Abstract：The high-end bearings, such as the main bearings of high-speed machine tools and aero-engine bearings, are often in service under extremely severe working conditions and have a very high demand for high service life and reliability, which require a very good mechanical performance guarantee in the bearing area of bearing rings. As an advanced technology of bearing rings, the near-net cold ring rolling (CRR) method not only has remarkable technical and economic effects such as energy saving, material saving and high efficiency, but also can greatly improve the performance of bearing ring through cold plastic deformation strengthening, which has become the international mainstream forming technology of bearing rings. The research progress of the microstructure evolution during the CRR process, the influence of CRR on the subsequent heat treatment and the coordinated control of the CRR process and heat treatment transformation are briefly described, and the technical difficulties of the near-net CRR process for bearing rings are summarized and prospected.
