ABSTRACT:
A chain for use primarily in conveyor systems includes a plurality of male and female links pivotally coupled together. The female link includes a generally I-shaped body segment and a pair of bifurcated arms at each end. The arms are asymmetrically formed so that one arm defines a stop for preventing turning of the pivot pin and the other arm defines an enlarged boss. The provision of the flanges along the body segment and the boss at the ends function to increase the bearing surface at points of greatest wear to thereby increase the useful life of the links. The provision of the boss further obviates the need for spacers heretofore required in such chains of the prior art.
