Cylindrical roller bearings mostly consist of the cage, the rollers and guided by two capped edges on a ring. It is a separable bearing, convenient for it’s assembly and disassembly especially it has the advantages in a condition that the interference is required and assorted with inner ring, outer ring and housing. The bearing of this type can normally take the radial load, on the other hand, single row cylindrical roller bearing with ribbed inner ring and ribbed outer ring can take smaller axial load or intermittent axial load, this kind of bearing has a larger carrying capacity of axial load compare with the deep-grooves ball bearing. The structure of the bearing showing that it runs very well under high rotational speed.

Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations. This geometry results in low friction and allows for high-speed applications. Cylindrical roller bearings are commonly available in precision grades,a classification from the Roller Bearing Engineers Committee.

Most cylindrical roller bearings are made of alloy steels or low-carbon steels. Some applications require the use of case-hardened or thorough-hardened, high-carbon, bearing-quality steel. High-carbon grades of steel do not require carburizing and can be case-hardened by induction heating or thorough-hardened by conventional heating methods. When low-carbon, carburized grades of steel are used, carbon is introduced after the cylindrical roller bearings are machined to a depth sufficient to produce a hardened case that can sustain bearing loads. The addition of carbon and alloys ensures the proper combination of a hard, fatigue-resistant case and a tough, ductile core.
