This bearing supports a rotating shaft within the threshing mechanism of a combine harvester. It is a spherical roller bearing with a sealed design, intended to accommodate misalignment between the shaft and the housing. The bearing sits in the threshing drum or related assembly, allowing the shaft to rotate freely under load while maintaining its radial and axial position. Wear in this bearing produces increased vibration and noise from the threshing area, and can lead to shaft scoring if not addressed. The manufacturer produces this bearing to the same internal clearance and seal geometry as the original component, so it fits the existing housing bore without modification. On installation, ensure the bearing is pressed squarely onto the shaft and that the locking collar is seated properly.
