20B-3 roller chain is a 31.75mm pitch triplex (triple-strand) metric roller chain made per ISO and British Standards. As a triple-strand roller chain, it is engineered to operate in demanding applications that other strand widths would be incapable of. What makes our 20B-3 roller chain special is the use of high-grade alloy and carbon steel materials per component and processes like heat-treating and shot peening done to each component before assembly. The chain is also factory pre-loaded to reduce significantly or eliminate initial and long-term elongation. Stacking up these features produces an 20B-3 chain that is more capable and has a superior lifespan than others available. This chain is supplied as a 10ft box, including one connecting link. We also provide 20B-3 roller chain sprockets and tools for making replacement or repairs easier.
