Study on the impact of roller convexity excursion of high-speed cylindrical roller bearing on roller…

1/9/2016· For high-speed cylindrical roller bearing, roller crowning of cylindrical roller bearing is usually utilized to alleviate stress concentration at both ends of roller. Nevertheless, due to machining factors of roller''s crowned profile, the crowned shape of roller may somewhat deviate from the roller mid-length point, known as roller convexity excursion.
