Needle roller bearings

Needle roller bearings are separable radial bea rings. The use of needle rollers allow for low sec tional heights in combination with high rigidity and excellent load carrying capability. If needle roller bearings work in confined space (e.g. gear boxes), they may also be used without inner rings, designation(RNA). In these cases the needle rollers run directly on the shafts. The running surfaces, however, must be hardened and ground to the same quality standard as for bearing raceways. Since needle roller bearings are optimum as non locating bearings as they allow for length cor pensation within the bearing. For applications where the non-locating bearings require bigger axial displacement, needle roller outer and cage assemblies can be combined with extra wide inner rings.
