100:1 planetary reduction — torque and backlash that matter
The GBX0801001401F is a straight-tooth planetary gearbox with a 100:1 reduction ratio, delivering 120 N·m continuous output torque at 100 rpm and 30 °C. Maximum output torque hits 192 N·m under the same conditions — the extra headroom handles transient overloads without immediate damage. Torsional backlash is rated at 16 arc-min maximum. For a positioning axis that cycles between directions, that 16 arc-min is the lost motion you'll see at the load — budget it into your accuracy budget if the application indexes repeatedly.
Service life, lubrication, and thermal limits
Rated service life is 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous run time before the gear train reaches its wear ceiling. The gearbox is lubricated for life, so no oil-change intervals to schedule on the PM calendar. Ambient temperature range spans -25 °C to 90 °C, which covers most indoor industrial enclosures and some outdoor cabinet applications. The IP54 rating on the shaft output means it resists dust ingress and splashing water — fine for a dry machine bay, but not washdown. Efficiency sits at 94 % — the 6 % loss is heat dumped into the housing. In a sealed cabinet with other heat sources, that thermal load adds up; the black anodized aluminium housing radiates reasonably well, but forced airflow may be needed if the duty cycle is high.
Shaft loading — axial and radial limits
Maximum axial force (Fa) is 1200 N at 100 rpm for a 10,000-hour life, dropping to 900 N for the full 30,000-hour rating. Radial force (Fr) at mid-span on the output shaft is 950 N for 10,000 hours or 650 N for 30,000 hours — the radial limit is the tighter constraint for belt or chain drives. The output shaft is C45 steel — standard medium-carbon grade with good wear resistance for keyed or clamped couplings. The 80 mm housing diameter fits a compact envelope; the straight-tooth design is noisier than helical but cheaper to produce and back-drives with less cogging.
Obsolete — sourcing reality for this planetary gearbox
Schneider Electric has marked the GBX0801001401F as obsolete. Stock is sourced through independent surplus and liquidation channels. Quantities are lot-specific — confirmed at RFQ against your BOM line. The 60 dB noise level at 1 m (no-load) is quiet enough for a lab or packaging line, but the straight-tooth whine under load will be higher.
