Abstract
A bearing includes an inner bearing ring on which a raceway is formed. The ring includes at least a first component of light metal material and at least a second component of fully dense ceramic material, where the first component and the second component are separate entities joined together, and where the second component forms at least part of the raceway. The first component includes two lightweight metal parts interconnected by a screw thread which can be tightened to induce compressive pre-stress in the second component to compensate for low tensile strength of the ceramic material.
