The Timken SP580311 is a hub unit bearing assembly built to Timken's preset, pre-greased, and pre-sealed specification. Because the bearing is factory-preset and arrives fully greased and sealed, there is no in-the-shop adjustment or re-packing required at installation - the unit goes on ready to run. Timken engineers these hub assemblies for driveline and axle wheel-end applications where consistent bearing preload and contamination exclusion are critical to service life. Sold individually. Call us to confirm proper fitment for your specific axle and vehicle application.
