Planetary gearbox — 12:1 reduction, 44 N.m continuous
The GBX0600121002F is a 60 mm-diameter planetary gearbox from Schneider Electric's GBX series, offering a 12:1 reduction ratio with straight-cut teeth. It delivers a continuous output torque of 44 N.m at 100 rpm and 30 °C, 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.
Load ratings and service life
Maximum radial force at mid-span on the output shaft is 340 N for a 30,000-hour life at 100 rpm and 30 °C, or 500 N for a 10,000-hour life. Maximum axial force is 450 N for the longer life target, 600 N for the shorter. Torsional backlash is rated at a maximum of 20 arc.min, and torsional rigidity is 2.5 N.m/arcmin — figures that matter for positioning accuracy in indexing or pick-and-place applications. The housing is black anodized aluminium; the output shaft is C45 steel. Shaft output sealing meets IP54, suitable for dry indoor environments but not for washdown.
Lifecycle status — obsolete, sourced through independent channels
