Abstract

PURPOSE:To lengthen the life of antifriction bearing by changing periodically and cyclically the same specification of antifriction bearings among the antifriction bearings which support the both ends of a pair of rolls. CONSTITUTION:The both ends 1A, 1B, 2A, and 2B of a pair of rolls 1 and 2 for rolling are supported by the antifriction bearings 3A, 3B, 3C, and 3D of the same specification. The bearings 3A to 3D are exchanged mutually and cyclically in a Z-shaped state every a certain rolling time. Thus, the loads applying on the bearings 3A to 3D are averaged, thus lengthening the life of the bearings 3A to 3D and also keeping the performance of rolls 1 and 2 at good condition.
