Abstract
A section of chain for conveying product along a material handling system includes a pin connecting a center link between two side links. The pin may have a sleeve portion around and at least partially along the shaft portion of the pin. The sleeve portion may engage a center link of the section of chain and may be movable relative to the shaft portion. The sleeve portion may comprise a polymeric material. The sleeve portion may be molded over an I-pin or the like, or may be slid or pressed onto a stud-ended pin or bolt or the like. The pin may include a generally spherical-shaped ball member or portion on the shaft portion to enhance flexibility of the section of chain. The pin may be dialable or selectably positioned at the side links to control and adjust the wear surface of the pin relative to the chain links.
