Bearing steel Steel needle roller bearing without shoulder with inner ring NAO20x37x16 for machine
Description of NA/NKI/RNA/NK series:
Needle roller bearings with cage without inner ring NA and NKI bearings are RNA and NK needle roller bearings without inner ring. This type of bearing has no inner ring and is suitable for supporting structures with restricted radial installation dimensions. The journal matching the bearing is used as the rolling surface directly. The shaft as the raceway surface must be hardened and ground, and only when it is processed to an appropriate size and shape accuracy, the entire set of needle bearings can have a higher life and running accuracy. At the same time, because there is no inner ring, the diameter of the shaft can be appropriately enlarged, which also increases rigidity.
