| Abstract: | To achieve precision in forming of bearing outer ring for high-speed rail, the finite element simulation of cold rolling process with varying parameters is conducted using ABAQUS finite element software. The influence of process parameters on end face shaping quality of bearing outer ring for high-speed rail is investigated. It is concluded that higher drive roller speed and core roll feed rate are conducive for the forming of high speed rail bearing billet, and smaller rolling ratio is beneficial to the forming quality of the upper end face of the billet. The study results provide reliable theoretical foundation for the actual production of bearing outer ring for high-speed rail
