Twelve Strand Roller Chain

Twelve-strand roller chain (octuplet) is manufactured for heavy-duty equipment such as drills, oilfield, large drives, and extreme duty conveyors. For your drive application, our chain is made using premium quality metallurgy components and high-performing features. This chain features side-plates that have been heat-treated and shot-peened, along with heat-treated pins and solid roller design. Most sizes also come standard with a non-split solid bushing for an even greater performance factor. We supply these chains in both riveted and cottered construction. We also supply twelve-strand roller chain sprockets and tensioners, contact our customer service team for pricing and availability.
