Plain Styles

BlackStar plain bore sprockets are a cost-effective solution that can be machined on-site to meet specific application requirements.

Made from solid forged steel for strength and durability, BlackStar plain bore sprockets feature a simple design that can be customized to fit different shaft sizes and configurations. Choose A-style for a flat, hubless plate sprocket with a standard bore that can be machined out to accept weld-on hubs or other accessories. B-style sprockets come with a hub on one side of the plate while C-style sprockets have hubs on both sides. These hubs can be bored to size before keyways and setscrews are added for secure mounting.

For budget-friendly, on-site customizations, choose BlackStar plain bore sprockets.
