60:1 planetary reduction, 260 N.m continuous
The GBX1200601402F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 60:1 reduction ratio and 120 mm outer diameter. It delivers 260 N.m continuous output torque at 100 rpm and 30 °C, with a peak capability of 416 N.m under the same conditions. Rated efficiency is 94 %, meaning about 6 % of input power is lost as heat through the gear train — a reasonable figure for a planetary stage at this ratio.
Backlash, stiffness, and load limits
Maximum torsional backlash is 14 arc-min, which sets the positioning repeatability floor for indexing or servo applications. Torsional rigidity is 12 N.m/arcmin, giving a measure of how much the output shaft twists under load. Maximum radial force Fr is 1500 N at 100 rpm for a 30000-hour life, or 2000 N for a 10000-hour life, both applied at mid-distance from the output shaft. Maximum axial force Fa is 2100 N for 30000 hours, 2800 N for 10000 hours. Overhung loads beyond these limits will shorten bearing life.
Lifecycle and sourcing — obsolete, quoted to order
Schneider Electric lists the GBX1200601402F as obsolete. Service life is rated at 30000 hours at 100 rpm and 30 °C — a solid baseline for continuous-duty applications. The gearbox is lubricated for life, so no periodic oil changes are needed.
Environmental and mechanical specs
Shaft output protection is IP54, meaning it's sealed against dust ingress and splashing water — suitable for factory floor environments with occasional washdown but not submersion. Housing is black anodized aluminium; shaft material is C45 carbon steel. Noise level at 1 m under no-load conditions is 65 dB — roughly the level of a normal conversation, acceptable for most industrial settings.
