Industrial Chain Sprocket

This new Tritan sprocket is a finished-bore power-transmission component built for single-strand 80 chain. Its 18-tooth steel body with a 2 inch fixed bore and integrated keyway suits maintenance teams and OEM assemblers who need a ready-to-mount drive element. Buyers requiring a different bore size, a multi-strand hub or a non-standard chain pitch cannot use this unit.

Thermals Noise Power

The steel construction with black-oxide finish dissipates heat through direct conduction to the shaft and hub, so no active cooling is involved. Operation is silent apart from normal chain engagement noise, and the component draws no electrical power itself. There are no fans, pumps or electronic controls to generate additional sound or heat.

Included Hardware

Two set screws are supplied to lock the sprocket onto the keyed shaft, and the 1/2 inch wide by 1/4 inch deep keyway is machined to standard dimensions. No lubricant, tensioning tools, alignment gauges or mounting instructions are bundled, so installers must provide those separately.

Questions about this item

How do I install the 18-tooth 80 sprocket on a 2-inch shaft and which step is often missed?

Slide the sprocket onto the 2-inch bore, align the 1/2-inch wide by 1/4-inch deep keyway with the shaft key, then tighten both included set screws against the key and shaft flat — skipping the second set screw is the common error.

What maintenance or replacement will this 80-chain sprocket need over time?

Inspect the 18 teeth for hooking or uneven wear; replace the sprocket when tooth profiles no longer match the 1-inch pitch chain, and re-torque the two set screws after the first hours of operation.

What limit appears first when this steel sprocket runs continuously under load?

The 0.925-inch hub projection and 1.5-inch length through bore concentrate bending stress on the keyway; sustained torque will fatigue the keyway corners before the 6.27-inch outside diameter or 5.759-inch pitch diameter surfaces wear out.
