The Timken HA590554 is a hub unit bearing assembly designed for wheel-end service on heavy-duty applications. Timken engineers this unit as a preset, pre-greased, and pre-sealed assembly, meaning the bearing comes ready to install without field adjustment, packing, or sealing at the wheel end. That factory-set preload eliminates a common source of premature bearing failure caused by improper adjustment during service. The pre-sealed construction keeps contaminants out of the bearing from the moment of installation. Sold by Pro Gear and Transmission.
