Abstract

A joint for a dredging chain, in which two bearings are arranged in extensive co-relation, and in which each bearing comprises a corresponding outer bushing arranged in a retaining bead, while at either side of the retaining bead a link element is mounted on the pivot pin, characterized in that an internal bearing bushing having an external convex surface on the pivot pin is mounted, the outer bearing bushing provided on the retaining bead being provided. Of a corresponding internal concave support surface. (Machine-translation by Google Translate, not legally binding)
