PROBLEM TO BE SOLVED: To provide a bearing device for a strip coiler capable of sufficiently eliminating a clearance between an inner ring, a roller and an outer ring and sufficiently preventing lowering of quality and an yield by axial vibration and whirling and a problem of breakage, etc., by an impulsive load at the time of strip cutting. SOLUTION: Outer rings 1, 2 are divided into two in the axial direction, rollers 3, 4 are respectively interposed between these divided outer rings 1, 2 and an inner ring 5, an outside diameter of the one outer ring 1 is made smaller than the other outer ring 2, and pressing force in the axial direction is given to the outer ring 1 by a spring 10 and a guide shaft 10 in a bearing device for a strip coiler having the inner ring 5 connected to a winding drum main body 13 of the strip coiler, the outer rings 1, 2 connected to a bearing housing 11 and the rollers 3, 4 interposed between the inner ring 5 and the outer rings 1, 2. |
