Four-Row Cylindrical Roller Bearings
Four-row cylindrical roller bearings are bearings composed of an inner ring, an outer ring, a cage, and cylindrical rollers. According to the internal structure of the bearing, they are divided into four-row cylindrical roller bearings such as FC, FCD, FCDP, SFCD, SFCDP, and FCJ. This type of bearing has a high radial load, but cannot withstand axial force. The radial size is small, but the limit speed is high. Since the inner ring has no flange, the inner ring and the outer assembly can be installed separately. This type is mainly used in various cold and hot rolling mills where the rolling mill rolls are frequently replaced. It has the advantages of large radial load capacity, high rotation accuracy, and convenient installation and disassembly.
