Martin metric double strand solid construction sprockets have proper spacing between chain rows.

Martin does not stack “A” plates on multiples, but instead Martin machines teeth after the chain rows are already in place.
These plain bore sprockets can easily be bored to a metric or standard size to fit your application.
Keyways, set screws and harden teeth are quick alterations that can be made.
Tolerances meet or exceed ISO standards
Manufactured of high carbon steel
Precise machining and processes ensure consistent finish and high quality
Bores are concentric to pitch line, minimizing run out
Chain rows are parallel and precisely spaced to increase longevity of sprocket and chain
