ANSI Duplex Roller Chain
ANSI duplex (double strand) roller chain for heavy-duty power transmission. Higher load capacity and stable operation.
Product Description
ANSI duplex roller chain (double strand) is manufactured to ANSI B29.1 with two parallel strands, providing higher load capacity and durability than single strand chain.
Commonly used in heavy industries such as cement, mining, steel, wood processing, agriculture, and precision machinery.
Available in multiple sizes and materials (e.g., Mn40 alloy steel, SUS304 stainless steel, engineering plastic) to match different industry requirements.
