#40 Chain Coupling Sprockets

Get a Quote

Coupling sprockets are manufactured to ANSI B29 standards but have a smaller outside diameter and use a special tooth profile as shown in the photo 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 durability reasons. We standardly stock plain-bore, finished bore, and bushed style coupling sprockets.
