Sprocket for 40 Chain and 1-Inch Shaft

This TRITAN sprocket fits 40 chain pitch with a fixed 1-inch bore and keyway. It is intended for power-transmission builds that need a single-strand drive on a one-inch shaft.

Steel Construction with Black Oxide Finish

The steel body carries a black oxide coating for corrosion resistance. Two set screws lock the hub to the shaft, and the 0.591-inch hub projection keeps the assembly compact.

Fifteen Teeth on 2.405-Inch Pitch Diameter

The 15-tooth design yields a 2.405-inch pitch diameter and a 2.65-inch outside diameter. Buyers needing a different tooth count or bore size should select another sprocket.

Questions about this item

How do I install the 15-tooth 40 chain sprocket on a 1 in shaft and what step is often missed?

Slide the sprocket onto the 1 in shaft, align the 1/4 in wide by 1/8 in deep keyway with the shaft key, then tighten both included set screws against the key and shaft flat; the step often missed is securing the second set screw.

What maintenance or replacement will the 40BS15H sprocket need over time?

Inspect the 15 teeth for hooking or uneven wear from the 1/2 in pitch chain; replace the sprocket when tooth profiles become pointed or the 2.65 in outside diameter shows measurable reduction.

What is the first limit that appears when the steel sprocket runs continuously under load?

The 0.591 in hub projection and 7/8 in length through bore concentrate heat, so tooth-surface temperature rise from friction becomes the limiting factor before the black-oxide finish degrades.
