A hybrid type chain having a low wear pivot joint between inner and outer links has been provided. Both the inner and outer links of the chain are pin links with the pins tightly received, respectively, in the sidebars of the links. Each pin of an inner link is engaged with the adjacent pin of the adjacent outer link in linking engagement to form a pivot joint. All pins have convex, arcuate faces for rocking engagement between the pins at the pivot joint between links.
