Inner rings are made from hardened rolling bearing steel and have precision machined or ground raceways.
They are used where:
The shaft cannot be used as a raceway for needle roller and cage assemblies, drawn cup needle roller bearings with open ends or with closed ends and needle roller bearings;
Needle roller bearings must be combined with wider inner rings in order to allow larger axial displacements of the shaft in relation to the housing;
Optimum running surfaces are required for seal lips.
IR inner rings have a precision machined raceway. Chamfers on the end faces allow easy insertion into the bearing and prevent damage to the seal lips of the bearing. Inner rings are available with and without a lubrication hole.
