Cylindrical roller bearings consist of an inner ring, an outer ring, cylindrical rollers, and a cage (some models may not have an inner or outer ring). They have the advantages of extremely high radial load capacity, good rigidity, low coefficient of friction, suitability for high speeds, and the ability to withstand a certain axial displacement. They are suitable for heavy-load, high-speed, and rigid support applications. Typical applications include large motors, machine tool spindles, gearboxes, rolling mills, and industrial pumps.
