Jeremywell #25 Roller Chain Sprocket
Sprockets are durable toothed wheels that are used in combination with roller chains to power all types of machinery. As the sprocket spins, the teeth grab onto the chain and move other parts that interlock with the chain.
Using the right sprocket is just as important as choosing the right chain. If both pieces don’t complement each other, the system will not operate correctly. At Jeremywell, we offer a wide selection of high quality standard roller chain sprockets. Our sprockets are engineered to perform well under pressure and are long-lasting.
There are a broad selection of factors to keep in mind when selecting replacement sprockets, a simple way to determine the right sprocket is by considering the following factors:
- The type of chain you would need the sprocket for.
- The style of sprocket you are looking for:
- Type A (Flat sprocket, no hubs)
- Type B (1 Hub)
- Type C (2 Hubs)
- Number of Teeth needed.
- Sprocket bore size.

I had originally used the 14 tooth #25 sprocket (drive sprocket) that Jeremywell sells, on an eletric scooter project i was building with an 80 tooth #25 sprocket (driven sprocket) with the 10 ft #25 chain that they also sell and both sprocket and chain look in very good quality and feel very durable A++. I ended up switching to this 11 tooth #25 sprocket for higher torque. Since ive had both of them and also the chain for about 6 or so months, I haven't had any problems with either. I will definitely buy from this seller if i need any replacement in the future.

i recently ordered three sprockets from Jeremywell to replace the obsolete belt drive parts for my Craftsman belt/disc sander. altho i haven't had them on long enuf to see how they'll stand the test of time, they seem to be well made and i was very pleased that they were shipped to me promptly in three or four days.the Amazon ad did not show me the dimensional specs that i needed to know because i needed to re-bore one of the sprockets to fit one of the shafts, but i was happy to find the specs on Jeremywell's website. it would have been helpful to have the specs shown on Amazon's site, but i did find them.the only complaint i have is that tho the first two sprockets i received came with set screws, the third one did not. i happened to have two of the correct size set screws in my shop so it wasn't much of a problem, but anyone that didn't have them in stock would have been quite unhappy.

Sprockets are true and run straight, bore sizes are accurate and set screws are included. Good buy.

Clean casting that is nicely finished. Two set screws ensure good hold on 1/2 inch diameter rod.
