28CTB45 (4040) METRIC - RIM ONLY
- 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.
- Taper bushed sprockets have a tapered bushing bolted into a taper bore with hex head set screws instead of bolts.
- 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
- Chain rows are parallel and precisely spaced to increase longevity of sprocket and chain
- Interchangeable with other manufacturers’ Taper bushings
