Double Single Sprockets

Double single sprockets are designed to run two single-strand type roller chains, this is where the name "double single" came from. Typically these sprockets are A style but both BTB taper bushed and QD style is available from stock. Our double single sprockets are manufactured with hardened teeth and have a black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double single sprockets range from ANSI #40 - #160 but additional sizes can be manufactured upon request. We can also supply quick reaction custom re-bores and MTO specialty double single sprockets because of our quick reaction in-house machine shop. Something important to note is that even though these sprockets are double sprockets they will not double-strand roller chain. The charts below show the in-stock double single sprocket sizes and have clickable links to the product pages themselves.
