This deep-groove ball bearing supports a rotating shaft within the threshing unit of a grain harvester. It is a single-row, double-sealed (2RS) unit that retains factory lubrication and excludes contaminants. The bearing is installed in the shaker mechanism, where it maintains alignment of the oscillating components that separate grain from material other than grain. A worn or seized bearing introduces excessive clearance in the shaker assembly, leading to vibration, misalignment, and reduced separation efficiency. As an SKF-manufactured component, the bearing is ground to the same internal clearance and raceway geometry as the original part, ensuring correct radial load distribution without requiring selective shimming. On installation, verify the shaft and housing bores are clean and free of burrs.
