(2) Four-row cylindrical roller bearing + thrust bearing, the inner diameter of the cylindrical roller bearing is tightly matched with the roller neck, and it can bear radial force. It has large load capacity, high limit speed, high precision, and the inner and outer rings can be separated and can be mutually The advantages of easy replacement, easy processing, low production cost, convenient installation and disassembly, etc.; thrust bearing bearing axial force, the specific structure type can be selected according to the characteristics of the rolling mill. At heavy load and low speed, it is equipped with a thrust roller bearing to withstand the thrust load with a small axial clearance. When the rolling speed is high, it is equipped with angular contact ball bearings, which not only has high speed limit, but also can control the axial play during operation. The rolls are tightly axially guided and can withstand typical axial load forces. This type of bearing configuration not only has long bearing life, high reliability, but also has many advantages such as high precision and easy control of rolling products. Therefore, it is currently the most widely used, and is widely used in wire rod mills, sheet mills, foil mills, and double support rolls. Support rolls for rolling mill cold rolling mills and hot rolling mills.
(3) Four-row tapered roller bearings. Tapered roller bearings can withstand both radial and axial forces. There is no need to configure thrust bearings, so the mainframe is more compact. The inner diameter of the tapered roller bearing is loosely matched with the roll neck. It is very convenient to install and disassemble, but sometimes it will cause sliding creep due to the loose fit. Therefore, the inner diameter is often processed with a spiral oil groove. This type of configuration is still widely used, such as the work rolls of four-high hot rolling mills and cold rolling mills, such as work rolls, blanking machines, and steel beam rolling mills.
