Design types of cylindrical roller bearings    

Cylindrical roller bearing is the combination of 2 machined and polished grooved raceways (inner &outer rings), guilding a number of appropriate cylindrical rollers as the rolling elements, with a cage or full complement. This type of bearing is designed to carry heavy radial loads at high speed.

 

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.

NU designThe outer ring of bearings of the NU design has two integral flanges and the inner ring is without flanges. Axial displacement of the shaft with respect to the housing can be accommodated in both directions within the bearing itself.

NJ designThe 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.

NF design The outer ring has one integral flange and the inner ring two integral flanges.

NP design The outer ring has one integral flange and one non-integral flange in the form of a loose flange ring and the inner ring two integral flanges.

NUP designThe 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, i.e. they can provide axial location for a shaft in both directions.

RN design No outer ring and the inner ring two integral flanges.

RNU design The outer ring has two integral flanges and no inner ring.
