The Timken HA590502 is a wheel bearing and hub unit assembly from Timken's preset, pre-greased, and pre-sealed hub line. This design eliminates the need for field adjustment, greasing, or seal installation during installation - the unit arrives ready to mount as a complete assembly. Timken hub units are commonly used in heavy-duty truck wheel-end applications where a self-contained bearing solution is specified. For fitment confirmation on your specific axle or vehicle, give Pro Gear and Transmission a call before ordering.
