Tritan 80BS11H Sprocket for 80 Chain

The Tritan 80BS11H is a finished-bore steel sprocket built for single-strand 80 chain. It features an 11-tooth profile with a 4.01 in outside diameter and a 3.55 in pitch diameter. The hub measures 2 13/16 in diameter with a 1.05 in projection and a 1 5/8 in length through bore. A 1/4 in keyway and two set screws lock the 1 1/4 in bore securely.

Suits single-strand 80 chain drives on 1 1/4

This sprocket fits power-transmission systems using ANSI 80 roller chain on a fixed 1 1/4 in shaft. The black-oxide finish and included set screws simplify installation on keyed shafts. Builders needing a different tooth count, a larger maximum bore, a multi-strand hub, or a taper-lock bushing style should look elsewhere.

11 teeth on 80 chain pitch

The 11-tooth count on 1 in pitch chain fixes the pitch diameter at 3.55 in and the outside diameter at 4.01 in. This tooth count determines the speed ratio and chain wrap for the drive. If the application requires a different ratio or chain engagement, a sprocket with another tooth count is necessary.

Questions about this item

Does the sprocket arrive with set screws included, or must I purchase them separately?

Two set screws are included in the box, so no separate purchase is needed for installation.

How do I decide between the 11-tooth version and other tooth counts for 80 chain?

The 11-tooth model gives a 3.55 in pitch diameter and 4.01 in outside diameter; choose a different tooth count only if your speed ratio or clearance requirements demand it.

What do the 3.55 in pitch diameter and 4.01 in outside diameter mean once the sprocket is mounted on a 1 1/4 in shaft?

They define the chain wrap circle and the overall envelope, so verify that your guard spacing and centre distance match those dimensions before fitting.
