This tapered roller bearing supports radial and axial loads in rotating assemblies within the header, front axle, and rear axle of the host machine. It maintains alignment between the shaft and housing, allowing the connected components to rotate with minimal friction. A worn bearing produces audible rumble and increased play at the shaft, which can lead to misalignment of the driven assembly. The bearing is manufactured to the same internal clearance and raceway geometry as the original, so it seats correctly in the housing without requiring additional shimming. On installation, ensure the bearing is pressed squarely onto the shaft and that the retaining nut is torqued to specification.
