Abstract

In a bearing assembly for a roll neck in a rolling mill, an inner seal ring is mounted with an interference fit as by shrink fitting, on an end portion of an inner bearing component, e.g., the sleeve of an oil film bearing or the inner race of a roller bearing. The end portion of the inner bearing component is suitably dimensioned and configured to deflect radially inwardly under the influence of hoop stresses developed as a result of the aforesaid interference fit, thereby causing the inner seal ring to be inclined towards the roll end face. The end portion of the inner bearing component has an outer diameter which is larger than the outer diameter of the remainder of the inner bearing component.
