Permanent Magnet Clutches and Brakes


Permanent Magnet Clutches and Brakes

Precision Tork units provide constant torque independent of slip speed. They offer excellent overload and jam protection for all drive train components and also provide soft starts with zero slip when a preset torque is reached. Precision Tork permanent magnetic clutches and brakes do not require maintenance and provide extremely long life.

Features and Benefits

  • Accurate Torque Settings – independent of speed
  • Large knurled torque adjustment ring makes setting and adjusting torque that much easier!
  • Infinite adjustability between minimum and maximum settings. This allows units to be fine tuned to your unique requirement.
  • Easy to read graduations.
  • Torque is extremely consistent and smooth at low, as well at high speeds.
  • #1 Choice for slow speed applications

Dependable performance

  • Smallest possible transition from static to dynamic torque. Virtually eliminates the “stick-slip” phenomenon associated with friction devices.
  • Long life. The only wearing parts are the ball bearings.
  • Extremely accurate. Precision Tork units out-perform all other devices at low RPM.

Versatile mounting: Easy to retrofit

  • Precision Tork units are available with hollow bores for mounting on motor shafts or jack shafts.
