About Cylindrical roller bearing

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 NU and NJ type cylindrical roller bearing produce high performance results when being used as a 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.
