Timken 495A Single Row Tapered Roller Bearing Cone

The Timken 495A is a single‑row tapered roller bearing cone (TS) engineered to support combined radial and axial loads in heavy‑duty rotating equipment. Designed to mate with Timken 493A or 493D bearing cups, this cone is part of the 495 series and features a stamped‑steel cage with a 3.000 in (76.200 mm) bore and 1.1720 in (29.769 mm) inner ring width. Key ratings include a dynamic radial load (C90) of 9,000 lbf (40,000 N), a dynamic radial load (C1) of 34,700 lbf (154,000 N), and a dynamic axial load (Ca90) of 6,850 lbf (30,500 N) alongside a static radial load (C0) of 48,600 lbf (216,000 N); weight is 3.8 lb (1.7 kg). It also lists a maximum shaft fillet radius of 0.140 in (3.600 mm), shaft backing shoulder diameters da 3.39 in (86 mm) and db 3.62 in (92 mm), an effective center location of -0.03 in (-0.8 mm), and geometry factors K 1.31, ISO e 0.44, Cg 0.125. Typical applications span industrial gearboxes, rolling mills, mining equipment, construction machinery, and other heavy‑duty power transmission systems requiring high load capacity and precise load distribution. Common replacements include SKF equivalents and Timken 493A bearing cup.
