The Timken Company 28150 Tapered Roller Bearing Cone

The Timken 28150 tapered roller bearing cone is a single‑row cone designed to work with a matching Timken bearing cup to support combined radial and axial loads in heavy‑duty rotating equipment. Manufactured by Timken (MPN: 28150), it belongs to the 28000 series and features a bore of 1.5000 in (38.10 mm) with an inner ring width of 0.8244 in (20.940 mm). The cage is stamped steel, and the cone weighs approximately 0.9 lb (0.4 kg) when paired with the 28300 cup. Dynamic radial load ratings are C1: 16,900 lbf (75.2 kN) and C90: 4,390 lbf (19.5 kN); static radial load rating C0 is 15,500 lbf (68.9 kN), with a dynamic thrust rating (Ca90) of 3,020 lbf (13.4 kN). Maximum shaft fillet radius is 0.06 in (1.5 mm). Compatible bearing cups include Timken 28300, 28317, and other 28000‑series cups. Functionally, it provides precise shaft alignment and reliable performance under combined radial and thrust loads when used with a compatible Timken cup, making it suitable for industrial gearboxes, conveyors, mining equipment, agricultural machinery, wheel hubs, and power transmission systems in demanding environments.
