Four-row Cylindrical Roller Bearing is mainly used in metallurgical equipment. It is characterized by the compact structure, high stiffness, and high load carrying capacity, so it is the most widely used among the rolling mill bearing. Because the Four-row Cylindrical Roller Bearing cannot bear the axial load, it is necessary to work with a thrust bearing to take the axial load.
This type of Bearing is separable. Its inner ring has no ribs, so its inner and outer rings can be installed or removed separately, which is easier for the bearing assembly and maintenance.
This bearing is mainly used in rolling mills with high requirements for speed and precision, e.g., wire rolling mill, section rolling mill, cold or hot plate rolling mill, or breakdown rolling mill.
Typically, a solid brass cage or a welded-pin cage is used.
