APPLICATIONS

Cylindrical roller bearings like NUP205E are commonly used in Large and medium-sized motor, locomotives, spindle, internal combustion engines, generators, gas turbines, reducer, rolling mill, vibrating screen and lifting transportation machinery, etc..

 

Cylindrical roller bearing designs:

 

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 design 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 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.

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 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, 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.

 

Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.

 

with the absence of ribs, either the inner or outer ring will move freely so as to adjust to axial movement hence can be used as free side bearings. this enables them to absorb shaft expansion to a certain extent, relative to the housing position.

 

NU and NJ type cylindrical roller bearing produce high performance results when used as free side bearings because they possess the required characteristics for that purpose. NF type cylindrical roller bearing also supports the displacement of the axial to a certain extent in both directions and therefore can be used as a free side bearing.
