The inner rings of needle roller bearings are available as separate components. They are often used in combination with needle roller and cage assemblies or drawn cup needle roller bearings for applications where the shaft cannot be hardened and ground. IR series inner rings are standard inner rings used in needle roller bearings.
This series of bearings can not only achieve complete interchangeability of the inner ring, but also can be used for the standard inner ring of needle roller bearings, and can accommodate axial displacement in both directions.
