<P>PROBLEM TO BE SOLVED: To provide a roller bearing with an alignment ring which prevents alignment capability from decreasing by improving lubricity between the alignment ring and an outer ring, and a roll arrangement for continuously casting machine using this. <P>SOLUTION: Lubricant is supplied across all the region circumferentially and axially between an alignment ring 4 and an outer ring 2 in such a way that the lubricant is led circumferentially between the alignment ring 4 and the outer ring 2 along a first oil groove, and to axial both ends between the alignment ring 4 and the outer ring 2 along each second oil groove. Furthermore, the lubricant is made to be spread to the axial both ends between the alignment ring 4 and the outer ring 2 by making the lubricant led from a first oil channel 11 to a first oil groove 13 easily flow into a second oil groove 14 in such a way that a total cross-sectional area of hole of each first oil channel 11 is made to be greater than that of each second oil channel 12 to keep a lubricant capacity supplied from each first oil channel 11 greater than a lubricant capacity flowing into each second oil channel 12. <P>COPYRIGHT: (C)2010,JPO&INPIT |
