Maximum output torque hits 416 N.m at 100 rpm and 30 °C; continuous duty is rated at 260 N.m under the same conditions — that 260 N.m figure is the one to size the application around for sustained operation. Efficiency is listed at 94 %, which is typical for a single-stage planetary of this size. Noise level at 65 dB at 1 m, no-load — that's quiet enough for a lab or light assembly line without an enclosure. ## Obsolete — sourcing through independent channels Schneider Electric lists this gearbox as obsolete. The GBX1200321002F is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ. Service life is specified at 30,000 hours at 100 rpm and 30 °C, and the unit is lubricated for life — no maintenance oil changes. That 30,000-hour figure is the L10 bearing life under rated load; if the application runs 24/7, budget for replacement at roughly 3.4 years continuous. ## Mechanical limits — axial and radial loads, backlash Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour life target, or 2800 N if you accept a 10,000-hour service life. Maximum radial force Fr at mid-span on the output shaft is 1500 N for 30,000 hours, 2000 N for 10,000 hours. These are the load limits that govern bearing selection in the driven mechanism — exceed them and the service life drops faster than the derating curve suggests. Torsional rigidity is 13 N.m/arcmin, and maximum torsional backlash is 12 arc.min. For a positioning axis, that 12 arc.min of lost motion at reversal means the gearbox alone contributes about 0.2° of hysteresis — factor that into the servo tuning and position budget. ## Environmental and mounting specs Shaft output protection is IP54 — the gearbox body is sealed against dust ingress and splashing water at the shaft exit, but the motor input side depends on the motor's own IP rating. Housing is black anodized aluminium; shaft material is C45 carbon steel. The 120 mm external diameter and straight-tooth design mean this mates with the GBX series motor flanges — confirm the pilot diameter and bolt pattern against the motor before committing the BOM line.","metaTitle":"Schneider Electric GBX1200321002F Planetary Gearbox, 416 N.m","metaDescription":"Schneider Electric GBX1200321002F planetary gearbox, 32:1 ratio, 416 N.m max torque, 94% efficiency.
