PURPOSE:To prevent application of an excessive force onto a bearing by installing a bracket for holding a roller shaft in a bearing box which holds a journal attached to a cell. CONSTITUTION:A journal 32 is bolt-fixed to the edge part of a cylindrical roll cell 31, and said journal 32 is held rotatably in a bearing box 30 through a metal 33 which is inserted along the outer periphery of the journal 32. Each spherical bush 37 is inserted at both edge parts of a roll shaft 36, and installed at the edge part of a bracket 38 bolt-fixed onto the bearing box 30, and thus a roll is held in the bearing box 30 by allowing the holding center of the spherical bush 37 to nearly coincide with the holding center of the bearing box 30. |
