Tritan 80BS17H 17-Tooth Sprocket

The Tritan 80BS17H is a finished-bore roller chain sprocket machined from steel with a black oxide finish. It fits a 1 1/4 inch bore and includes a 1/4 inch keyway plus two set screws for secure shaft mounting. The sprocket carries 17 teeth for a number 80 chain with a one-inch pitch.

Suited Applications and Limits

This sprocket serves maintenance teams and OEMs replacing a worn number 80 chain drive on conveyors, agricultural equipment or industrial machinery where a fixed 1 1/4 inch bore matches the existing shaft. It does not suit drives requiring a different bore diameter, a larger tooth count or a multi-strand chain configuration.

Included Hardware Impact

The supplied keyway and pair of set screws eliminate the need to source separate locking hardware, reducing assembly time during installation. The black oxide coating adds a layer of corrosion resistance that helps protect the steel teeth in damp or outdoor environments.

Questions about this item

Does the 1 1/4 in bore with 1/4 in keyway match my existing shaft?

The sprocket has a fixed 1 1/4 in bore and a 1/4 in wide keyway; verify your shaft diameter and key dimensions match these before installation.

Will this 80 chain pitch sprocket mesh with my current 80 roller chain?

Yes, it is cut for 80 pitch chain with 17 teeth and a 5.442 in pitch diameter, so it will engage any standard single-strand 80 roller chain.

How can I confirm the sprocket is seated correctly after tightening the two set screws?

Check that the hub face is flush against the shaft shoulder, rotate by hand to feel smooth engagement with the chain, and ensure no radial wobble at the 5.95 in outside diameter.
