This planetary gearbox is available through independent surplus and broker channels. Quantities are lot-specific and confirmed at RFQ — we source it against your BOM line. ## Torque and duty cycle — what the ratings mean Continuous output torque is 260 N.m (2301.2 lbf.in) at 100 rpm and 30 °C. This is the sustained load the gearbox can carry across its 30,000-hour service life without exceeding thermal limits. Maximum output torque reaches 416 N.m (3681.9 lbf.in) under the same conditions — this is the peak overload capacity for occasional starts or transient loads, not a continuous rating. Rated efficiency is 94 %, typical for a straight-tooth planetary stage at this ratio. The remaining 6 % is lost as heat in the gear mesh and bearing drag. ## Mechanical limits — shaft loads and backlash Maximum axial force Fa is 2100 N at 100 rpm for the 30,000-hour life, or 2800 N for a 10,000-hour duty cycle. Radial force Fr is 1500 N (30,000 h) or 2000 N (10,000 h), applied at mid-distance from the output shaft. These are the bearing and shaft limits — exceeding them shortens service life or causes immediate failure. Maximum torsional backlash is 12 arc.min, and torsional rigidity is 13 N.m/arcmin. The backlash figure governs positioning repeatability in indexing or servo applications — 12 arc.min is standard precision for a straight-tooth planetary, not low-backlash. ## Environmental and integration specs Shaft output sealing is IP54 — protected against dust ingress and splashing water, but not submersion. The housing is black anodized aluminium, and the shaft material is C45 steel. The gearbox is lubricated for life — no maintenance re-greasing interval. Noise level is 65 dB at 1 m, no-load. External diameter is 120 mm (4.7 in). The straight-tooth design is simpler and more efficient than helical for this size class, but runs slightly louder.","metaTitle":"Schneider Electric GBX1200120704F Planetary Gearbox, 12:1","metaDescription":"Schneider Electric GBX1200120704F planetary gearbox, 12:1 ratio, 260 N.m continuous torque, 94% efficiency, 12 arc.min backlash.
