120 mm planetary gearbox — 100:1 reduction, 260 N.m continuous
The GBX1201000704F is a Schneider Electric planetary gearbox with a 120 mm outer diameter and straight-cut teeth, delivering a 100:1 reduction ratio. Continuous output torque is 260 N.m at 100 rpm and 30 °C, with a maximum intermittent rating of 416 N.m at the same speed and temperature. Rated service life is 30,000 hours at 100 rpm and 30 °C, and the unit ships lubricated for life — no maintenance oil changes in the field.
Mechanical ratings and load capacity
Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 14 arc.min — this defines the positioning repeatability for indexing or servo applications where lost motion matters. Maximum axial force (Fa) on the output shaft is 2100 N at 100 rpm over the 30,000-hour service life, or 2800 N for a 10,000-hour duty cycle. Maximum radial force (Fr) applied at mid-distance on the output shaft is 1500 N for 30,000 hours, or 2000 N for 10,000 hours. Shaft output seal is rated IP54, suitable for dry indoor environments with dust and splash exposure. Ambient operating range is -25 to 90 °C.
