EM Clutch and Brake lineup

Miki Pulley offers a wide variety of clutches and brakes to the motion control industry worldwide.  With decades of experience, our designs have been tested and refined to deliver unparalleled quality and reliability.

As the name suggests, Electromagnetic Clutches and Brakes function by utilizing the magnetic force generated by the energized coil.  These products may be divided between two basic functions:  ‘energized’ and ‘de-energized’.   In the ‘energized’ type, the clutch or brake is operated when power is supplied to the coil.  In the ‘de-energized’ type, the energized coil exerts force on the moveable plate, thereby compressing a series of springs that were otherwise holding the movable plate against the rotor. Then when de-energized, the springs are free to push the plate against the rotor to stop rotation.

Miki Pulley provides quality industrial Clutches and Brakes to many well-known OEMs throughout the world.  Our Clutches and Brakes have proven their value in the industry, meeting and surpassing customer requirements in terms of quality and service life.

With a wide range of sizes available, you may also choose between shaft or flange mounted types. 

This product is primarily used in the following machine industries:


101 clutch CS
CSZ
101 model CS model CSZ model

101 model

101 model:
The 101 model is durable, versatile, and available with three different armatures. The 101 is a simple design, consisting of clutch stator, rotor, and armature assembly. You may choose between shaft or flange mounted types. The 101 is the same as the CS in operation and size range. The only difference is mounting style: the 101 is for shaft mounted applications.

  • Brake Torque: 3.687ft*lb ~ 236.02 ft*lb (5Nm ~ 320Nm)
  • Ambient Temperature: 14 F ~ 104 F; (-10 ℃ ~ 40 ℃)
  • Backlash : Zero

CS model

CS model:
The CS model is durable, versatile, and available with three different armatures. The CS is similar to the 101, consisting of clutch stator, rotor, and armature assembly. It has excellent torque transmission characteristics, with matched durability. The CS is the same as the 101 in operation and size range. The only difference is mounting style: the CS is for flange mounted applications.

  • Brake Torque: 3.687ft*lb ~ 236.02 ft*lb (5Nm ~ 320Nm)
  • Ambient Temperature: 14 F ~ 104 F; (-10 ℃ ~ 40 ℃)
  • Backlash : Zero

CSZ model

CSZ model:
Mounting the CSZ model is fast and easy, in that it is all part of one integrated structure designed around the CS-35 bearing. This drastically reduces time adjusting the gap, and fine-tuning concentricity and run-out.

  • Brake torque: 1.77 ft*lb ~ 7.376 ft*lb (2.4Nm ~ 10Nm)
  • Ambient Temperature: 14 F ~ 104 F; (-10 ℃ ~ 40 ℃)
  • Backlash : Zero
