Abstract
A conveyor chain with a universal coupling joint connecting consecutive chain links. The joint includes a joint member unitarily molded with a first link body engaged by a separately formed joint element insertable into a second adjacent link body to link the two link bodies at the joint. The insertable joint element may be made of a different material from the link body. The joint member has a convex or concave spherical bearing surface that engages a complementary concave or convex bearing surface on the joint element for universal pivoting.
