Power Transmission Sprocket

This TRITAN sprocket is a plain bore steel component designed for 80 chain size and 12 teeth. It serves maintenance and repair operations that need a direct replacement for worn power transmission parts. The black oxide finish protects against corrosion in industrial environments.

Compatibility Check

Verify that your shaft diameter matches the 1 in bore and that the hub projection of 1.05 in clears adjacent components. Confirm the chain pitch is 1 in and the hub diameter of 3 1/8 in fits within your assembly. No keyway or set screws are included for locking.

Build Integration

The sprocket mounts directly on a plain shaft and transmits motion through a single strand of 80 chain. Its 4.33 in outside diameter and 3.864 in pitch diameter define the drive ratio. The steel construction handles standard loads without requiring additional hub hardware.

Questions about this item

Does the sprocket ship with a keyway, set screws, or any mounting hardware, or must those be sourced separately?

The sprocket has no keyway and no set screws, so it arrives as a plain-bore component only. Any key, set screws, or other mounting hardware must be purchased separately.

How do I decide between the 12-tooth version and another tooth count for my 80 chain drive?

Choose the 12-tooth model when the design calls for a 3.864 in pitch diameter and a 4.33 in outside diameter; a different tooth count changes both diameters and the speed ratio.

What does the 3.864 in pitch diameter mean once the sprocket is installed on a 1 in shaft driving an 80 chain?

It defines the effective radius where the chain engages, so each revolution advances the chain by 12 times the 1 in pitch, giving the speed and torque ratio for the drive.
