Planetary gearbox, 120 mm, 100:1 — torque and fit
The GBX1201001404F is a Schneider Electric planetary gearbox with straight teeth, 120 mm external diameter, and a 100:1 reduction ratio. It delivers a continuous output torque of 260 N.m (2301.2 lbf.in) at 100 rpm and 30 °C, with a maximum output torque of 416 N.m (3681.9 lbf.in) under the same conditions. Rated service life is 30,000 hours at 100 rpm and 30 °C, and the gearbox is lubricated for life — no maintenance oil changes needed in that window. Efficiency sits at 94 %, so about 6 % of input power is lost as heat through the housing.
Load ratings and mechanical limits
Torsional rigidity is 12 N.m/arcmin, and maximum torsional backlash is 14 arc.min — this defines the positioning repeatability in indexing or servo-follower applications. The shaft output carries IP54 protection, meaning it resists dust ingress and splashing water at the output seal, but the gearbox body itself is not sealed for washdown.
Lifecycle and sourcing — obsolete, sourced per RFQ
Schneider Electric lists the GBX1201001404F as obsolete. The gearbox is available through independent surplus and broker channels; quantities are lot-specific and confirmed at the time of quote.
