Finished-Bore Steel Sprocket

The Tritan 40BS15H is a new steel sprocket with a 7/8 in finished bore, keyway and set screws included. It carries 15 teeth for single-strand 40 chain and has a 2.65 in outside diameter.

Mounting and Clearance

The one-side hub measures 1 13/16 in across and projects .591 in from the sprocket face. Two set screws lock the bore to the shaft while the 3/32 in deep by 3/16 in wide keyway prevents rotation under load.

Fit for Maintenance, Not Custom Builds

Maintenance crews replacing a worn 40-chain sprocket on existing equipment will find the fixed bore and black-oxide finish ready to install. Builders designing a new drive who need a different tooth count, bore size or hub style should look elsewhere.

Questions about this item

At what pitch diameter does the sprocket reach its wear limit under continuous load?

The pitch diameter is 2.405 in, so chain stretch beyond this dimension signals the wear limit.

How much hub projection adds heat or drag during all-day operation?

Hub projection measures 0.591 in, keeping rotational mass low for minimal heat build-up.

What shaft size and keyway must already be on the machine for this sprocket to fit?

A 7/8 in shaft with a 3/16 in wide by 3/32 in deep keyway is required.
