The Timken 42584 bearing cup outer race is a precision single-cup tapered roller bearing designed to pair with Timken cones such as 42350, 42373, or 42381 for heavy-duty industrial, automotive, agricultural, and power transmission applications. It belongs to the 42000 series and has an outside diameter of 5.8437 in (148.430 mm) and a cup width of 0.8438 in (21.433 mm), with a maximum housing fillet radius of 0.120 in (3.050 mm). The housing backing shoulder diameters are Da 5.630 in (142.000 mm) and Db 5.280 in (134.110 mm), and the geometry factor is 0.139, with a weight of 3.7 lb (1.70 kg). Made from high-carbon chromium bearing steel, this outer race is used as the outer element of a single-row tapered bearing assembly in gearboxes, transmissions, wheel hubs, axles, agricultural machinery, construction and mining equipment, and other industrial power transmission systems.
