Double-row full-roller self-locking cylindrical roller bearing for tile shell of seamed steel pipe forming machine

The invention discloses a double-row full-roller self-locking cylindrical roller bearing for a tile shell of a seamed steel pipe forming machine, and relates to the technical field of bearings. The invention aims to solve the problems that a bearing in a tile shell of an existing seamed steel pipe forming machine is insufficient in bearing capacity, so that the service life of the bearing is short, the maintenance period cannot be met, and meanwhile, the bearing is inconvenient to disassemble and maintain. The cylindrical roller bearing comprises a long inner ring, two outer rings and a plurality of cylindrical rollers, the outer sides of the two ends of the long inner ring are sleeved with the outer rings respectively, and the cylindrical rollers are densely arranged between the inner side walls of the outer rings and the outer side walls of the long inner ring in the circumferential direction. The invention is used for bearing bush support of the seamed steel pipe forming machine. 一种有缝钢管成型机瓦壳用双列满滚子自锁圆柱滚子轴承，
