Pilot bore sprockets are high-precision sprockets designed for use in roller chain drive systems. Featuring a central pilot bore, these sprockets ensure accurate shaft mounting, concentricity, and reliable power transmission. They are ideal for industrial machinery, conveyors, and automated systems where precision and durability are critical.
ACORN® stocks a wide range of pilot bore sprockets, ready to buy online with fast UK and international delivery.
The Pilot Bore Sprocket, also called a Rough Stock Bore Sprocket, is secured onto the shaft using a bushing or a hub. The Sprocket is supplied with a bore that must be re-bored to fit the customer’s shaft size.
The sprocket has metal teeth which mesh with the links of a chain to transmit power and prevent slippage.
Pilot bore sprockets are commonly found in all areas of industrial machinery, as well as on vehicles which use drive chains, such as bikes or motorcycles.
