SEALED CHAIN LINK ASSEMBLY

摘要

A chain link assembly including a first link pivotally joined to a second li nk by a pin. The first link has a pair of first sidebars joined by a first barrel. Each first sidebar includes first and second ends joined by an inner surface and an outer surface. The first ends of each sidebar define coaxial first apertures coaxial with the first barrel, and the second ends define coaxial second apertures. A second link has a pair of second sidebars joined by a second barrel. Each second sidebar includes first and second end s joined by an inner surface and an outer surface. The second sidebar first ends define coaxial first apertures coaxial with the second barrel and the second apertures of the fir st link, and the second ends of the second sidebars define coaxial second apertures. A pin extends through the first apertures and first barrel of the second link and the seco nd apertures of the first link to pivotally join the first link to the second link. In one embodiment, at least one of the links is formed from a single piece. In another embodiment, the p in is rotationally fixed relative to one of the links.
