Concentric 25BS24 Roller Chain Sprocket 24 Tooth 1/2" Bore #25 Pitch 1-2742-24-D

If you're fixing or building something with a #25 roller chain, this sprocket is what you need.

It's a Concentric brand, model 25BS24.

That means it's got 24 teeth, a 1/2-inch bore, and it's made for #25 pitch chain.

It's a stock replacement part, brand new, still in the packaging.

The interchange number 1-2742-24-D should help you cross-reference it if you're swapping out an old one.

No UPC, but it's a solid industrial part.

Made to get things moving again.

Whether it's for a small conveyor, a go-kart, or some shop equipment, this little guy will do the job.
