N design
The inner ring has two integral flanges and the outer ring is
without flanges. Axial displacement of the shaft with respect to
the housing can be accommodated in both directions within the
bearing itself. The bearings are therefore used as non-locating
bearings.
NJ design
The outer ring has two integral flanges and the inner ring one
integral flange. The bearings are therefore suitable for the axial
location of a shaft in one direction, see also under "".
NUP design
The outer ring has two integral flanges and the inner ring one
integral flange and one non-integral flange in the form of a loose
flange ring. The bearings can be used as locating bearings
