Abstract:
PURPOSE: To prolong the life and to lessen a danger of cracking even when a local load is large by an armoring which is simple in terms of a manufacturing technique, is hardly wearable and has withdrawability.
CONSTITUTION: The wear resistant surface armoring for rollers has many moldings which are mounted apart certain intervals with each other on the roller surface and project outward.
