The interference fit between outer ring and bearing housing is applied to this kind of needle roller bearing without axial fixing device. Even for the condition of high load, it fully maintains bearing function either. In addition, with the large grease-storage capacity, it is unnecessary to add grease for a long-term operation.

NA and NKI type bearings without inner ring are RNA and NK type needle roller bearings. This type of bearing has no inner ring and is suitable for supporting structures with limited radial installation dimensions. The journal matched with the bearing is directly used as a rolling surface. As the shaft of the raceway surface, the hardware must be hardened and ground, and only when it is machined to the appropriate size and shape accuracy, the complete set of needle roller bearings can have a higher life and operating accuracy. At the same time, because there is no inner ring, the diameter of the shaft can also be appropriately enlarged, which also increases the rigidity.
