A metric taper bushed sprocket is a sprocket where a tapered bushing is bolted into the taper bore that is machined in the sprocket.
When installed this bushing is compressed onto the shaft providing a tight grip.

Tolerances meet or exceed ISO standards
Manufactured of high carbon steel
Precise machining and processes ensure consistent finish and high quality
Bores are concentric to pitch line, minimizing run out
