The Timken SP620303 is a wheel bearing and hub assembly engineered to Timken's preset, pre-greased, and pre-sealed specification. Because the bearing is factory-preset and the unit arrives fully greased and sealed, installation does not require manual bearing adjustment, field greasing, or setting bearing end-play at the wheel end. This design eliminates several steps that introduce variability during service. Sold individually by Pro Gear and Transmission. Call us to confirm proper fitment for your application.

Preset bearing - no field adjustment of bearing end-play required
