Heavy-duty electromagnetic magnetic particle clutches and brakes

For heavy-duty tension and torque control, a large series PB/PC is available. Like the smaller magnetic particle series, these units can be sized for consistent slip. These larger units come equipped with inlets and outlets for forced air cooling. They offer extremely long life with resistant wear particles and are suited for high cycle applications. The P series ranges in torque from 8.8 to 144 lb-ft or 12-195 Nm.

Benefits of Ogura magnetic particle clutches and brakes:

  • Torque is electrically controlled over a very wide speed range
  • Units are sealed and do not produce wear particles
  • Larger units are available with fans for forced air cooling, providing additional heat dissipation
  • Extremely fast torque response
  • Units can be sized for continuous slip
