In the assembly process of the cold roll, the width of the bearing seats on the operation side and the transmission side is required to be ensured by polishing the lining plates, and meanwhile, the tolerance of the bearing seats on the two sides to the symmetry degree of the roll axis is required to be within a required range. If the symmetry tolerance of the bearing blocks on the two sides to the axis of the roller exceeds the required range, the axes of all roller systems of the roller are not parallel, the trend of axial relative motion among the rollers is caused, and the axial relative motion trend enables the rollers to generate axial static friction force under the action of rolling pressure, so that axial force is generated, and the bearing fails in severe cases.
