The loose rib on the outer ring allows the bearing to compensate for misalignment between the shaft and the housing, reducing the risk of premature failure due to misalignment The loose rib on the outer ring allows the bearing to compensate for misalignment between the shaft and the housing, reducing the risk of premature failure due to misalignmentnup cylindrical roller bearing. This makes NUP cylindrical roller bearings suitable for applications where shaft deflections or misalignments are common.
