Sprocket for 40 Chain Systems

The Tritan 40BS24H is a finished-bore sprocket built for single-strand 40 chain with a 1/2 in pitch. It suits maintenance teams and machinery builders who need a direct replacement with a 7/8 in bore, keyway and set screws included.

Steel Construction with Black Oxide Finish

The steel body carries a black oxide coating for corrosion resistance in normal industrial environments. A 3.831 in pitch diameter and 4.1 in outside diameter keep engagement consistent. Two set screws and a 3/32 in deep keyway lock the 7/8 in bore securely to the shaft.

Ready-to-Install Hardware Included

The hub measures 3 3/4 in diameter with a 0.716 in projection and 1 in length through bore. Two set screws and the machined keyway ship fitted, so the sprocket mounts without extra machining or separate fastener kits.

Questions about this item

How do I install the 7/8 in bore sprocket onto the shaft, and what step is often missed?

Slide the sprocket onto the shaft aligning the 3/16 in wide by 3/32 in deep keyway with the shaft key, then tighten both included set screws against the key and shaft flat to prevent rotation.

What maintenance or replacement will the steel sprocket with black oxide finish need over time?

Inspect the 24 teeth for hooking or uneven wear every few months; replace the sprocket when tooth profiles become pointed or chain rollers no longer seat cleanly in the 1/2 in pitch.

What is the first limit that appears when the 40 chain size sprocket runs continuously under load?

The 3.831 in pitch diameter and 1 in length through bore concentrate tooth contact forces; sustained high torque will accelerate tooth-face wear before the hub or bore shows distress.
