Abstract
An oil film bearing for a roll neck in a rolling mill, comprising a bearing chock containing a bushing having a lining of babbitt metal. A sleeve is removably received on and rotationally fixed relative to the roll neck. The sleeve is journalled for rotation within and is axially shiftable with respect to the bushing. An abutment protrudes radially from an exposed outboard end of the sleeve for engagement by an outboard end face of the bushing during axial removal of the bearing from the roll neck. The lining of babbitt metal is recessed axially inwardly from the bushing outboard end face by a distance sufficient to prevent it from being damaged by engagement with the radially protruding abutment.
