Torque envelope and duty cycle
The GBX0800200702D: Continuous output torque is 120 N.m; the maximum output torque reaches 192 N.m — the 60% headroom covers acceleration peaks and occasional overloads, but sustained operation above the continuous rating shortens the 30,000-hour service life at 100 rpm and 30 °C. The 20:1 reduction ratio is fixed — no field-swappable stages. That makes it a drop-in replacement for a BOM position that already expects that ratio; any ratio change means a different GBX frame size.
Backlash and positioning accuracy
Maximum torsional backlash is 17 arcmin — that is a standard-precision planetary, not a zero-backlash stage. For indexing or pick-and-place where cumulative error matters, budget the full 17 arcmin at the output; the torsional rigidity of 6.5 N.m/arcmin means the gear train winds up measurably under load before the output moves.
Environmental limits and mounting
Shaft output sealing is IP54 — splash-resistant but not washdown-rated. The housing is black anodized aluminium; shaft material is C45 steel. Operating ambient range is -25 to 90 °C, and the gearbox can be mounted in any position, which simplifies panel layout. Lubricated for life — no maintenance oil changes. That saves a PM line item but also means the 30,000-hour service life at rated load is the hard replacement trigger; there is no re-greasing interval to extend it.
Sourcing reality — obsolete, quoted to order
Schneider Electric lists this GBX0800200702D as obsolete. Sourcing runs through independent surplus and new-old-stock channels; quantities are lot-specific and confirmed at RFQ. If your line-down spare is this exact gearbox, the procurement lead time depends on what the broker network holds — no factory replenishment available.
