The cylindrical roller bearings joined in a row have a maximum number of rollers, which allows them to withstand very high radial loads. However, they can not operate at speeds as high as the cylindrical roller skf bearings with cages. The standard range of SKF cylindrical roller bearings joined by a row consists of bearings and NCF NJG.
Roller-type NCF are equipped with two fixed shoulders on the inner ring and a shoulder fixed on the outer ring and can therefore withstand axial loads and guide the shaft axially in a sense. On the side without shoulder of the outer ring, a segment of arrest keeps the various elements bearing assembly. The axial internal indicated in the table bearings, is determined to enable rolling to resume small axial movement of the tree in relation to housing, such as those resulting from thermal expansion of the tree, for example.

Roller-type NJG belong to the wide range of sizes 23 and are intended to montages subjected to very high loads and turning at low speed. These bearings are equipped with two shoulders fixed on the outer ring and a shoulder fixed on the inner ring and can therefore withstand axial loads and guide the shaft axially in a sense. Unlike other types of bearings without cage, bearings type NJG are equipped with roller not separable. The outer ring, with both fixed and shoulders its roller, can be separated from the inner ring without the rollers are likely to fall for assembling and dismantling them are considerably easier.
