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 ⁄” 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.
