Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rollingelements. 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 suitablefor applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.

10 Physical Characteristics:
1) Cylindrical roller bearing can be separated by single row,double rows and four rows.
2) This kind of bearing can be submitted to high radial load and some axial load.
3) The rolling element of cylindrical roller bearing is cylinder,the two ends of the external lines have the corrective slope
which can eliminate the contact stress.
4) NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as millings.
