The Timken HA590156K is a hub unit bearing assembly designed as a preset, pre-greased, and pre-sealed unit. Timken engineers these hub assemblies to arrive ready for installation, eliminating the need for field adjustment, packing, or sealing during the install process. The preset bearing configuration removes end-play guesswork, which matters in a commercial vehicle wheel-end environment where bearing adjustment errors lead to premature failure. This genuine Timken part is sold by Pro Gear and Transmission. Call us to confirm proper fit for your specific axle application.
