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 be dialable or selectably positioned at the side links to control and adjust the wear surface of the pin relative to the chain links. The pin may have a rotationally non-symmetrical shaft portion to provide different wear surfaces that engage a center link of the section of chain. The different wear surfaces may be sized and shaped to accommodate wear at the wear surface of the center link. The shaft portion may include a rotationally non-symmetrical ball member or portion on the shaft portion to enhance flexibility of the section of chain. The pin may be dialed to the next position or wear surface in response to an output of a wear measurement device or system.
