This bearing supports a rotating shaft within the threshing mechanism of a harvesting machine. It is a double-row, sealed ball bearing that carries radial and axial loads from the threshing drum or related rotating components. A worn bearing produces increased vibration and noise, which can lead to misalignment of the threshing drum and uneven crop processing. As an original component, it matches the housing bore tolerance and shaft fit specified for the assembly, eliminating the need for shimming or adapter sleeves during replacement. On installation, ensure the shaft is clean and free of burrs, and press the bearing onto the shaft using the inner ring only to avoid damaging the rolling elements.
