The Timken HA590317 is a wheel bearing and hub assembly in Timken's preset, pre-greased, and pre-sealed hub unit line. This design eliminates the need for bearing adjustment, initial greasing, or seal installation at the time of service - the unit arrives ready for installation as a single assembly. Timken's preset construction holds bearing preload to factory specification from the start, reducing setup variables at the wheel end. Sold by Pro Gear and Transmission.
