Planetary gearbox for precision motion — 12:1 reduction, 44 N.m continuous
The GBX0600121401F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 60 mm outer diameter and a 12:1 reduction ratio. It delivers a continuous output torque of 44 N.m at 100 rpm, with a maximum intermittent torque of 70 N.m under the same conditions. Rated efficiency is 94 %, and the gearbox is lubricated for life, eliminating the need for periodic oil changes in service. The housing is black anodized aluminium with a shaft output rated IP54, suitable for environments where dust and splash ingress are a concern.
Load capacity and service life at rated speed
At 100 rpm and 30 °C ambient, the gearbox is rated for 30,000 hours service life. The maximum radial force Fr is 340 N when applied at mid-distance from the output shaft over that lifetime, and the maximum axial force Fa is 450 N under the same duty cycle. For shorter-duration applications, the gearbox can handle higher loads: 500 N radial and 600 N axial at 100 rpm for a 10,000-hour service life. Torsional rigidity is 2.5 N.m/arcmin, and maximum torsional backlash is 20 arc.min — a specification that matters for positioning accuracy in indexing or pick-and-place axes.
