Abstract
A plate chain comprising outer and inner chain links which are interconnected at joint places formed as slide bearings, with each joint place formed by a sleeve of the inner chain link and by a pin bolt of the outer chain link which rotates in the sleeve substantially about its own axis. The wear characteristics of the resulting joint places are improved. At least one portion of the lateral surface of the pin bolt and an associated portion of the inner surface of the sleeve have a different circumferential contour at the pulling side, so that the pin bolt is supported on the sleeve at least two circumferentially spaced-apart points or lines of contact at the pulling side. A method for producing chain members includes forming a sleeve with a joint trough.
