ABSTRACT:
A roll for a mill includes a roll shaft having a tapered portion disposed intermediate opposite ends thereof. The tapered portion has an outer peripheral surface tapering axially of the roll shaft. A ring of a wear-resistant material is disposed around the tapered portion of the roll shaft. A tubular sleeve having an inner peripheral surface tapering axially thereof is press-fitted between the tapered portion of the roll shaft and the ring to retain the ring in place on the roll shaft for rotation therewith. The sleeve includes an inner groove formed in the inner peripheral surface thereof and a passageway formed therethrough. The passageway is communicated with the inner groove so that pressurized oil is supplied through the passageway into the inner groove.
