Introduction of cylindrical roller bearings

Cylindrical roller bearings mostly consist of the cage, the rollers and guided by two capped edges on a ring. It is a separable bearing, convenient for it's assembly and disassembly especially it has the advantages in a condition that the interference is required and assorted with inner ring, outer ring and housing. The bearing of this type can normally take the radial load, on the other hand, single row cylindrical roller bearing with ribbed inner ring and ribbed outer ring can take smaller axial load or intermittent axial load. The structure of the bearing showing that it runs very well under high rotational speed.

Cylindrical roller bearings with capped edge on both outer ring and inner

The NJ cylindrical roller bearing has double capped edge on outer ring and single capped edge on inner ring.
The NF cylindrical roller bearing with the single capped edge on outer ring & double capped edges on inner ring
The NJ & NF cylindrical roller bearing, the axial-displacement of the shaft or housing on one-direction can be limited. The one-direction axial positioning can be reached. It can burden smaller axial load from one-direction.
The NUP cylindrical roller bearing with double capped edges on the outer ring & with capped edge on one side of the inner ring, as well as with inner ring loose rib on the other side of the inner ring.

Cylindrical roller bearings with full complement (rollers)

Using double capped edges on the outer ring and single capped edges on the inner ring. i.e. type of NJ.V, NUP.V, RNU.V, etc. It has the advantage of great load rating and simple structure in comparison with the roller bearing which has the similar structure and has cage. In condition that rotation speed and working temperature is not high, good lubrication condition and the cleanliness of the bearing box is also relatively good then it has the first priority to use of the full complement (rollers) structure.

Full complement cylindrical roller bearing

The dimensions of E type cylindrical roller bearing are same as the dimensions of the ordinary type. But the load carrying capacity is increased accordingly due to the increasing of the diameter of rollers, the length and the number of rollers.
