💡 What is a chain sprocket used for and how does bore size affect mounting?

A chain sprocket is used to transfer rotation to a chain drive in power transmission systems, and bore size affects mounting fit and stability. - Proper shaft fit reduces slip and wear - Bore size affects alignment with the shaft (3/4 in / 19.05 mm) - Keyway and set screws secure the drive - Teeth count must match the chain pitch (#40) for smooth operation
