Martin Sprocket & Gear, Inc. Datasheets for ANSI Roller Chain Sprockets

Roller chain sprockets engage chain drives in power transmission and conveyor systems, though sprockets can engage any perforated material. Chain drives can be highly efficient and can produce a mechanical advantage as speed reducers/increasers. Sprockets conforming to ANSI standard B 29.1 are not meant to engage roller chains of any other parameter. ANSI conforming roller chain is smaller and somewhat weaker than its European counterpart.
