40-2 roller chain is a duplex roller chain with a 1/2" pitch. This chain is manufactured to ANSI B29.1 standards and directly interchanges with other manufactures. Our 40-2 chain is manufactured using heat-treated components for added strength, that are also shot peened for fatigue resistance, then the chain is pre-stretched at the factory so there is reduced long term elongation. We supply this chain as 10' boxes but also stock 50' and 100' reels for customers who need longer lengths of chain.
