Sprocket for 80 chain, 12 teeth

This TRITAN sprocket is a finished-bore power-transmission component with a 12-tooth profile for single-strand 80 chain. It suits maintenance teams and machinery builders who need a direct replacement or a display piece for industrial hardware collections. The steel body carries a black-oxide finish and a transparent colour note from the supplier data.

Fixed bore with keyway and set screws

The bore is fixed at 1 in and includes a 1/4 in wide by 1/8 in deep keyway plus two set screws for shaft locking. Hub projection measures 1.05 in and length through bore is 1 5/8 in, so the sprocket slides on and secures without additional machining. Misalignment or an undersized shaft are the typical issues that prevent a clean fit.

Check shaft size, keyway and chain match

Verify that your shaft diameter is exactly 1 in and that the keyway dimensions match the 1/4 in width and 1/8 in depth. Confirm the drive uses single-strand 80 chain with a 1 in pitch so the 3.864 in pitch diameter and 4.33 in outside diameter engage correctly. Buyers needing a different bore, tooth count or multi-strand capacity cannot use this sprocket.

Questions about this item

How can I confirm the 12-tooth sprocket is correctly installed and meshing with 80 chain?

After mounting on a 1 in bore shaft using the 1/4 in wide by 1/8 in deep keyway, tighten both set screws. Rotate by hand; the 3.864 in pitch diameter should engage the 1 in pitch chain smoothly without binding or excessive play.

What components are included with the sprocket and what must be sourced separately?

The sprocket comes with two set screws and a finished 1 in bore with keyway. You must supply the matching 80 chain, a 1 in diameter shaft, and any additional mounting hardware such as bearings or retaining collars.

Which bore and tooth-count version should I select for a 1 in shaft running 80 chain?

Choose the 12-tooth model with 1 in finished bore, keyway, and black oxide finish. It matches a 1 in shaft, 1 in chain pitch, and provides a 4.33 in outside diameter for standard 80 chain drives.
