Needle Roller Bearings F Series
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.
