The GBX0600090553F is a 60 mm diameter planetary gearbox with straight teeth and a 9:1 reduction ratio. Continuous output torque is 44 N.m at 100 rpm and 30 °C; peak torque hits 70 N.m under the same conditions — that's the short-duration overload ceiling before the gear train yields. Efficiency sits at 94 %, which means about 6 % of input power is lost as heat in the gear mesh and bearings. For a motor driving a 44 N.m load at 900 rpm input, that's roughly 30 W of thermal dissipation inside the housing — the black anodized aluminium body handles it without forced cooling. Torsional backlash is 20 arcmin maximum — not a precision-indexing gearhead, but fine for conveyor drives, rotary tables, or positioning where the load doesn't reverse direction under torque. Torsional rigidity is 2.5 N.m/arcmin, so the windup under full continuous load is about 17.6 arcmin.
Lifecycle and sourcing — obsolete, sourced per RFQ
Schneider Electric lists the GBX0600090553F as obsolete. The gearbox is available through independent surplus and broker channels; quantities are lot-specific and confirmed at quote time. Service life is rated 30,000 hours at 100 rpm and 30 °C — that's about 3.4 years of continuous 24/7 operation before the lubricant degrades. The gearbox is lubricated for life, so no maintenance re-greasing schedule applies. Shaft output seal is IP54 — fine for dry indoor environments but not washdown. Ambient operating range is -25 to 90 °C, covering most industrial cabinet and machine-mount conditions.
