The Timken HA590023 is a hub unit bearing assembly engineered as a preset, pre-greased, and pre-sealed unit. Timken builds these assemblies ready to install without field adjustment of bearing preload, eliminating a critical setup step during wheel-end service. The sealed design keeps lubrication in and contaminants out for the life of the unit. Pro Gear and Transmission carries this genuine Timken part for heavy-duty wheel-end applications.
