Timken 52400 Class 3 Tapered Roller Bearing Cone

The Timken 52400 Class 3 Tapered Roller Bearing Cone is a precision single-row cone engineered to support heavy combined radial and axial loads while maintaining accurate shaft alignment in demanding industrial applications. Designed for Timken’s 52000 Series in inch design, it features a 4.0000 in bore (101.600 mm) and a 1.4219 in inner ring width (36.116 mm), with a stamped-steel cage and a weight of 15.52 lb (7.04 kg). It carries dynamic radial load ratings of C90 13,000 lbf (57,900 N) and C1 50,200 lbf (223,000 N), with two-row ratings C1 87,500 lbf (389,000 N) and C90 22,700 lbf (101,000 N), plus Ca90 10,600 lbf (47,100 N) and C0 77,000 lbf (343,000 N); it is commonly paired with Timken cups 52618, 52618P, or 52630X for rolling mills, industrial gearboxes, mining equipment, construction machinery, and other heavy-duty power transmission systems. Additional design details include a maximum shaft fillet radius of 0.140 in (3.600 mm), backing shoulder diameters da 4.37 in (111 mm) and db 4.61 in (117 mm), an effective center location of -0.02 in (-0.5 mm), geometry factor Cg 0.152, and K factor 1.23.
