Needle roller and cage assemblies are self-contained, ready-to-install bearings without inner and outer rings. In applications where the shaft and housing bore can be used as raceways, this assembly can be used to create bearing arrangements that require minimal radial space. Since the clearance of the bearing arrangement is only affected by the roller classification and the finish of the shaft and housing, very precise bearing arrangements can be achieved.

This series of bearings has high radial load capacity, high rigidity and high precision.
