Abstract
A sleeved roll generally has a bendable arbor. The sleeve is shrunk-fit on the arbor such that the dimensional difference between the arbor diameter and the sleeve inner diameter varies along the arbor axis. Thus the radial stresses induced by the shrunk-fit vary along the axis of the arbor. The sleeved bendable roll may be employed as a work roll or as a backup roll in a rolling mill. The roll is assembled by providing a bendable arbor having an axial surface and a hollow sleeve, axially contouring at least a portion of the arbor surface or the sleeve inner surface, positioning the hollow sleeve having an inner surface adjacent the arbor, and then shrink-fitting the sleeve inner surface on the axially convexly contoured surface of the arbor.
