2021-6-29 · In a conveyor belt''s return position, rubber rolls shed sticky material to help prevent belt tracking issues. Secondly, rubber also generates more friction between the roll and the belt to grip the belt more effectively for better belt tracking. Lastly, rubber will not break down as quickly as steel in corrosive environments.
