Cylindrical roller bearings use rollers as rolling elements, and therefore have a higher load capacity in comparison to same dimension ball bearing. The rollers are guided by the ribs of the inner or outer ring. The inner and outer rings can be separated to facilitate assembly, and both can be fit with shaft or housing tightly. If there are no ribs, either the inner or the outer ring can move freely in the axial direction. Cylindrical roller bearings are therefore ideal to be used as so-called “free side bearings” that absorb shaft expansion.

NBC produces four row cylindrical roller bearings in different designs and arrangements depending on the requirement of the application.

Full complement cylindrical roller bearings integrate a maximum number of rollers without the usage of any cage and are therefore suitable for very heavy radial loads. However, they cannot operate at the same high speeds as caged design cylindrical roller bearings.

Thrust bearings incorporating cylindrical rollers are available in single row, double row cylindrical roller thrust bearings are able to receive axial loads only, and have high axial rigidity which makes them well suited for heavy axial loads. Bearings with dimensions not listed in the dimension tables are also manufactured. Contact NBC for more information.

NBC manufactures double row cylindrical roller bearings with both cylindrical bore and tapered bore.
