Sprocket for 35 Chain with 5/8 in Bore

The Tritan 35BS12H is a finished-bore sprocket built for single-strand 35 chain. It has 12 teeth, a pitch diameter of 1.449 in and an outside diameter of 1.63 in. A 5/8 in bore with a 3/16 in by 3/32 in keyway and two set screws locks it to the shaft.

Suits single-strand 35 chain drives needing

This sprocket fits shafts that accept a 5/8 in bore with the listed keyway dimensions. It will not work for multi-strand chain, for larger chain pitches or for shafts that require a different bore size or no keyway.

Handles 35 chain at the stated pitch diameter

The 1.449 in pitch diameter and 1.63 in outside diameter suit standard 35 chain loads. The 0.582 in hub projection and 1 1/4 in hub diameter limit how far the sprocket sits on the shaft, so very long hubs or wider chain cannot be accommodated.

Questions about this item

What shaft diameter does the 5/8 in bore sprocket fit?

The sprocket fits a 5/8 in shaft and includes a 3/16 in wide by 3/32 in deep keyway plus two set screws for secure mounting.

Will the 12-tooth 35 chain sprocket mesh with my existing 35 roller chain?

Yes, it is cut for 3/8 in pitch 35 chain with a 1.449 in pitch diameter, so it meshes directly with standard 35 roller chain.

How can I confirm the sprocket is seated correctly after installation?

Verify the hub face is flush against the shaft shoulder, both set screws are tight on the key, and the chain runs true on the 1.63 in outside diameter teeth.
