The Timken HA590515 is a hub unit bearing assembly engineered as a preset, pre-greased, and pre-sealed unit. Timken's integrated hub design combines the wheel bearing and hub into a single assembly, eliminating the need for in-field bearing adjustment, greasing, or seal installation at the wheel end. The preset bearing geometry is factory-set to Timken's specification, removing variability from the installation process. Sold individually by Pro Gear and Transmission.
