 Disc Magnetic Couplings

How Disc Couplings Work
Disc type couplings consist of two opposing discs with powerful rare earth magnets. The torque applied to one disc is transferred through an air gap to the other disc. Because of its simple flat design, you can have angular misalignment of up to 3º or parallel misalignment up to ¼” and still transmit nearly full rotational torque. You could also fabricate an inexpensive flat barrier to separate the atmospheres or fluids surrounding the two discs. This is our simplest and most versatile coupling.

 
Advantages of Disc Type Couplings
No Wearing Parts
Synchronous Design,
No Slip at Any Speed
No Physical Contact Between
Driving and Driven Parts
Simplifies Containment Barrier
Custom Designs Available
Note:
Disc Type Couplings are sold as hub halves;
weight per hub includes magnets.
