Product Description

Cylindrical roller bearings, also known as rolling mill bearings, belong to separable bearings. 

It is easy for people to install and dismantle. They can be classified into single row, double row and four rows cylindrical roller bearings. 

The single row cylindrical roller bearings are the most widely used ones.

 And the 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 load.

N type:

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 type:

The 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 type:

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.

NF type:

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

NUP type:

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

RN type:

No outer ring and the inner ring two integral flanges.

NN type:

NN type bearing without ribs on outer ring,there is a wall in the midel of between both sides of inner ring. 

It can make shaft relative bearing between the axial displacement generated in both directions.
