PROBLEM TO BE SOLVED: To provide a roller bearing reducing slide wear between an outer ring and a thrust bearing plate. SOLUTION: In a chain, a steel cylindrical roller 4 and a carbon impregnated ceramic cylindrical rollers 5 are incorporated between a bush functioning as an inner ring and a roller 3 functioning as the outer ring, and the thrust bearing plates 8 attached to an outer periphery of the bush(the inner ring) 2 are disposed so as to oppose to both side surfaces of the roller(the outer ring) 3. The thrust bearing plate 8 is formed by carbon impregnated ceramic having a self-lubricating property. COPYRIGHT: (C)2005,JPO&NCIPI
