Imported Double Roller Chain, #50-2

50-2 roller chain is a duplex roller chain with a 0.625" pitch. This chain is manufactured to ANSI B29.1 standards and directly interchanges with other manufactures. Our 50-2 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.
