The NTN 9380/9321 is a single row tapered roller bearing set, a matched cone and cup made of case carburized steel. It has a 3.0000 in. bore and a 6.7500 in. outside diameter, with an overall width of 1.9375 in. split into a 1.8125 in. cone width and a 1.2500 in. cup width. The dynamic load rating is 63,500 lbf. Tapered roller bearings run conical rollers on matching conical races, so one set carries radial load and thrust together, which is why they are the usual choice in wheel ends and other heavy-duty rotating assemblies. Correct adjustment and good lubrication are what keep them in service. A genuine NTN part from Pro Gear and Transmission.
