Timken 52400 Single Row Tapered Roller Bearing Cone

The Timken 52400 Single Row Tapered Roller Bearing Cone is a separable cone designed to support heavy combined radial and axial loads while providing precise shaft alignment in demanding industrial and mobile equipment. As part of the 52000 Series, this inch-size cone (MPN 52400) uses a stamped steel cage, with a 4.0000 in bore and 1.4219 in inner ring width, and it weighs 15.52 lb. It is commonly paired with Timken bearing cups 52618, 52618P, and 52630X and is widely used in industrial gearboxes, rolling mills, mining equipment, construction machinery, and heavy-duty power transmission systems. Key load and geometry specs include a dynamic radial load rating of 13,000 lbf (C90) and 50,200 lbf (C1), two-row ratings up to 87,500 lbf (C1) and 22,700 lbf (C90), dynamic axial Ca90 of 10,600 lbf, static radial C0 of 77,000 lbf, maximum shaft fillet radius 0.140 in, and shaft backing shoulder diameters front 4.37 in and back 4.61 in, with an effective center location of -0.02 in, geometry factor 0.152 (Cg) and K factor 1.23.
