Entity-type needle roller bearings
 
The basic structure of the inner ring bearing NU-type cylindrical roller bearings, but the introduction of the needle, the volume can be reduced, and can withstand large radial load bearings without inner ring should have appropriate precision and hardness of shaft mounting surface as raceway.
 
Thrust needle roller bearings
 
Separation of bearings by the the raceway ring with needle roller and cage assemblies, and any combination of thin stamping process raceway ring (W) or cut processing thick raceway ring (WS). Keep non-separable bearings are processed by precision stamping the raceway ring with needle roller and cage assemblies of the overall type bearing. Kind of bearings can withstand axial load. Small footprint, is conducive to compact mechanical design, mostly using only the needle roller and cage assemblies, and the mounting surface of the shaft and housing as a raceway.
