The Timken HA590157 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, with bearing preload already set at the factory and lubrication sealed in for the service life of the unit. That means no field adjustment, no packing, and no external sealing required at installation. Sold individually as a complete wheel bearing and hub assembly. Pro Gear and Transmission carries genuine Timken parts. Call us to confirm proper fit for your axle application before ordering.
