Inner Ring Needle Bearings NA Series are single or double row units comprising cages and needle rollers.
Since their radial section is no greater than the diameter of the needle rollers,Needle Bearings NA Series The designs provide maximum cage strength consistent with the inherently high load ratings of Needle Roller Bearings. Accurate guidance of the needle rollers by the cage bars allows for operation at high speeds. Also available are needle roller and cage assemblies using molded.
High Precision Needle Bearings NA Series Lowest cross section among rolling bearings
In applications where less space is available, needle roller and cage assemblies offer a very compact solution.
High load carrying capacity
Due to Inner Ring Needle Bearings NA Series large number of rollers, needle roller and cage assemblies have a high load carrying capacity.
High stiffness
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
