Flanged inner ring for orbital forming operation

A flanged inner ring, comprising:

• a rolling edge configured to axially preloaded a radially inner ring of a rolling bearing after being plastically deformed,
• wherein, the rolling edge includes a diameter of increasing variable size along an axis (X) of symmetry of the flanged inner ring and, wherein the increasing variable size increases along the axis (X) in a direction away from the radially inner ring,
• wherein
• the rolling edge includes an outer preloading surface configured such that in a deformed configuration the outer preloading surface is arranged against the radially inner ring and such that in an undeformed configuration the outer preloading surface is inclined away from the axis (X) of symmetry of the flanged inner ring;
• wherein the rolling edge further includes an inner cylindrical surface coaxial with the axis (X) of symmetry.
