Welcome to Shandong Xinsaiyuan Bearing Co., Ltd.
Needle Roller Bearings 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.
