Cylindrical roller bearings are separable, and it is easy to be installed and disassembled. The linear contact between cylindrical rollers and raceway make cylindrical roller bearings capable of large load, both radial and impact. Cylindrical roller bearings are suitable for high speed rotation.

According to the rows of rollers, this kind of bearings can be divided into single row, double row,

four low and various transformational structures. Cylindrical roller bearing are used in all kinds of motors, generators, gas tune machines, machine tool spindles, speed reducer, and handling machineries, while four roller bearings usually apply to rolling mills.
