IR40X45X20.5 Inner Rings are made from hardened bearing steel and have precision machined or ground raceways.
 
Applications:
1. 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.
 
2. Where the shaft cannot be used as a raceway (such as for drawn cup needle roller bearings with open ends; drawn cup needle roller bearings with closed end; needle roller and cage assemblies; and needle roller bearings).
 
3. When optimal running surfaces are necessary in order to seal lips.
