Inch and Metric. 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.

Inner Rings for Shell Type Needle Roller Bearings Inner Rings for General Usage IKO Inner Rings are heat-treated and finished by grinding to a high degree of accuracy. In the case of needle roller bearings, normally, the shafts are heat-treated and finished by grinding, and used as the raceway surfaces.
