This tapered roller bearing supports the front axle of the host tractor, carrying both radial and axial loads from the wheel hub. It sits in the axle assembly between the hub and the spindle, maintaining proper wheel alignment and load distribution. A worn bearing produces a growling noise during turns and causes excessive hub play, which can lead to uneven tire wear and seal damage. The bearing is manufactured to the original geometry, matching the raceway angle and roller profile of the factory assembly so that preload settings remain within specification. On installation, clean the spindle and housing bore thoroughly, and torque the hub nut to the correct setting to achieve the required bearing end play.
