Model NA, NKI Needle Roller Bearings With Inner Ring NKI 15/16
The inner ring has no shoulder in this bearing. For this purpose, the inner ring, outer ring, complete set of needles and cage can be mounted respectively. This bearing does not limit the axial shift of shaft and outer housing. Since the cage separates the needles so as to reduce friction. It can be used for the parts with highrotational speed.
Applications:
l Road Rollers
l Industrial Gearboxes
l Electric Motors
l Automotive Transmissions
l Pumps
l Compressors
l Industrial Fans
