Abstract
A chain link for a roller chain or a sleeve-type chain that has a plurality of link plates with openings for receiving chain sleeves that can be brought into engagement with a sprocket wheel to transmit force. The chain sleeve has a central region that is engaged with the sprocket wheel and that has a larger outer diameter than its end regions that are held in the link plate openings. A method is disclosed for producing a chain sleeve for a chain link of a chain, which is produced by deep drawing, or by machining.
