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)
NNCF design bearings have three integral flanges on the inner ring and one integral flange on the outer ring enabling the bearing to provide axial location for a shaft in one direction. A retaining ringis inserted in the outer ring at the side opposite the integral flange andserves to hold the bearing together.
