 Since the rolling elements in cylindrical roller bearings make line contact with raceways,these bearings can accommodate heavy radial loads. The rollers are guided by the ribs on either the inner or outer ring, therefore these bearings are also suitable for high speed applications. Furthermore, aylindrical roller bearings are separable, and relatively easy to install and disassemble even when interference fits are required.

 Double and multiple row bearing arrangements are also available.

 NN type and NNU type available. Widely used for applications requiring thin-walled bearings, such the main shafts of machine tools, rolling machine rollers, and in printing equipment. Internal radial clearance is adjusted for the spindle of machine tools by pressing the tapered bore of the inner on a taperes shaft.
