Description:
Four-row cylindrical roller bearings are mainly used on the roll necks of hot or cold rolling mills used for forming blooms, plates, and other stock. There are many variations of the bearings: the inner and outer rings can have ribs or not, the inner ring can be in one or two pieces, the bore can be cylindrical or tapered, and other variations.
All four-row cylindrical roller bearings only support radial loads, therefore, they must be used in combination with thrust bearings such as angular contact ball bearings or tapered roller bearings.
