MARTIN SPROCKET & GEAR - MARTIN SPROCKET & GEAR 50JA12H

Martin saber tooth sprockets have hardened teeth, which provide longer chain and sprocket life.

The hardened teeth on the smaller sprocket of a roller chain drive are recommended if the drive ratio is four to one or greater if the smaller sprocket has 24 teeth or less and is running at a speed of over 600 RPM.

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

Stocked Heat Treat
