When your production line stops for a worn-out sprocket, time is money. You do not need a standard off-the-shelf part; you need a hubbed sprocket with custom boring that matches your exact shaft dimensions. Yet the biggest challenge for most engineers and procurement managers is the lead time. Traditional machining shops often require a week or more to cut a bore, broach a keyway, and install set screws. That is why we have revolutionized our workflow: we now machine bore, keyway, and set screws on hubbed sprockets within 24 hours.

Our dedicated manufacturing cell focuses exclusively on hubbed sprockets with custom boring. Every order, whether a single prototype or a small batch, is processed through CNC lathes and keyway broaching machines optimized for rapid changeover. We maintain a large inventory of raw hubbed sprockets in multiple pitch sizes, tooth counts, and hub diameters. This means we can start the custom machining immediately upon receiving your shaft specifications. The process is straightforward: you provide the desired bore diameter (down to 0.001” tolerance), keyway width and depth per your standard (metric or inch), and set screw location. Within one working day, we deliver a fully finished sprocket ready to install.

The engineering behind our rapid service relies on precision tooling and strict quality checks. After the bore is machined, we cut the keyway using a vertical broaching press that ensures perfect alignment with the sprocket’s centerline. Set screws are then installed at the correct angular position, often with dimpling or flatting on the hub to prevent shaft damage. Every completed hubbed sprocket with custom boring is inspected with a go/no-go gauge for bore diameter and keyway fit. This guarantee of accuracy eliminates the risk of rework or downtime when you mount the sprocket on your equipment.

For industries such as conveyor systems, agricultural machinery, packaging lines, and power transmission, the ability to get a custom machined sprocket in 24 hours is a game-changer. It allows maintenance teams to reduce spare part inventory while still being prepared for emergency breakdowns. It also helps OEM manufacturers who need small quantities of hubbed sprockets with custom boring for new product prototypes without waiting weeks for special production runs.
