NA, NKI Type

There is an inner ring NA.NK type needle roller bearing. Since the inner ring has no rib, the inner ring, outer ring, a full set of needle rollers and cages can be installed separately, and the axial displacement of the shaft or housing is not restricted. Since the needle rollers are separated by a cage, the friction is reduced, so it can be used in parts with high rotation speed.

Drawn Cup Needle Roller Bearings are similar to standard roller bearings except for their much smaller diameter-to-length ratio. They are a very popular bearing style due to their small cross-section (distance between ID and OD). In most cases, a hardened shaft or pin acts as the inner race. Also, rollers are kept parallel to the axis of the shaft by controlling the clearance between the rollers.

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.
