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.

Torque Couplings
Coaxial – these types of magnetic couplings are configured so that one member of the coupling is fully nested within the ID of the second member.  The two components share a common axis about which both rotate.
Axial misalignment – Very tolerant.
 In fact, it can easily be designed to accommodate very large axial misalignment if required.
Radial misalignment – Tolerant.
The amount of tolerance is based on the spacing between the driver and follower.  The larger the spacing, the greater the tolerance to radial misalignment.  Large radial offsets in closely spaced coupling may lead to excessive radial loads on bearings.
Angular misalignment – Tolerant
The amount of tolerance is based on the spacing between the driver and follower.  The larger the spacing, the greater the tolerance to angular misalignment.
Face to Face – these types of magnetic couplings are configured so that the magnetic flux is transferred about the flat end faces of  the cylindrical assemblies.  The two components are attracted to one and other axially, and typically require additional thrust bearing support for proper integration.
Axial misalignment – Mildly Tolerant.
The amount of torque transmission is directly proportional to the axial spacing and number of magnets utilized in the design.  Small variations in air gap may lead to large changes in torque
Radial misalignment – Highly Tolerant.
Angular misalignment – Tolerant
Due to the relationship between torque output and axial spacing, high angular misalignments may lead to unexpected reductions in torque
