Timken NA484 Roller Bearing Cone

The Timken NA484 roller bearing cone is the inner-ring component of a double-row tapered roller bearing assembly (Series TNA) engineered for heavy-duty rotating equipment that must withstand combined radial and axial loads. It is commonly installed in industrial gearboxes, rolling mills, mining machinery, conveyors, and other heavy material handling systems, where precise shaft alignment and long service life are essential. Key specs: bore diameter 2.7559 in (70.000 mm); inner ring assembly width (T) 2.5626 in (65.090 mm); weight approximately 6.44 lb (2.93 kg); cage type steel; material high-grade bearing steel; design unit inch. Load ratings include dynamic radial (C1) 56,100 lbf (250,000 N), dynamic radial (C90) 8,360 lbf (37,200 N), dynamic two-row radial (C90-2) 14,600 lbf (64,700 N), and dynamic axial (Ca90) 5,500 lbf (24,500 N). Compatible cup and assembly: Timken 472D double cup; Timken NA484/472D bearing assembly. Common replacements include Timken NA484/472D bearing assembly, NA484-90016 bearing assembly, and 472D double cup.
