Electromagnetic Tooth Clutches
Tooth clutches drive through interlocking teeth instead of friction, giving the highest torque for their size of any electromagnetic clutch. They suit printing stations that must stay in time, low-speed engagement, gearboxes and machine tools.

How it works
How It Works
Teeth, Not Friction
Power to the coil pulls the toothed armature into mesh with the rotor, locking input and output together with no slip. Switch off and springs pull the teeth apart, so there’s no contact and no drag.
Why a tooth clutch
Positive Drive
Highest Torque per Size
More torque in a smaller package than any other electromagnetic style.
Single Position
MZS option engages in only one position for precise registration.
Zero Backlash
Optional tooth profile with no backlash.
Can Act as a Brake
Fix the output to a stationary part and it becomes a brake.
How to choose
Before You Choose a Tooth Clutch
Engage Slowly
Tooth clutches engage at low speed or standstill – they can’t slip to pick up a load.
Timing
Choose single-position if the stations must re-engage in the same place.
