Cylindrical roller bearings double row full complement

Double row full complement cylindrical roller bearing sincorporate a maximum number of rollers and are therefore suitable for very heavy radial loads. However, they cannot operate at the same high speeds as caged cylindrical roller bearings.Double row full complement cylindrical roller bearings are produced as standard in four designs, three open designs and one sealed. All the bearings are non-separable and have an annular groove and three lubrication holes in the outer ring to facilitate efficient lubrication.

NNCF design (Cylindrical roller bearings double row full complement)
