Magnetic Couplings
WHY USE MAGNETIC DISC COUPLINGS?
Disc type magnetic 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.
Typical applications include magnetic mixers and magnetic drive pumps.
