Timken 28584 B79 Tapered Roller Bearing Cone Assembly

The Timken 28584 B79 tapered roller bearing cone is a single‑row cone designed to pair with compatible Timken bearing cups to support combined radial and axial loads in heavy‑duty rotating equipment. The B79 suffix is a manufacturing or batch identifier and does not alter the bearing's dimensional or performance specifications. It features a 2-1/16 in bore and 1 in cone width, with a stamped steel cage and precision‑ground raceways to deliver reliable load handling. It is commonly used with Timken cups such as 28520, 28521, 28521‑B, or other compatible 28500‑series cups depending on the application, in industrial gearboxes, conveyor drives, mining machinery, agricultural equipment, wheel hubs, and power transmission systems requiring precise shaft alignment and high load capacity. Technical specs include bore 2.0625 in (52.388 mm), inner ring width 1.0000 in (25.400 mm); dynamic radial load rating C1 22,200 lbf (98.9 kN); dynamic radial load rating C90 5,770 lbf (25.7 kN); static radial load rating C0 29,200 lbf (130 kN); dynamic thrust rating Ca90 3,720 lbf (16.6 kN); K factor 1.55; geometry factor Cg 0.0912; effective center location −0.19 in (−4.8 mm); maximum shaft fillet radius 0.14 in (3.60 mm); weight 1.7 lb (0.8 kg).
