8mm Pitch Pilot Bore Sprockets – Precision Roller Chain Sprockets

Find the best 8mm sprockets on the market built to drive your chain with precision and reliability. At Bolton Engineering Products Ltd (BEP Ltd), we provide precision ground roller chain sprockets with pilot (rough stock) bores so you have the freedom and flexibility to machine both your own A/Fs and shaft diameters.

Our 8mm pitch sprockets offer an unrivalled range for applications where standard finished bore sprockets do not suit to meet the demands of engineers and maintenance staff who need a drive solution that is versatile and cost effective.

What Is an 8mm Pilot Bore Sprocket?

An 8mm pitch sprocket with a pilot bore (also known as a rough stock bore sprocket) is supplied with an oversized, unfinished bore. This allows the sprocket to be machined to the exact shaft diameter required, including keyways or set-screw features.

Key Characteristics

• Designed for 8mm pitch roller chain
• Supplied with oversized bore for custom machining
• Precision-cut teeth for smooth chain engagement
• Secure, slip-free torque transmission
• Suitable for hubs or bushing installations

Why Choose 8mm Pitch Roller Chain Sprockets?

8mm pitch sprockets are commonly used in compact and medium-duty chain drive systems, especially where metric standards are required.

Key Benefits

• Accurate tooth geometry ensures smooth chain operation
• Strong, durable construction for long service life
• Allows complete control over bore size and mounting
• Ideal for retrofit, replacement, or custom machinery
• Suitable for continuous and intermittent operation
• Cost-effective alternative to finished bore sprockets
