- 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
