Planetary gearbox, 120 mm frame, 8:1 reduction — what the ratings mean
The GBX1200081404F is a straight-tooth planetary gearbox in a 120 mm diameter housing, delivering an 8:1 reduction ratio. Continuous output torque is 120 N.m at 100 rpm and 30 °C, with a peak capability of 192 N.m under the same conditions. Efficiency is listed at 94 % — that's the power you keep after the reduction stage, not counting motor losses. Noise level at 65 dB measured 1 m away under no-load is typical for a planetary stage of this size; the straight-cut teeth are inherently noisier than helical but carry higher torque density for the same envelope. Service life is rated 30,000 hours at 100 rpm and 30 °C — the lubricant is sealed for life, so no maintenance schedule for oil changes. The shaft output carries an IP54 ingress rating, meaning it resists dust and splashing water but isn't suited for washdown environments.
Load ratings and mechanical limits
Maximum axial force on the output shaft is 2100 N for the full 30,000-hour life, or 2800 N if you accept a shorter 10,000-hour service interval. Radial force limits are 1500 N and 2000 N respectively, with the load applied at mid-distance from the output shaft. Torsional rigidity is 12 N.m/arcmin — this tells you how much the gear train winds up under load. Maximum torsional backlash is 8 arc.min, which is standard for a commercial planetary stage; if your application needs tighter positioning repeatability, you'd look at a reduced-backlash variant. The housing is black anodized aluminium, the shaft is C45 steel. Ambient operating range spans -25 to 90 °C, which covers most indoor industrial environments.
Obsolete — sourcing through independent channels
Schneider Electric lists the GBX1200081404F as obsolete. This part is available through independent surplus and broker channels. Quantities are confirmed at RFQ; the lubricated-for-life design means a low-hours pull from a decommissioned line often carries most of its 30,000-hour service life.
