Needle roller bearings with cylindrical roller bearings,relative to
its diameter, roller is fine and long. This is called needle
roller. Although it has a small section, the load bearing capacity
of bearing still had high, with thin and long needle bearing
roller, so the radial structure is compact, compered with the other
bearings,the size of the inner diameter and load capacity is the
same.and its has the minimum size of outside diameter, especially
for supporting structure of radial installation size restricted.
