ABSTRACT:
Keyways can be eliminated from rolling mill sleeves by undercutting the existing keyway to a generally trapezoidal cross section and preparing a corresponding keyway filler from comparable metal. The keyway filler is thicker than the keyway. The excess metal from the keyway filler is removed after the keyway filler is press fitted into the undercut keyway.
