
Torque, backlash, and shaft loading limits
Torsional backlash is rated at 16 arcmin maximum — this is a standard-precision planetary, not a zero-backlash stage. Torsional rigidity is 6.3 N·m/arcmin, which governs how much windup occurs under load before the output position settles. Maximum axial force on the output shaft is 1200 N at 100 rpm for a 10,000-hour life, derating to 900 N for the full 30,000-hour target. Radial force limits are 950 N (10,000 h) and 650 N (30,000 h), both measured at mid-span on the output shaft.
Obsolete — sourced through surplus channels
Schneider Electric lists this gearbox as obsolete. No direct successor order code is published by the manufacturer. Units are available through independent surplus and broker channels.
