1. Process of cylindrical roller bearing blank forming → deburring or ring → soft grinding raceway surface → soft grinding double end face → thermal solution → pre rough grinding rolling surface → rough grinding double end face → post rough grinding rolling surface → final grinding double end face → fine, final grinding rolling surface → super finishing rolling surface → cleaning, boring → final inspection appearance, dimension grouping → oiling packaging. 2. Process of taper roller bearing blank forming → deburring or ring → soft grinding raceway surface → soft grinding double end face → thermal solution → rough grinding rolling surface → fine grinding rolling surface → grinding ball base surface → final grinding rolling surface → super finishing rolling surface → cleaning, boring → Final Inspection Appearance, Dimension Grouping → oiled packaging. If the convexity is less than 0.005 mm, some of the rollers can be directly processed in the super-finishing process, individual can be in the final grinding of rolling surface grinding process out crown, and then ultra-finishing.
