Electric Jaw Clutches / Tooth Clutches (JEB)

Tooth Clutches & Electric Jaw Clutch

Jaw Clutches are designed to optimize size and space in your application. They are ideally suited for positioning, holding and indexing as well as situations that require the unit to maintaining positive registration between input and output shaft.

With pins available for single-position engagement, an electric jaw clutch is often used in applications that require exact positioning, including printing and labeling.

As with all standard CJM electric clutches, our jaw clutch products may be modified for special uses, and we can custom design a solution for your application. Our experienced engineers are ready for your toughest challenges.

Features of Tooth Clutches & Electric Jaw Clutch Units

Electric Jaw Clutches are available with either 24 or 100 volt DC coils as standard equipment, though other voltages are available to meet your needs. Carlyle Johnson stocks coils with voltages ranging 6 to 240 volts DC.

CJM jaw clutch products feature bi-directional operation, meaning operation is not dependent on rotation. Pins are also available with these designs to permit single position engagement.
