Type of magnetic coupling
Type 1 -  Torque
Type 2 -  Linear
As their names imply, torque couplings (Type I) are used to transmit forces rotationally while linear couplings (Type II) are used to transmit forces linearly.  As one might expect, each coupling Type also has a variety of geometric topologies that can be utilized to meet the design intent.  The details of these configurations are found below.

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.
