Four-row tapered roller bearings have been successfully used in configurations for rolling mills around the world at low to medium speeds. Due to its design, such bearings are capable of withstanding axial loads occurring in such applications outside of radial loads, and generally do not need thrust bearings in the bearing arrangement. This means that the roll journals can be relatively short and the bearing housings on both sides of the roll can be of the same design. Due to the design of the four-row tapered roller bearing, this bearing must be mounted as a complete bearing on the roll chock. In order to be able to change rolls quickly, such bearings must be loosely fitted on the roll journal. The disadvantage of the loose fit is that the inner ring creeps on its base under the main load conditions, which usually causes wear of the base with a lower hardness than the bearing ring. In order to reduce the influence of the loose fit to a certain extent, that is, to reduce the wear, the bearing has a spiral groove in the inner ring hole. These oil grooves feed the lubricant to the contact surfaces of the inner ring and the base. In addition, the grease-filled tank absorbs abrasive particles.
