Improved roller chain, characterized in that a single cylindrical connection element of the internal flanges, synthesized and self-lubricating, is disposed, which receives internally through an axial hole to the articulation axis of the outer flanges and which has a intermediate zone of greater length and larger diameter than the ends, of smaller diameter and suitable to receive the inner flanges of the joint, which stop against the steps determined by said areas of smaller diameter, which have extreme protruding areas with respect to the inner flanges of the chain, determining self-lubricated friction zones for the outer flanges.
