Rated service life is 30,000 hours at the continuous torque rating and 100 rpm; push the load toward the maximum torque figure and the life drops proportionally — the 10,000-hour rating at 416 N.m is the design limit for intermittent duty cycles. Torsional rigidity of 13 N.m/arcmin and a maximum backlash of 12 arc.min place this gearbox in the precision class for indexing or positioning axes — the stiffness figure tells you how many arc-minutes of windup you get per N.m of load, which matters for servo-driven rotary tables or pick-and-place gantries. ## Mechanical interface and environmental limits Planetary gearbox with straight teeth, 120 mm external diameter, black anodized aluminium housing — the C45 steel output shaft accepts axial loads up to 2100 N and radial loads up to 1500 N at the mid-point, both at 100 rpm over the 30,000-hour life. Shaft output seal rated IP54 — suitable for indoor environments with dust and splash exposure, but not washdown or submerged service. Ambient operating range -25 to 90 °C covers most cabinet and floor-mounted installations. Lubricated for life — no maintenance ports or regrease intervals. The 94 % efficiency figure is the mechanical loss at rated load; the 65 dB noise level at 1 m, no-load, is the acoustic baseline before coupling to the driven load. ## Lifecycle reality — obsolete, sourced through independent channels Available through independent surplus and broker channels. No pin-compatible drop-in replacement exists from Schneider — a form-fit-function substitution would require a full mechanical review of the mounting interface, shaft dimensions, and torque curve.","metaTitle":"Schneider Electric GBX1200320551F Planetary Gearbox, 32:1","metaDescription":"Schneider Electric GBX1200320551F planetary gearbox, 32:1 ratio, 260 N.m continuous torque, 94% efficiency.
