ABSTRACT:
A rolling mill roll stand comprises parallel roll shafts rotatably supported by axially spaced first and second bearings contained in parallel eccentric sleeves. The eccentric sleeves are rotatably supported in a housing and the roll shafts have cantilevered ends that project externally from one side of the housing and that are adapted to carry work rolls. Third oil film bearings are contained by the eccentric sleeves and are arranged to rotatably support the roll shafts at intermediate locations between and spaced axially from both the first and second bearings.
