Cylindrical Roller Bearings.

• Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds. They are manufactured in several different designs, the main difference being in the configuration of the flanges.
• Types of Cylindrical Roller Bearing
• NU Design - Outer ring has two integral flanges, while inner ring had no flange.
• N Design - Inner ring has two integral flanges while outer ring has no flange.
• NJ Design - Outer ring has two integral flanges and inner ring has one integral flange.
• NUP Design - Outer ring has two integral flanges and inner ring had one integral flange & loose flange ring for both side axial locations

• Double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness. Therefore they are mainly used in machine tools, rolling mill stands, plastic calenders, grinding mills and also large gearboxes.
• The most popular are the NNU NNU AND NN design.
