NSK Cylindrical roller Bearings

Brief introduction:

Cylindrical roller bearings generally consist of cages, rollers and are guided by two capped edges on a ring. It is a separable bearing and convenient to mount and dismount. Its merit is especially unique under the condition that the interference is required and assorted with inner ring, outer ring and housing. On one hand, this type of bearing can normally withstand the radial load, on the other hand, single-row cylindrical roller bearing with ribbed inner ring and outer ring can take smaller axial load or intermittent axial load, this kind of bearing has a larger carrying capacity of axial load in comparison with the deep groove ball bearing. The structure of the bearing ensures that it runs very well under high rotational speed.


Types:

1.Single-row cylindrical roller bearing including NU, NJ, NUP, N and NF


2.Double-row cylindrical roller bearing such as NNU, NN, etc.

3.Four-row cylindrical roller bearing

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.


Typical applications:
They are widely used in the large and medium-size motor, locomotive, spindle, internal combustion engine, generator, gas turbine, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc.
