ANSI Triplex Roller Chain
ANSI triplex (triple strand) roller chain for heavy-duty applications. Higher capacity than duplex and single strand chains.
Product Description
ANSI triplex roller chain (triple strand) uses three parallel strands to deliver very high power transmission. It provides excellent durability and long service life, especially suitable for heavy machinery, continuous production lines, and harsh environments.
Available in multiple sizes and materials (e.g., Mn40 alloy steel, SUS304 stainless steel, engineering plastic) to meet different industry requirements.
