ANSI CHAIN COUPLING SPROCKETS

Coupling sprockets are created to ANSI B29 standards but have a smaller outside diameter and use a special tooth profile as displayed in the photography below.

This tooth profile allows for the sprockets to seat the chain properly and run inside a coupling cover. It is always recommended to use an aluminum coupling chain cover when running roller chain couplings for safety, performance, and strength reasons. We standardly stock plain-bore, finished bore, and bushed style coupling sprockets. If you don’t see the specific sprocket needed please contact us and we can custom manufacture it.
