618/500M bearings made by FV are widely used in rolling mills

Apr 02, 2022

Because of the heavy loads, 4-CRB type, four-row cylindrical roller bearings are normally used. The bearing inner races are heat shrink fitted onto the rollneck and will remain with the rolls. The diameter under the rollers is held very precisely to insure that they can be used interchangeably with all inner rings. The inner races have FV specially designed chamfers to assist in the easy installation of the chocks to the workrolls. The high axial forces are countered by a steep angle tapered roller thrust bearing, TDI type. This is mounted in the operator side chock. A large diameter ball bearing, FV 60xx ,618xx, 619xx or B type, is mounted in the drive side and unitizes the chock to the workroll.

Four-row cylindrical roller bearings, 4-CRB Type, provide an excellent combination of high load capacity, high speed capability and high running accuracy. The inner rings are tight fitted on the shaft and are interchangeable from one bearing to another. A pair of large angular contact ball bearings,  in the operator side chock support thrust loads while a single ball bearing (60xx , 618xx , 619xx and etc.) maintains the axial relationship between the drive side chock and the roll.

Four-row cylindrical roller bearings, 4-row cylindrical roller bearing type, provide high load capacity necessary to support rolling loads while maintaining good accuracy. The inner rings are tight fitted to the rolls and are interchangeable from one bearing to another. A two-row tapered roller thrust bearing supports axial loads and a large ball bearing unitizes the drive side chock.
