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.
