This bearing assembly supports a rotating shaft within the threshing mechanism of a combine harvester. It mounts into the housing with six bolts and carries the radial and axial loads generated during the threshing process. A failing bearing produces audible noise and vibration at the threshing drum, which can lead to misalignment and accelerated wear on adjacent components. The INA/FAG unit is manufactured to the same internal clearance and flange geometry as the original assembly, so it seats correctly without shimming. On installation, clean the mounting face and torque the retaining bolts to the specification for the housing.
