Needle Roller Bearings RNA, NK Type
RNA, NK type needle roller bearings, this type of bearing has no inner ring, it is suitable for the support structure with limited radial installation size, and the journal matched with the bearing is directly used as the rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is processed to the appropriate size and shape accuracy, the entire set of needle roller bearings can have a high life and running accuracy. At the same time, since there is no inner ring, the diameter of the shaft can also be appropriately enlarged, thereby increasing the rigidity.
