Jeremywell #40 Roller Chain Idler Sprocket 1/2" Bore Hardened 17 Tooth

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:
  • Idler Sprocket
  • Type A (Flat sprocket, no hubs)
  • Type B (1 Hub)
  • Type C (2 Hubs)
• Number of Teeth needed.
• Sprocket bore size.
