The cylindrical roller bearings consist of straight geometry for outer ring, inner ring and roller. The cages can be made of either polyamide, steel or even brass based on the application and utility. The inner and outer rings are separable. These bearings can accommodate high radial loads as the roller makes a line contact with the raceway. The bearings are available in a variety of designs & sizes. Different types of bearings are designated as NNU and NN for double row bearings, depending on the inner or outer flange sizes of the bearing rings.
The features and utility of the bearing will depend on the type of double row cylindrical bearing. Broadly, here are the features of each type:
NNU Type:
NN Type:
Some cylindrical bearings have no flange on either the inner or the outer ring. So the rings move axially relative to each other. These can be used as floating bearings. Cylindrical roller bearings in which either inner or outer rings have two flanges on both sides, and the other ring has one, are capable of some load in one direction. The bearings are designed for maximum load capacity. With optimised design, stress distribution is uniform and edge loading is minimised. The separable parts are interchangeable. This is particularly applicable in case of double row bearings.
Most of the advantages of a double row cylindrical roller bearing are attributed to that of all cylindrical roller bearings. However, with double rows it amplifies the benefits, such as:
