Double row full complement cylindrical roller bearings Also without a cage, the second row of rollers means the design of these bearings can incorporate the maximum number of rollers, making them suitable for very heavy radial loads and increased radial stiffness. The additional row of rollers allows for the increased radial loads. The major design differences between the bearings are the configuration of the inner and outer ring flanges and the cage design and material. Double row tapered roller bearings locate the shaft in both directions with a specific axial clearance or preload. The NN design has inner ring with two flanges and outer ring without flange, and the NNU design has inner ring without flange and outer ring with double flanges. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools. Because of their second row of rollers, double row cylindrical roller bearings are suitable for heavy radial loads. Table 6 lists the radial internal clearance values of the Model SL cylindrical roller bearings.
