Inner rings

Inner rings are a basic component of bearing assemblies and form the inner raceway for rolling elements. They provide guidance for the rolling elements and transmit loads within the bearing's construction.

The function of inner rings depends on the dimensional accuracy and geometric quality of the raceway and on the surface finish, which influence the behaviour of the rolling elements. Correct implementation of these parameters is a prerequisite for the reliable operation of the bearing assembly.

They are part of bearing accessories and constitute a separate inner raceway in bearing assemblies; their structural design is intended to work together with the other parts of the bearing.
