Abstract
An oil film bearing assembly rotatably supports the neck of a roll in a rolling mill. The bearing assembly comprises a housing containing a sleeve bearing and a thrust bearing. A circular lock assembly coacts with the thrust bearing to axially retain the bearing assembly on the roll neck. The lock assembly is axially received on and is rotatable into and out of mechanical interengagement with the roll neck. First bearing elements are carried by and project inwardly from the lock assembly to contact a surface of the roll neck at a first location, and second bearing elements project inwardly from the housing to contact an outer surface of the lock assembly at a second location spaced axially from the first location.
