Tritan 120A15H 15-Tooth Sprocket for 120 Chain

This new Tritan sprocket is a steel power-transmission component built for 120 roller chain. It features 15 teeth, a 1 1/4 in plain bore and a 15/16 in length through bore. The black-oxide finish protects the 7.96 in outside diameter and 7.215 in pitch diameter surfaces. It suits maintenance teams replacing a worn drive sprocket on industrial machinery.

Buyers needing a keyway or set-screw fixation

This sprocket has no hub, keyway or set screws, so it cannot be locked to a shaft with those methods. Shops that require a hubbed design, a different bore size or a different tooth count must select another part. Collectors seeking pristine packaging should verify the manufacturer-direct shipping condition.

15-teeth 120-chain sprocket with 1 1/4 in plain bore

The 15-tooth profile and 120 chain pitch define the speed ratio and load capacity. A 1 1/4 in plain bore fits the shaft directly without a keyway. The 7.96 in outside diameter and 7.215 in pitch diameter confirm the gear geometry for the drive layout.

Questions about this item

Will this 120 chain sprocket with a 1 1/4 in plain bore fit the existing shaft on my older machine?

The sprocket has a 1 1/4 in plain bore with a maximum bore capacity of 3 1/4 in and a 15/16 in length through bore, so it will slide onto a matching shaft and can be secured with a key or set screw of your choice.

How can I confirm the 15-tooth sprocket is correctly meshed with my 120 chain after installation?

Check that the chain rollers seat evenly in each of the 15 tooth gaps, the pitch diameter of 7.215 in aligns with the chain pitch of 1 1/2 in, and the sprocket runs true without lateral wobble on the shaft.

Does the black-oxide finished steel sprocket come with a keyway, set screws or a hub, or must I supply them?

The unit is supplied as a plain-bore sprocket with no hub, no keyway and zero set screws; you will need to machine a keyway or drill for set screws yourself if your application requires them.
