NTN 430308U is a double row tapered roller bearing in through hardened steel, with a 40 mm bore, a 90 mm outside diameter, a 56 mm cone width and a 45.5 mm cup width. Its dynamic load rating is 157,000 N. Tapered rollers on angled raceways let one bearing carry radial load and thrust together, which is why this type is chosen for gearboxes, axles and wheel hubs where loads are heavy and space is tight. Cone and cup are separable, so the inner ring with its rollers and the outer cup are fitted on their own. Sold by Pro Gear and Transmission.
