Planetary gearbox, 60 mm, 9:1 reduction — what the ratings mean
The GBX0600091402F is a straight-tooth planetary gearbox from Schneider Electric's GBX series, with a 60 mm housing diameter and a 9:1 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 service life is 30,000 hours at 100 rpm and 30 °C ambient — the gearbox is lubricated for life, meaning no maintenance re-greasing interval. The 94 % efficiency figure is typical for a single-stage planetary of this ratio; the 2.5 N.m/arcmin torsional rigidity indicates a stiff drivetrain suitable for positioning applications where windup matters. Maximum torsional backlash is 20 arc.min — this is a standard-precision planetary, not a zero-backlash unit. For indexing or pick-and-place axes where repeatability is critical, a lower-backlash gearbox (typically 5–10 arc.min) would be specified instead.
Mechanical limits and mounting context
The shaft output carries an IP54 degree of protection — suitable for dry indoor environments with dust and splash exposure, but not for washdown or submerged service. The housing is black anodized aluminium; the shaft is C45 steel. Maximum axial force on the output shaft is 450 N for the full 30,000-hour life, or 600 N if the application accepts a shorter 10,000-hour life. Maximum radial force (applied at mid-shaft) is 340 N for 30,000 hours, 500 N for 10,000 hours. These limits govern bearing life — overhung loads from belt drives or pinions must be checked against these curves. The noise level is 58 dB at 1 m, no-load — audible but not intrusive in a typical machine enclosure.
Lifecycle status — obsolete, sourced through independent channels
Schneider Electric lists the GBX0600091402F as obsolete. The part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. For a BOM line that requires this exact 60 mm, 9:1, 44 N.m planetary, the only sourcing path is the secondary market. If the application allows a parametric substitute (same frame size, ratio, and torque class), a cross-reference to a current-production planetary from a different series or manufacturer would require a full mechanical and thermal review — no pin-compatible drop-in is documented.
