Full complement roller bearings


The full complement cylindrical roller bearing has one or two raceways full of rollers and no cage, thus, it has a higher bearing capacity. Its main optional structures include NCF (single-row) and NNCF (double-row).

The full complement cylindrical roller bearing has one or two raceways full of rollers and no cage, thus, it has a higher bearing capacity. Owing that no cage guides and spaces the rollers,  the relative slide happens between rollers.  So, compared with normal cylindrical roller bearings, it is mainly applicable to low-speed cases and usually produces loud noises. 

Its main optional structures include NCF (single-row) and NNCF (double-row).

NCF Design: single-row rollers, capable of bearing single direction axial load and acting as unidirectional locating bearing.

NNCF Design: double-row rollers, capable of bearing single direction axial load and acting as  unidirectional locating bearing,applicable for low-speed and heavy load cases.

Open-type single-row and double-row full complement cylindrical roller bearings are mainly used to general mechanical equipment with low-speed and heavy-duty requirements.  Close-type double-row full complement cylindrical roller bearings are mainly used for wire rope pulleys of cranes.
