Industrial Power Transmission Component

This Tritan roller chain sprocket is a finished-bore steel component designed for single-strand 80 pitch chain drives. It features 30 teeth with a 10.11in outside diameter and 9.567in pitch diameter for precise power transmission. The 2in bore includes a 1/2in keyway and two set screws for secure shaft mounting.

Maintenance Teams and OEM Assemblies

Maintenance crews replacing worn sprockets on existing 80 pitch drives will appreciate the ready-to-mount 1.425in hub projection and black oxide finish. Builders needing a different tooth count, bore size, or multi-strand configuration should look at alternative sprockets that match their specific drive requirements.

Included Fasteners Simplify Installation

Two set screws are supplied with the sprocket, eliminating the need to source separate locking hardware for the keyed connection. The fixed bore and one-sided hub design mean no additional bushings or adapters are required for standard shaft mounting.

Questions about this item

Does the 1.425 in hub projection on this 30-tooth sprocket require a specific shaft length to clear the hub?

The hub projects 1.425 in from the sprocket face, so the shaft must extend at least that far past the mounting surface to fully engage the 2 in bore.

Will the 1 in pitch of this chain number 80 sprocket mesh with an older 80-series roller chain I already have?

Yes — chain number 80 defines a 1 in pitch, so any standard single-strand 80 chain will engage the 30 teeth correctly.

After bolting the sprocket onto a 2 in shaft, how can I confirm the 9.567 in pitch diameter is running true?

Rotate the assembly by hand and check for radial run-out at the 10.11 in outside diameter; minimal wobble indicates the pitch circle is concentric with the shaft.
