NF Type

Single-row, single rib on the outer ring, double ribs on the inner ring. NF-type cylindrical roller bearings can be used for axial positioning in one direction. If axial positioning in two directions is required, the corresponding NP-type cylindrical roller bearings can be adopted, which are bidirectional positionable bearings with a loose rib o...
