Industrial Sprocket for 80 Chain

The Tritan 80BS11H is a finished-bore steel sprocket built for single-strand 80 pitch chain. It has 11 teeth, a 1 in bore with a 1/4 in keyway and two set screws, and a black oxide finish for corrosion resistance.

Suited for Fixed-Shaft Drives

This sprocket fits shafts that accept a 1 in bore with a 1/8 in deep keyway. Builders needing a different bore size, more teeth, or a split-hub design will need a different component.

Mounts Directly on Keyed Shafts

The 2 13/16 in hub projects 1.05 in through the bore, locking onto the keyway and set screws. The 4.01 in outside diameter clears standard guards while the 3.55 in pitch diameter matches 80 chain geometry.

Questions about this item

What chain size and tooth count must my existing roller chain have to mesh with the 80BS11H sprocket?

The sprocket is cut for 80 chain pitch and has 11 teeth, so the chain must be ANSI 80 single-strand roller chain.

Will the 1-inch finished bore with 1/4-inch keyway and two set screws fit the 1-inch shaft I am keeping from the old drive?

Yes, the bore is 1 inch with a 1/4-inch wide by 1/8-inch deep keyway plus two set screws for locking to a 1-inch shaft.

After installation, how can I confirm the sprocket is seated correctly on the shaft?

Verify the hub face is flush against the shaft shoulder, the key seats fully in the 1/4-inch keyway, both set screws are tight, and the 4.01-inch outside diameter runs true with no wobble.
