N series cylindrical roller bearings

N-type cylindrical roller bearings have two ribs on the inner ring and no ribs on the outer 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.
