This bearing is a tapered roller bearing, type 32020, installed in the rear wheel hub reduction of the host tractor. It supports the axial and radial loads transmitted from the final drive gears to the wheel hub. A worn bearing produces a low-frequency rumble and increased hub play, which can lead to uneven tire wear and eventual gear tooth damage. As an original AGCO component, the bearing is manufactured to the same internal clearance and roller geometry as the assembly it replaces, so no shimming or spacer adjustment is needed during installation. On reinstallation, clean the hub bore and apply a thin coat of grease to the bearing seat.
