Vallast Roller Chain Half Link, #80H

Vallast Roller Chain Half Link, #80H

The Vallast OL80HE #80H Roller Chain Half Link (Offset Link) is a heavy-duty offset link designed for ANSI #80H roller chain systems, allowing users to adjust chain length by a single pitch when a standard connecting link will not provide the correct fit. Built from durable carbon steel, this heavy-series (#80H) offset link is designed for demanding power transmission applications in agricultural, industrial, and mechanical equipment. Featuring a solid bushing and solid roller design, it delivers reliable strength and wear resistance while maintaining smooth chain operation—because sometimes the difference between perfect chain tension and frustration is exactly one link.
