Toothed-Jaw Clutch

Polyclutch® jaw-type clutches permit extremely simple, reliable phase adjustment, and/or engage-release between a shaft and gear, pulley, roller, etc. The D Series is knob operated, the J Series is lever operated. Clutch teeth are precision machined from solid steel blanks, 3º tooth spacing (120 teeth) is standard. Alternate spacing is available. Jaw clutches are stronger than the shaft driving it.
