Timken 32220M-9KM1 Tapered Roller Bearing Assembly

The Timken 32220M-9KM1 is a matched single-row metric tapered roller bearing assembly (cone X32220M and cup Y32220M) factory-matched to standard Class K precision, with the 9KM1 suffix indicating a matched set that does not alter the bearing’s dimensions or load characteristics. This separable cone-and-cup design supports combined radial and axial loads while maintaining precise shaft alignment, making it suitable for industrial gearboxes, conveyors, axle assemblies, mining equipment, heavy construction machinery, steel processing equipment, and other heavy-duty rotating machinery. Key specifications include bore 100 mm, outside diameter 180 mm, overall width 49 mm, cone width 46 mm, cup width 39 mm, weight about 5.0 kg; cage material is pressed steel and bearing material is through-hardened steel, with dynamic radial load rating C1 368,000 N (82,700 lbf), dynamic radial rating C90 95,400 N (21,400 lbf), static radial rating C0 476,000 N (107,000 lbf), dynamic axial rating Ca90 68,400 N (15,400 lbf), and geometry factors e 0.42, K 1.39, Y 1.43, Cg 0.10.
