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 taper bushed and QD style is available produced as custoemrs’ request. Our double single sprockets are manufactured with hardened teeth and have a original colour or black oxide coating for superior performance and a slight corrosion resistance. Stock sizes of double single sprockets range from ANSI #40 – #80/DIN06B-16B but additional sizes can be manufactured upon request. Something important to note is that even though these sprockets are double sprockets they will not double-strand roller chain.
