Claims

[Scope of utility model registration request]

The roll shaft includes a roll shaft in which a plurality of divided roller attachment portions are formed eccentrically from the axis, and one cylindrical sleeve that is loosely fitted to the roll shaft through each of the divided rollers in the divided roller attachment portion. A rolling mill characterized in that, in the split reinforcing roll, thrust receiving means using ball bearings for receiving thrust force acting on the sleeve is provided on the roll shaft located at both ends of the sleeve in the axial direction. Split reinforcement roll.
