Needle roller and cage assemblies are separate components and are ready-to-mount bearings without inner and outer rings. In applications where the shaft and housing bore are used as raceways, this assembly can be used in bearing arrangements requiring minimal radial space. Since the clearance of the bearing arrangement is only affected by the type of rollers and the shaft and housing finish, very precise bearing arrangements can be achieved.
Detail
Needle roller bearings are assembled with many slender needle rollers whose length is 3 times to 10 times the diameter. The structure is compact. The diameter of the inscribed circle of the needle rollers is relatively close to the outer diameter of the bearing, so it has a large radial load capacity.
