The rolling line speed is high, and the accuracy of the backup roll bearings and work roll bearings is required to reach P5. The backup roll is generally lubricated by oil mist, and the work roll and intermediate roll are generally grease lubricated. The bearing load capacity is large and the impact is large. The four-row cylindrical roller bearings are interchangeable. It is roughly the same as the four-row cylindrical roller bearing of wire and bar, but the size of the inner ring raceway is remained with the amount of grinding. The bearing clearance is the clearance after grinding. After grinding, the accuracy of the rolls and rolled products can be effectively improved. Four-row tapered roller bearings for work rolls are fully sealed in many applications.
