Cylindrical roller bearings

Cylindrical roller bearings are manufactured in many designs, dimension series and sizes.

The cage-equipped bearings are very rigid and allow high rotational speeds and high accelerations even at high radial loads.

The outer and inner rings are designed without ribs or are equipped with ribs fixed on one side / both sides. The cage prevents the cylindrical rollers from touching each other to avoid a high friction during operation. Cylindrical roller bearings with cage are more suitable for applications with high speeds than full complement cylindrical roller bearings without cage.

NKF offers cylindrical roller bearings with cage in the following series:
