Hardened teeth sprockets afford longer chain and sprocket life
Tolerances meet or exceed ANSI standards
Manufactured of high carbon steel
Precise machining and processes ensure consistent finish and high quality
Chain rows are parallel and precisely spaced to increase longevity of sprocket and chain
Bores are concentric to pitch line, minimizing run out
Interchangeable with other manufacturers’ QD bushings
