Brif introdutions of Bearing NU226E

The rollers in a single row cylindrical roller bearing are always guided between the integral "open" flanges on one of the rings. These "open" flanges combined with the specially designed and surface treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature.
The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings.
Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds. They are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs.

Cylindrical Roller Bearing
Description	Cylindrical roller bearings belong to separable bearings, with easy method of mounting and dismounting. They can be classified into single row, double rows and four rows. As per different rib of the ring, single-row cylindrical roller bearings can be divided into N series, NU series, NF series, NUP series and so on. Cylindrical roller bearings carry a very heavy radial loads.

These bearings are separable and are produced in several designs:

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.
