Cylindrical roller bearings are typically categorized by their design, denoted by specific series designations. Common series include:

N Series: Unica fila, inner ring has two flanges, outer ring has no flanges.

NU Series: Unica fila, outer ring has two flanges, inner ring has no flanges.

NJ Series: Unica fila, outer ring has two flanges, inner ring has one flange.

NUP Series: Unica fila, outer ring has two flanges, inner ring has one flange and a loose flange ring.

NF Series: Unica fila, outer ring has one flange, inner ring has two flanges.

NN Series: Double row, used for applications requiring high radial load capacity.

NNU Series: Double row, used for high radial load applications with greater rigidity.
