PROBLEM TO BE SOLVED: To provide an oil film bearing assembly for supporting freely rotatably the neck part of the roll of a rolling mill. SOLUTION: The neck part of the roll 10 of the rolling mill is supported freely rotatably. The bearing assembly includes a housing comprising a sleeve bearing 36 and a thrust bearing 34. The bearing assembly is held in the axial direction in the neck part of the roll because of interactions of an annular lock assembly 44 with the thrust bearing. The lock assembly is housed in the axial direction in the neck part of the roll, in a mechanical mutual engaged state and freely rotatable state from this engaged state. A first bearing element 66 is supported in the lock assembly, also projected inward from the lock assembly and brought into contact with the surface of the neck part of the roll in a first place. A second bearing element is projected inward from the housing and brought into contact with the outside of the lock assembly in a second place away from the first place in the axial direction.
