Double row full complement cylindrical roller bearings contain the largest number of rollers because they have no cage.
NNCL type
NNCF type
NNC type
NNF type sealed bearings
Bearings without cages contain the maximum number of rollers. Therefore, double row full complement cylindrical roller bearings are suitable for larger radial loads due to their second row of rollers.
The increased number of rollers increases radial stiffness.
