<P>PROBLEM TO BE SOLVED: To prevent mutual separation between inner rings by a simple structure and to reduce manufacturing costs by simplifying manufacture in a double row cylindrical roller bearing in which the inner rings in a plurality of rows are integrated by an outer ring. <P>SOLUTION: The double row cylindrical roller bearing 11 includes the integral outer ring 14 with raceway surfaces 14a, 14b of a plurality of cylindrical rollers 12, 13, and the plurality of the inner rings 15, 16 with raceway surfaces 15a, 16a of the cylindrical rollers. Contact parts 15c, 16c of the adjacent inner rings are fitted and fastened as a spigot shape in which one is concave and the other is convex, and the inner ring 15 and the inner ring 16 are fastened by a surface frictional force between a contact surface 15d of the inner ring 15 and a contact surface 16d of the inner ring 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
