Rated service life is 30,000 hours at 100 rpm and 30 °C, which matches the continuous torque rating; push the duty cycle harder and the life shortens proportionally. ## Backlash and stiffness for positioning Maximum torsional backlash is 12 arc.min — standard precision for a straight-tooth planetary, fine for most pick-and-place or rotary indexing but not for servo-grade positioning where you'd want ≤5 arc.min. Torsional rigidity is 13 N.m/arcmin, so the gearbox winds up about 1 arcmin per 13 N.m of applied torque before the output moves — this stiffness matters when the load reverses direction. ## Sourcing an obsolete gearbox Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible drop-in replacement from Schneider exists, so a BOM revision or adapter plate may be needed if you're replacing one in service. ## Mechanical interface and environment 120 mm outer diameter housing in black anodized aluminium, shaft output rated IP54 — fine for dry indoor environments but not washdown; the seal at the shaft exit is the weak point. Shaft material is C45 steel, rated for 2100 N axial force and 1500 N radial force at 100 rpm over the 30,000-hour life — radial load applied at mid-span on the output shaft. Operating ambient range -25 to 90 °C, lubricated for life — no maintenance port for regreasing, so the 30,000-hour service life is the replacement interval.","metaTitle":"Schneider GBX1200321004F Planetary Gearbox, 32:1","metaDescription":"Schneider Electric GBX1200321004F planetary gearbox, 120 mm diameter, 32:1 ratio, 260 N.m continuous torque at 100 rpm.
