NTN 30321 is a single row tapered roller bearing in through hardened steel, sold as a cone and cup set. It measures 105 mm bore (ID) by 225 mm outside diameter, with an overall width of 53.5 mm, a cone width of 49.000 mm and a cup width of 41.000 mm, and carries a dynamic load rating of 435,000 N. The tapered contact angle lets the bearing take radial and axial load at the same time, and the cone and cup separate so each half is installed on its own. Bearings like this are normally set in opposed pairs with a controlled preload to remove play. A genuine NTN part from Pro Gear and Transmission.
