limit the axial shift of shaft and housing and has high limiting rotational speed. 

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 high rotational speed.
