Abstract

A chain link for an energy guide chain. The chain link has two link plates, and at least one pivotal transverse web, which connects the link plates together in an articulated manner and which can be converted into a closed position that connects the link plates together and into an open position that at least partly releases the link plate intermediate space. At least one pivotally designed end region of the transverse web can be secured to the link plate in a latching manner. The articulated connection between the transverse web and the link plate has a substantially cylindrical joint pin with a radius (R1) over at least one part of the circumference of the pin on one of the corresponding components consisting of the transverse web and the chain link and a substantially cylindrical pin receiving area on the other of the two corresponding components.
