configuration, strong rigidity and high loading capacity; most are used on machine tool spindles. FC, FCD and FCDP four-row series can endure big axial load and are mainly used on heavy machines for example rolling mills. Cylindrical roller bearings are mostly used on kinds of industrial machines .such as motors, machine tool spindles, oil machine, rolling mills, loading and moving machine
The rollers in a single row cylindrical roller bearing are always guided between the integral "open" flanges on one of the rings. These "open" flanges combined with the specially designed and surface treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature.
