    Abstract: The invention relates to a chain that consists of chain members with respective two inner flat links (1) that are parallel with respect to each other and two bushes (2) that are rigidly located between the inner flat links and that link two ends of said links each. The chain further comprises outer flat links (5) that interlink the chain members. Said outer flat links are parallel with respect to each other and hinge the ends of two adjacent chain members that face each other by rigidly linking each of the opposing ends with one respective end of the pin. Said opposing ends link two ends of two outer flat links which in turn link two chain members. Said pin is guided through a bush and is rotatably received therein. The bushes protrude at their two ends from the outer faces of the inner flat links that face the respective outer flat links and said protrusion is provided with at least one lubricant passage (6) that extends from the outer diameter to the inner diameter of the bush.
