Tritan 40BS09H 5/8 in Bore Sprocket

This new Tritan sprocket is a finished-bore power-transmission component for single-strand 40 chain. It fits a 5/8 in shaft with a 3/16 in wide by 3/32 in deep keyway and two set screws. The steel body has a black oxide finish and a transparent appearance. It is suited for maintenance, repair or light-duty drive assemblies.

Nine-tooth capacity with 1.462 in pitch diameter

The sprocket has 9 teeth, a 1.67 in outside diameter and a 1.462 in pitch diameter. Hub projection is .591 in and length through bore is 7/8 in. This pitch diameter and tooth count suit compact drives where space is limited. The fixed bore and single-strand design limit use to standard 1/2 in pitch chain in straight-line or simple offset layouts.

Replaces worn 40-chain sprockets with 5/8 in bore

It directly replaces a damaged or worn sprocket of the same chain size, bore, keyway and tooth count. The jump is worth it when the original shows tooth hooking, excessive noise or set-screw loosening. Buyers needing a different tooth count, double-strand capability or a larger bore will need a different part.

Questions about this item

Will the 5/8 in bore and 3/16 in keyway fit the shaft on my existing 40 chain drive?

The sprocket has a fixed 5/8 in bore with a 3/16 in wide by 3/32 in deep keyway, matching standard 40 chain shaft dimensions.

How can I confirm the 9 tooth sprocket is seated correctly after installation?

Verify the 1.67 in outside diameter clears surrounding parts and that the two set screws lock firmly onto the keyed shaft.

Does the box include the two set screws, or do I need to buy them separately?

The package includes the two set screws; no additional hardware is required for mounting.
