Abstract
Improved B and C backing bearing assemblies and second intermediate idler rolls, characterized by greatly reduced transverse rigidity, for use in 20-high cluster mills having a 1-2-3-4 roll arrangement. On each of the B and C backing assemblies, spacers are used to provide narrow gaps between the roller bearings and the shaft eccentrics so that they do not form a rigid tube about the shafts of the B and C backing bearing assemblies. Segmented bridge elements are provided to transfer the load from the middle to each side of each roller bearing. Tie means, tying all the parts together axially (including the roller bearings the eccentrics, the bridge means and the spacing means), are provided in a form which is flexible in transverse bending. The idler roll of the second intermediate rolls constitutes a solid, rod-like, transversely flexible core, mounting a series of slightly spaced rings to form the roll body. Each ring is provided with counterbores from each of its ends so that only a short central portion of each ring contacts the core.
