inner rings are made from hardened rolling bearing steel and have precision ground or machined raceways. ideal applications for using inner rings include when in order to allow larger axial displacements of the shaft in relation to the housing, needle roller bearings must be combined with wider inner rings.

needle roller bearings are used with radial loads only, and their selection is typically based on the amount of the load, whether an inner ring is required, the material that the rollers, rings, and cage are made from, rotational speed, operating temperature, internal clearance for thermal expansion, and whether the bearing has seals or shields

needle roller and cage assemblies are single or double row units comprising cages and needle rollers. as their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope.
nadella needle roller bearing rna2095 1. instruction of needle roller bearings: needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. in spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
