Single-row cylindrical roller bearings with cages are assemblies consisting of full inner and outer rings as well as cylindrical roller and cage assemblies. The outer rings have rigid ribs on both sides or no ribs, and the inner rings have one or two rigid ribs or are designed without ribs. The cage prevents the cylindrical rollers from coming into contact during rolling..
Cylindrical roller bearings are also available in sealed or split design. In sealed bearings, the rollers are protected from contamination, water and dust, while ensuring lubricant retention and elimination of contamination. This provides less friction and longer life. Split bearings are designed primarily for bearing assemblies that are difficult to access, such as crankshafts, where they simplify maintenance and replacement:
