The Timken SET321 is a tapered roller bearing cone and cup assembly, sold as a matched set containing components 25877 and 25820. Tapered roller bearings handle both radial and axial thrust loads, making them a standard choice for wheel-end and driveline axle applications in heavy-duty trucks. The set measures 2.9 inches in diameter and 1 inch in height. Buying the cone and cup together as a matched Timken set ensures proper contact geometry between the two mating components.
