60 mm planetary gearbox — 12:1 reduction, 44 N.m continuous
The GBX0600120551F is a 60 mm-diameter planetary gearbox with straight teeth, delivering a 12:1 reduction ratio. Continuous output torque is 44 N.m (389.4 lbf.in) at 100 rpm and 30 °C; maximum intermittent torque reaches 70 N.m (619.6 lbf.in) under the same conditions. Rated service life is 30,000 hours at rated load, speed, and ambient temperature. The gearbox is lubricated for life — no maintenance oil changes during the service window. Maximum torsional backlash is 20 arc.min, suitable for positioning axes where repeatability within that angular window is acceptable. Torsional rigidity is 2.5 N.m/arcmin.
Load ratings and environmental limits
Maximum axial force on the output shaft is 450 N for the 30,000-hour service life, or 600 N for a 10,000-hour duty cycle. Maximum radial force (applied at mid-shaft) is 340 N for the 30,000-hour life, or 500 N for 10,000 hours. The shaft output seal carries an IP54 ingress protection rating — suitable for dry indoor environments with dust and splash exposure, but not for washdown or submersion. Efficiency is listed at 94 %, and noise level at 58 dB at 1 m under no-load conditions. The housing is black anodized aluminium; the shaft material is C45 steel.
Lifecycle reality — obsolete, sourced through independent channels
The GBX0600120551F is marked as obsolete by Schneider Electric. No official successor or cross-reference is recorded in the manufacturer's lifecycle documentation. This part is available through independent surplus and broker channels.
