ABSTRACT:
A chain link assembly is fabricated from a plurality of links joined together in articulated relationship with each of the links having a first end with a complementary pitch opening and a second end with a complementary opening. A barrel having an inside diameter surface greater than the cross-sectional diameter of the complementary pitch opening and having milled end segments which extend through the shell of the barrel to provide flat surfaces which permit the milled end segments of the barrel to be press fit into the complementary pitch opening. A pin member having a cross-sectional diameter substantially less than the inside barrel diameter is positioned through the complementary opening in the second end of the links to complete the chain link assembly. The completed chain link assembly provides a one-piece outer circumferential bearing surface on the barrel throughout the entire angle of articulation.
