Needle roller and cage assemblies
The needle roller and cage assemblies are components of bearings but can also be used as stand-alone bearings, for applications where a very small cross section is required. They can carry high radial loads at high operating speeds. No axial guidance required. Although cheap, the solution as a whole is expensive because the adjacent surfaces on the shaft and the housing have to be grinded and hardened.
