That continuous rating is the number to size against — the maximum output torque of 416 N.m is a short-duration peak, not a steady load. Straight-tooth planetary design, 120 mm housing diameter, black anodized aluminium body with C45 steel shaft. ## Lifecycle reality — obsolete, sourced through surplus channels Schneider Electric lists the GBX1201000551F as obsolete. This part is available through independent surplus and broker channels — quantities are lot-specific and confirmed at RFQ time. For a line-down situation or a BOM that already carries this gearbox, the 30,000-hour service life at 100 rpm and 30 °C ambient gives a planning window. The gearbox is lubricated for life — no field re-greasing interval to track. ## Load ratings and mechanical limits — the numbers that govern fit Rated axial force Fa is 2100 N at 100 rpm for the 30,000-hour life target, or 2800 N for a 10,000-hour duty cycle. Radial force Fr at mid-span on the output shaft is 1500 N for the longer life, 2000 N for the shorter. These are the limits that determine whether the gearbox survives in an overhung-load application like a belt drive or a pinion. Torsional rigidity is 12 N.m/arcmin — that stiffness figure matters for positioning accuracy in indexing or servo-follower applications. Maximum torsional backlash is 14 arc.min, which is standard precision for a straight-tooth planetary, not a zero-backlash unit. Efficiency is listed at 94 %, which is typical for a single-stage planetary at this ratio. Noise level is 65 dB at 1 m, no-load — audible but not intrusive in a machine-tool or conveyor environment.","metaTitle":"Schneider Electric GBX1201000551F Planetary Gearbox, 100:1","metaDescription":"Schneider Electric GBX1201000551F planetary gearbox, 100:1 ratio, 260 N.m continuous torque, 94% efficiency.
