FAQ

What is a ‘pilot bore’ on a sprocket?
A pilot bore is a small, unmachined hole in the center of the sprocket. It is intended to be machined by the end-user to the exact diameter required for their specific shaft, and often a keyway is also cut. This allows a single sprocket model to be adapted for various applications.

How do I confirm if this 12B sprocket is compatible with my chain?
You must verify that your chain is a 12B standard chain (ISO 606 / BS 228). A 12B chain has a pitch of 19.05 mm (3/4 inch). Mismatching the sprocket and chain size will lead to rapid wear and system failure.

What does the ‘B3’ in the model number signify?
The ’12B’ indicates the chain standard and ‘Z15’ specifies 15 teeth. The ‘B3’ is likely a manufacturer-specific code indicating hub style, material grade, or a specific production batch. For interchangeability, the primary parameters are the 12B chain size and the 15-tooth count.
