The Timken Company 56425-20024 Tapered Roller Bearing

The Timken 56425-20024 Tapered Roller Bearing is a single-row cone bearing made from chrome steel designed to support heavy combined radial and axial loads. Its separable cone design simplifies installation and maintenance while delivering high load capacity, precise shaft alignment, and long service life in demanding industrial gearboxes, rolling mills, mining equipment, construction machinery, and power transmission systems. The cone (56425) is part of Timken’s 56000 Series and is engineered to mate with Timken cups 56650, 56650B, and 56662. Key specifications include bore 4.2500 in (107.950 mm); inner ring width 1.4375 in (36.513 mm); weight about 12.55 lb (5.69 kg); ABMA Class 2 precision; cage material stamped steel; dynamic radial load rating (C1) 50,900 lbf (226,000 N); dynamic radial load rating (C90) 13,200 lbf (58,700 N); dynamic axial load rating (Ca90) 11,200 lbf (50,000 N); static radial load rating (C0) 79,700 lbf (355,000 N); maximum shaft fillet radius 0.140 in (3.60 mm); shaft backing shoulder diameters frontface (da) 4.61 in (117 mm) and backface (db) 4.84 in (123 mm); effective center location 0.08 in (2.0 mm); geometry factor (Cg) 0.158 and K factor 1.18. Typical applications include industrial gearboxes, rolling mills, mining and aggregate equipment, construction machinery, and heavy-duty power transmission systems.
