Type MXC, Magnetic Couplings
While magnetic couplings do accommodate some radial, angular, and axial shaft misalignment, their primary purpose isn't this misalignment accommodation, but rather transmitting rotary motion across a barrier. A magnetic coupling consists of two banks of magnets with alternating polarity; the two banks engage each other magnetically and resist slipping, with a force inversely related to the gap between the banks.
By placing one bank on each side of a nonmagnetic, thin, flat sheet, it's possible to create a hermetically sealed rotary feed through. The coupling will also serve as a slip-clutch, as it slips to the next position 90 degrees out-of-phase under overload; and there is no contact, so there is no wear.
The type MXC is a very low-torque magnetic coupling, however, so applications are limited by the torque. And, although the OEP type MXC is less expensive than most magnetic couplings, it's more expensive than most of OEP Coupling's non-magnetic types.
The OEP type MXC actually includes 3 variations--MSC, MMC, and MLC, which vary from one another only in their hub diameter and in their ranges of bore diameter.
