This tapered roller bearing supports the rotating shaft inside the front axle of the host tractor. It handles combined radial and axial loads from the drive train, maintaining proper gear mesh and wheel-end alignment. A worn bearing produces a low rumble that increases with speed and leads to axle-side play. As an original AGCO component, its raceway geometry and internal clearance match the original assembly’s preload specification, so no shimming or spacer adjustment is needed during replacement. On installation, clean the housing bore and shaft journal, apply fresh grease, and torque the retaining nut to the manufacturer’s specification.
