These use rollers as the rolling elements and have a high radial load capacity, which leads small frictions and high speed rotation. 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 fitted tightly. The outer rings have rigid ribs on both sides or are without ribs, the inner rings have one or two rigid ribs or are designed without ribs. One types with no ribs, either the inner or the outer ring can move freely in the axial direction, making cylindrical roller bearings ideal for use in free side bearings that absorb shaft expansion. One type with ribs, the bearing can bear a slight axial load between the roller end surfaces and the ribs.
As for the material of the cage, it is made of pressed-steel cage, bronze cage, or polyamide
