KOYO offers generation I, II & III hub units using balls or tapered rollers for automotive wheel bearings. Due to recent trend of increased customer requirements for energy efficiency and environmental considerations, a need for improved wheel bearing performance is needed to be more and more improved. KOYO has developed an advanced and reliable shaft clinching technology and has new hub units with this technology. In this paper, some keypoints about the new shaft clinching technology are explained. Furthermore, observation of the shaft deformation process and FEM analysis results are shown to explain the occurrence of axial force, which is caused by the axial stress balance caused from the elastic deformation between the shaft and the inner ring during the clinching process.
