Timken 302097 9 KM1 Tapered Roller Bearing Set Cup Cone

The Timken 30209 9/KM1 tapered roller bearing set is a matched single‑row metric assembly consisting of a cone (X30209M) and a cup (Y30209M). Factory‑matched to Timken mounting and preload tolerances, this cone‑and‑cup pair supports combined radial and axial loads while maintaining precise shaft positioning. With a bore of 45 mm, outside diameter of 85 mm, and an overall width of 20.75 mm, it offers high load capacity for demanding industrial gearboxes, conveyors, machine tools, electric motors, pumps, and other heavy‑duty rotating equipment. Key specs include dynamic radial load ratings of 94,800 N (C1) and 24,600 N (C90), a static radial rating of 89,000 N, e factor 0.40, K factor 1.44, an effective center location of −2.5 mm, and maximum shaft and housing fillet radii of 1.52 mm. The set includes cone X30209M and cup Y30209M; its separable design, precision‑ground raceways, and optimized internal geometry support easy installation and long service life under heavy loads.
