NU series cylindrical roller bearings

NU type cylindrical roller bearings have two ribs on the outer ring and no ribs on the inner ring. Within a certain range, the shaft is allowed to perform bidirectional axial displacement relative to the bearing box, that is, it can withstand the length change of the shaft caused by thermal expansion, so it is suitable as a non-locating bearing. It can bear larger radial loads, but not axial loads.
